What is the energy of a substance due to the movement of its molecules or atoms and energy is the sum of energy in motion and stored energy in objects?
In addition to the previous right answer, Prof. Rk Naresh , the energy of an object or system of objects is given by the internal energy U.
There are translational degrees of freedom for kinetic energy, but also those entities (molecules) have other types of degrees of freedom: vibrational, rotational, and electronic.
In a diatomic molecule as Carbon Monoxide (CO) all these degrees of freedom appear at different temperatures, as T increases. It can be seen in a plot of the specific heat as a function of temperature, and therefore the internal energy of the CO molecule contains all these degrees of freedom .
There is another simple example for an ideal gas that deviates from the Maxwell distribution for kinetic energy, and it is the distribution function of a system of particles in an external gravitational field.
Thermal energy, or heat, is the energy that comes from the movement of atoms and molecules in a substance. Heat increases when these particles move faster. Geothermal energy is the thermal energy in the earth. Motion energy is energy stored in moving objects. All molecules have energy and are in constant motion, they vibrate. This vibration is the energy of the matter and can be measured as temperature. Most matter expands when heated, and when cooled it contracts. The more energy something has, the higher its temperature and the more its molecules are vibrating. A common example of energy transfer that we see in everyday life is the transfer of kinetic energy—the energy associated with motion from one moving object to a stationary object via work. In physics, work is a measure of energy transfer and refers to the force applied by an object over a distance. The simplest mechanism by which molecules can cross the plasma membrane is passive diffusion. During passive diffusion, a molecule simply dissolves in the phospholipids bilayer, diffuses across it, and then dissolves in the aqueous solution at the other side of the membrane. Passive transport is a naturally occurring phenomenon and does not require the cell to expend energy to accomplish the movement. In passive transport, substances move from an area of higher concentration to an area of lower concentration in a process as diffusion. Active transport is the movement of molecules across a cell membrane from a region of their lower concentration to a region of their higher concentration. Motion energy also known as mechanical energy is the energy stored in moving objects. As the object moves faster, more energy is stored. Motion energy is the sum of potential and kinetic energy in an object that is used to do work. Potential energy, expressed in science as U , is energy that is stored within an object, not in motion but capable of becoming active. An object can store energy as the result of its position. For example, the heavy ball of a demolition machine is storing energy when it is held at an elevated position. This stored energy of position is referred to as potential energy. Similarly, a drawn bow is able to store energy as the result of its position. The mechanical energy of an object can be the result of its motion (i.e., kinetic energy) and/or the result of its stored energy of position (i.e., potential energy). The total amount of mechanical energy is merely the sum of the potential energy and the kinetic energy.
The energy of a substance due to the movement of its molecules or atoms is called thermal energy. Thermal energy is a type of kinetic energy, which is the energy of motion. The faster the molecules or atoms in a substance move, the more thermal energy it has.
The total energy of an object is the sum of its kinetic energy and potential energy. Potential energy is the energy stored in an object due to its position or configuration. For example, a ball held above the ground has potential energy because of its position relative to the ground.
Therefore, the statement that energy is the sum of energy in motion and stored energy in objects is correct. Thermal energy is a type of kinetic energy, which is energy in motion.
Here are some examples of thermal energy:
The energy of hot water
The energy of steam
The energy of a hot stove
The energy of a fire
The energy of the sun
Thermal energy can be transferred between objects in different ways, such as through conduction, convection, and radiation. Conduction is the transfer of thermal energy through direct contact between objects. Convection is the transfer of thermal energy through the movement of fluids. Radiation is the transfer of thermal energy through electromagnetic waves.
Thermal energy is important for many different processes, such as cooking, heating and cooling buildings, and generating electricity.
Thermal energy is the energy contained by atoms and molecules due to their motion and vibration. Thermal energy transfers through conduction, convection, and radiation. Conduction is the transference of thermal energy through collisions between neighboring atoms and molecules. Thermal energy is produced when a rise in temperature causes atoms and molecules to move faster and collide with each other. The energy which arises due to the motion of atoms or molecules in a body is known as thermal energy and it is a measure of average of kinetic energies of all the particles. Heat is the energy an object has because of the movement of its atoms and molecules which are continuously jiggling and moving around, hitting each other and other objects. All molecules have energy and are in constant motion, they vibrate. This vibration is the energy of the matter and can be measured as temperature. Most matter expands when heated, and when cooled it contracts. The more energy something has, the higher its temperature and the more its molecules are vibrating. Heat is the transfer of energy from a high-temperature body to a lower-temperature one. It is also described as energy in transit since it only occurs when there is a difference in temperature between two systems. Sound energy occurs when an object vibrates. Noise, whether within the human range of hearing or not, is sound energy. Sonar, ultrasonic (greater than 20 kilohertz) music, speech, and environmental noise are all forms of sound energy. Diffusion is defined as the net movement of molecules from an area of greater concentration to an area of lesser concentration. The molecules in a gas, a liquid or a solid are in constant motion due to their kinetic energy. Molecules are in constant movement and collide with each other.Motion energy also known as mechanical energy is the energy stored in moving objects. As the object moves faster, more energy is stored. Motion energy is the sum of potential and kinetic energy in an object that is used to do work. Mechanical energy, sum of the kinetic energy, or energy of motion, and the potential energy, or energy stored in a system by reason of the position of its parts. An object can store energy as the result of its position. For example, the heavy ball of a demolition machine is storing energy when it is held at an elevated position. This stored energy of position is referred to as potential energy. Similarly, a drawn bow is able to store energy as the result of its position. Kinetic energy is the energy of motion. Potential energy is the stored energy that can be used for motion. The total energy is the combined energy that stays constant when an object is moving and at rest or when spring is in equilibrium. Thermal energy, or heat, is the energy that comes from the movement of atoms and molecules in a substance. Heat increases when these particles move faster. Geothermal energy is the thermal energy in the earth. Motion energy is energy stored in moving objects.
