What phase change is observed in the formation of clouds in the atmosphere and process called when a solid is heated and it directly changes into a gas?
The water in liquid or solid state, when receive the solar radiation, is heated and because of that, beguin a natural change of phase to gaseoseus state (water vapor), increasing the atmospere humidity. The Sun heat the surface of the Earth provoquing that the air be less heavy and begeans to move upward. When it moves upward, find less presure, beguins to expand and because of that, the temperature decrease and beguin again to form wather drops. If the process continues, the water drops increase into the atmospere and beguin to apear the clouds, that will continuing growing if the atmosphere be also heated.
Cloud formation is a physical change that occurs when water evaporates in the process of evaporation and then condenses in the air to create clouds. Precipitation returns this water to the ground. This procedure is performed over and over. As a result, cloud formation is a physical change. The air is no longer able to hold all that water vapor. The excess amount changes from a gas into a liquid or solid (ice). The process of water changing from a gas to a liquid is called "condensation," and when gas changes directly into a solid, it is called "deposition." These two processes are how clouds form. What phase change is observed in the formation of clouds in the atmosphere a condensation b deposition c evaporation d sublimation. The water vapour that accumulated in the atmosphere eventually cools down due to the low temperatures found at high altitudes. These vapours become tiny droplets of water and ice, eventually coming together to form clouds. When the water vapor in clouds cools, it can condense into a liquid and fall as rain or freeze into a solid and fall as snow or ice crystals. Earth is unique in that all three states of water exist on our planet's surface. If the temperature is cold enough, water vapor goes directly to ice crystals. This phase change is called deposition. High clouds known as cirrus clouds are formed by this process. Snow is also formed by this process, which is called the Bergeron Process. Condensation occurs when a gas/vapor loses energy or gains pressure to move to a liquid state. Sublimation happens when a gas is formed from a solid, skipping the liquid state. Deposition is the opposite process of sublimation and is when gas goes to a solid, skipping the liquid phase. Clouds form when air rises and becomes saturated in response to adiabatic cooling. Migrate, warmer air is pushed aloft. This results in adiabatic cooling and cloud formation. Cold fronts occur when warm air is displaced by cooler air. As a region of surface air is warmed, the molecules move faster and the air expands and becomes less dense. Less dense air rises through the cooler and denser air above it in the process of convection. These parcels of rising warm air, called thermals, can lead to the formation of cumulus clouds. The process in which a solid directly changes into a gaseous state is known as sublimation and the amount of heat energy required to convert a mole of solid directly into the gaseous state at constant pressure is known as the molar enthalpy of sublimation. Sublimation can be defined as the transition of a substance from the solid phase to the gaseous phase without changing into the liquid phase. This process is called evaporation. It occurs when particles at the exposed surface of a liquid absorb just enough energy to pull away from the liquid and escape into the air.
