1. The increase and decrease of cp with increasing temperature is due to the change in the heat capacity of the sample. As the temperature increases, the heat capacity of the sample increases until it reaches a maximum value, then decreases as the temperature continues to increase. This is due to the fact that the molecules in the sample are vibrating more and more as the temperature increases, and the heat capacity of the sample is a measure of the amount of energy required to increase the temperature of the sample. 2. To determine if the domains of a protein interact with each other, we can look at the thermogram of the protein. If the thermogram shows a single peak, then the domains are likely not interacting with each other. However, if the thermogram shows multiple peaks, then this indicates that the domains are interacting with each other. This is because the multiple peaks indicate that the domains are undergoing different transitions at different temperatures, which suggests that they are interacting with each other.

Hai sir For the first question, increasing temperature causes an increase in collisions between particles, leading to an increase in the rate of chemical reactions. As the temperature increases further, these reactions become less efficient, causing the rate at which heat is generated to decrease, and hence the cp also decreases. For the second question, a Delta H/T graph can tell you if two domains interact with each other or not. Generally, when two domains interact, you will see an elevated enthalpy curve on the graph, whereas when two domains do not interact, the enthalpy remains steady.
