A student claims that when two bodies not initially in thermal equilibrium are placed in contact, the rise in temperature of the cooler body must always be equal to the drop in temperature of the warmer body. Do you agree? Is there a principle of conservation of temperature or something like that?

Explanation:

No.

There is a difference between energy, called heat in this case, and temperature, which is a measure of the amount of heat contained in a material and is dependent on the material properties.

Temperature difference is what causes heat to move from one body to another.

Two objects at different temperatures placed in contact with one another will cause heat to move from the warmer body to the colder body until the temperature difference is eliminated.

The amount of heat leaving the warmer body will exactly equal the amount of heat absorbed by the cooler body. (assuming isolated system of two bodies) The temperature change within each of those bodies could be vastly different.

Example would be a 2 mm bead of molten lead dropped into a liter glass of tap water. The lead may cool several hundred °C as it solidifies while the water temperature would increase less than 1 °C

The rise in temperature of a colder body is not equal to the drop in the temperature of a hotter body ( i.e. student claim is false ).

When two bodies of different temperatures are placed in contact with one another, the hotter body will lose some of its energy ( heat energy ) to the colder body until the temperature difference between the bodies is eliminated ( i.e. until they attain an equilibrium temperature ) and this occurs at the same rate.    while

Temperature represents the amount of heat energy contained in a body. therefore The rate at which the bodies either lose or gain temperature when in contact  will differ due to the differences in their physical properties therefore the claim made by the student is scientifically wrong. .

Hence we can conclude that The rise in temperature of a colder body is not equal to the drop in the temperature of a hotter body ( i.e. student claim is false ).
