Question

Will a compound with lower specific heat decrease in temperature (get colder) more quickly than a compound with relatively higher specific heat when both are placed in a colder environment such that heat will flow away from the compounds.

Answer 1

Where Q is the heat added, C is the specific heat, m is the mass of the compound and dT is the change in temperature in K or degree celcius

So, specific heat depends on mass of the compound, heat added and temperature difference

But in a phase change, the heat added or removed does not change the temperature.

So, two cases arises; 1. if a compound with relatively high specific heat is placed in a colder environment, where phase change arises, there will not be any change in temperature

2. If a compound with relatively high specific heat is placed in a colder enviroment, where phase change does not arises, there will be decrease in temperature. In this case the compound with lower specific heat decreases its temperature more quickly than a compound with high specific heat.
