Question

Which material will reach the highest temperature upon absorbing the same amount of heat? Assume the same mass and initial temperature for all materials. C_Au = 0.128 J/g degree C C_ethanol = 2.42 J.g degree C C_Fe = 0.449 J/g degree C CH_2 O = 4.18 J/g degree C Which of the following statements is correct? In an exothermic reaction, the surroundings will get colder. When heat is transferred from the surroundings to the system. In an endothermic reaction, heat is transferred from the system to the surroundings. All of the above statements are correct.

Explanation / Answer

The heat capacity of a defined system is the amount of heat needed to raise the system's temperature by one degree .
it means that on addition of same amount of heat the temp raise is maximum in the material with lowest heat capacity ie
a) Gold(Au)
