Homework Answers
First statement is wrong statement.
Adding the same amount of heat to two different objects will produce the same increase in temperature.
Q=m c dT
where m mass of the substance and c specific heat capacity.
if we take the aluminium and iron they have the different specific heats hence the temperature increse may not be the same for both the substances.
Reamining all the statements are correct.

The amount of heat needed to raise the temperature of 1 mole of a substance by...
The amount of heat needed to raise the temperature of 1 mole of a substance by one Celsius degree (or, equivalently, one kelvin) is called the molar heat capacity of the system, denoted by the letter C. If a small amount of heat dQ is put into n moles of a substance, and the resulting change in temperature for the system is dT, then C=1ndQdT. This is the definition of molar heat capacity--the amount of heat Q added per infinitesimal...
