What is used to measure heat?

A. Change in temperature
B. Constant temperature
C. Constant specific heat
D. Change in specific heat



Answer :

Final answer:

Specific heat and heat capacity measure the energy needed to change substance temperature in calorimetry.


Explanation:

Specific heat and heat capacity are measures of the energy needed to change the temperature of a substance. The relationship between heat, mass, specific heat, and temperature change is given by the equation Q = mcΔT.

In calorimetry, heat transferred in a process is measured by carefully monitoring temperature changes. Specific heat values are crucial for these calculations and are used in a calorimeter to determine the heat exchanged during physical or chemical changes.

The specific heat is defined as the amount of heat required to change the temperature of a mass unit by one degree Celsius. It is an essential property used to calculate temperature changes in materials.
