Question

In order to calculate the amount of heat transferred you must know the __ and specific heat of the material, as well as the change in temperature. a. volume b. density c. mass d. enthalpy

Answer 1

Answer:

c. Mass  

Step-by-step explanation:

The formula for the heat transferred is

q = mCΔT

Thus, to calculate the amount of heat transferred you must know the mass and specific heat capacity of the material as well as the change in temperature.

Answer 2

Answer: The correct answer is Option c.

Explanation:

Specific heat of a substance is defined as the amount of heat required by 1 gram  of a substance to raise the temperature to 1 unit. It is represented by symbol by 'c'.

The chemical equation used to calculate the amount of heat transferred is given as:

$q=mc\Delta T$

where,

q = heat absorbed or released

m = mass of the substance

c = Specific heat of that substance

$\Delta T$ = change in temperature

We need mass of the substance with change in temperature as well as specific heat in order to calculate the amount of heat transferred.

Hence, the correct answer is Option c.
