5.0 g of copper was heated from 20 degrees celsius to 80 degrees celsius. how much energy was used to heat cu( specific heat capacity of cu is 0.092 cal/g degrees celsius)

Explanation:

The energy used to heat a substance is related with its specific heat, the change in its temperature and its mass by the expression:

where Q is the heat needed, c is the specific heat, m is the mass and and are the final and initial temperatures respectively.

The problem gives you the information:

Replacing the values in the equation:

the answer is a and have a great day
