How much heat is absorbed by 60 g of copper (c=385 J/kg K) when it is heated from 20°C to 80°C?

Q = 1386  J

Explanation:

Mass, m = 60 g = 0.06 kg

Specific heat of copper, c=385 J/kg K

It is heated from 20°C to 80°C.

We need to find the heat absorbed. It can be given by the formula as follows :

So, 1386  J of heat is absorbed.

continuous conducting path for current, power supply

option number c is the right answer.
