Answer 1

Q = 146.25 J

Step-by-step explanation:

Given that,

The mass of 10 copper pennis = 25 grams

It warm up from 23°C to 38°C.

The specific heat capacity of copper is 0.39 J/g°C

We need to find the energy absorbed by the pennies. The expression for the energy absorbed is given by :

`Q=mc\Delta T\\\\Q=25* 0.39* (38-23)\\\\Q=146.25\ J`

So, 146.25 J of energy is absorbed by the pennies. Hence, this is the required solution.
