Answer:
Q = 146.25 J
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 :
[tex]Q=mc\Delta T\\\\Q=25\times 0.39\times (38-23)\\\\Q=146.25\ J[/tex]
So, 146.25 J of energy is absorbed by the pennies. Hence, this is the required solution.
