Answer:
Q = 2790 J
Explanation:
Mass of silver bar is 250 g
It is heated from 22.0°C to 68.5°C
The specific heat of silver is 0.240 J/g°C
It is required to find the heat absorb by the silver bar. The heat absorbed by an object when heated from one temperature to another is given by :
[tex]Q=mc\Delta T\\\\Q=250\times 0.240\times (68.5-22)\\\\Q=2790\ J[/tex]
So, the heat absorbed by the silver bar is 2790 J.
