The temperature of a silver bar rises by 10.0°C when it absorbs 1.23 kJ of energy by heat. The mass of the bar is 525 g. Determine the specific heal of silver from these data.

To determine
Specific heat of silver.

Explanation

Given Info: Heat energy absorbed by silver bar is 1.23 kJ, the mass of the silver bar is 525 g, and temperature raises by 10.0°C .

Formula to calculate the specific heat of the silver bar is,

Q=mcΔT

• Q is heat energy absorbed by the silver bar,
• m is the mass of the silver bar,
• c is the specific heat of the silver,
• ΔT is the change in temperature.

Rearrange the above equation in terms of c .

c=QmcΔT

Substitute 1.23 kJ for Q, 525 g for m, and 10.0°C for ΔT to find c.

c=1
