Question

Find the amount of heat needed to raise the temperature of a silver container of mass 100 g by 10°C. (c = 0.056 cal/gT)

Answer 1

Given:

Mass of the silver container (m) = 100 g

Change in temperature (ΔT) = 10°C

Specific heat of silver (c) = 0.056 cal/g°C

To find:

Heat energy (Q)

Formula:

Q = m · c · ΔT

Calculation:

Q = 100 × 0.056 × 10 Q

= 56 cal

The amount of heat needed to raise the temperature of the silver container is 56 cal.
