Determine the mass of a sample of silver if 705 J of heat are required to raise its temperature from 25 C to 35 C . The specific heat of silver is 0.235 J/g C .

[dr b]

(heat required) = (mass)(specific heat)(change in temperature); solve for mass.

The amount of heat needed to heat a subject from one temperature level to an other can be expressed as:

Q = cp m dT (2)

where

Q = amount of heat (kJ)

cp = specific heat (kJ/kg.K)

m = mass (kg)

dT = temperature difference between hot and cold side (K)
