Question

A sample of an unknown metal has a mass of 0.5 kg. Adding 1985 J of heat to the metal raises its temperature by 10 K. What is the specific heat of the metal

Answer 1

Answer:

Cp = 397 [J/kg*K]

Explanation:

By means of the energy equation for heat transfer in substances and objects, we can calculate the specific heat. In this way, we have the following equation.

$Q=m*C_{p}*DT$

where:

Dt = temperature change = 10 [K]

m = mass = 0.5 [kg]

Q = heat = 1985 [J]

Cp = specific heat [J/kg*K]

Now replacing:

$1985=0.5*C_{p}*10\\C_{p}=\frac{1985}{0.5*10}\\C_{p}=397[\frac{J}{kg*K} ]$
