Question

What is the specific heat of copper if a 75 g sample is heated from 20°C to 24°C by adding
117 j?

Answer 1

Answer:

Specific heat capacity of the copper is given as

$s = 0.39 J/g ^oC$

Explanation:

As we know that the heat required to raise the temperature of the given substance is given as

$Q = ms\Delta T$

here we know that

$Q = 117 J$

mass of the given part is

$m = 75 g$

change in temperature due to heat supply is

$\Delta T = 24 - 20 = 4^oC$

now we have

$117 = 75 (s)(4)$

$s = 0.39 J/g ^oC$
