Question

A 12 gram piece of metal is heated to 300 °C from 100 °C with 1120 Joules of energy. What is the specific heat of the metal?

Answer 1

The specific heat of the metal is 466.66 J/Kg°C.

Step-by-step explanation:

Given,

mass = 12 gram = 0.012 Kg

T₁ = 300°C

T₂ = 100°C

ΔT = 200°C

Q = 1120 Joules.

The Specific heat of the substance can be calculated from the formula,

Q = (mass) (ΔT) (Cp)

Substituting the values,

1120 = (0.012)(200)(Cp)

Cp = 466.66 J/Kg°C.

Therefore, the specific heat of the metal is 466.66 J/Kg°C.
