Question

A 2kg metal cylinder is supplied with 1600J of energy to heat it from 5*C to 13*C. What is the SHC of the metal?

Answer 1

100Jkg/°C

Step-by-step explanation:

Given parameters:

Mass of metal = 2kg

Amount of heat energy = 1600J

Initial temperature = 5°C

Final temperature = 13°C

Unknown:

Specific heat capacity of the metal = ?

Solution:

Specific heat capacity of a body is the amount of heat needed to raise the temperature of unit mass of a body by 1°C.

H = m x C x (T₂ - T₁ )

H is the amount of heat

m is the mass

C is the unknown specific heat capacity

T is the temperature

Insert the parameters and solve;

1600 = 2 x C x (13 - 5)

1600 = 16C

C = 100Jkg/°C
