Question

An iron ball and an aluminum ball of mass 100 g each are heated to the same temperature and then cooled to a temperature of 20°

Answer 1

Answer:

The specific heat of aluminum is greater.

Explanation:

It lost the most heat.

Answer 2

Answer:

specific heat of aluminium is more than the specific heat of iron

Explanation:

mass of both the balls, m = 100 g

heat lost by iron is 3.6 kJ and the heat lost by aluminium is 7.2 kJ.

The amount of heat required to raise the temperature of substance by 1°C of mass 1 kg is defined as the specific heat of the substance.

Here, the amount of heat required to raise the temperature of aluminium by teh same amount as that of iron and mass remains same, so it means the opecific heat of aluminium is more than the specific heat of iron.
