Question 28
a.

A student is supplied with a small block of aluminium, a thermometer, and an electrical heater of power PPP.

There are two holes drilled in the aluminium block. The heater fits tightly into one hole and the student places the thermometer into the other hole.

The student uses this equipment when determining the specific heat capacity of aluminium.

State:

  • the other equipment the student will need
  • the measurements the student needs to take
  • the equation used when calculating the value of the specific heat capacity of aluminium.

b.

In a commercial kitchen, there is a large aluminium cooking pot. The mass of the cooking pot is 16 kg16\text{ kg}16 kg.

State what is meant by the thermal capacity of an object.

c.

The specific heat capacity of aluminium is 900 J/(kg∘C)900\text{ J}/(\text{kg}^{\circ}\text{C})900 J/(kg∘C). Calculate the thermal capacity of the aluminium cooking pot.
