b.

A volume of 0.0032 m30.0032\text{ m}^30.0032 m3 of glycerin is heated in a container for 8.0 min8.0\text{ min}8.0 min. The temperature of the glycerin increases from 18 ∘C18\ ^\circ\text{C}18 ∘C to 138 ∘C138\ ^\circ\text{C}138 ∘C.

The density of the glycerin is 1250 kg/m31250\text{ kg/m}^31250 kg/m3. The specific heat capacity of the glycerin is 2400 J/(kg ∘C)2400\text{ J/(kg }^\circ\text{C)}2400 J/(kg ∘C).

Calculate the mass of glycerin in the container.

[2]
c.

Calculate the thermal energy required to increase the temperature of the glycerin.

[3]
d.

Calculate the power required to supply the energy calculated in (b)(ii).
