Question 331

An electric heater is used to heat a metal block.

The temperature of the block rises from 15 ∘C15\ ^\circ\text{C}15 ∘C to 55 ∘C55\ ^\circ\text{C}55 ∘C.

The thermal energy supplied to the block is 36.0 kJ.

What is the thermal capacity of the metal block? (Ignore any heat loss to the surroundings.)
