Two objects, $A\,$ and $B$ , are initially at room temperature. Each object is heated so that its temperature rises by $∘C15\,^\circ\text{C}$ .

The objects are then allowed to cool back to room temperature.

Object $A\,$ has a smaller thermal capacity than object $B$ .

Which row in the table shows the object that requires less thermal energy to heat up by $∘C15\,^\circ\text{C}$ and the object that loses less thermal energy as it cools back to room temperature?

	Less energy for heating	Less energy for cooling
A	$A$	$A$
B	$A$	$B$
C	$B$	$A$
D	$B$	$B$

Less energy for heating: $A$ ; Less energy for cooling: $A$

Less energy for heating: $A$ ; Less energy for cooling: $B$

Less energy for heating: $B$ ; Less energy for cooling: $A$

Less energy for heating: $B$ ; Less energy for cooling: $B$
