A certain amount of heat

Q

will warm

1\,\mathrm{g}

of material

X

3^{\circ}\,\mathrm{C}

and

1\,\mathrm{g}

of material

Y

4^{\circ}\,\mathrm{C}

. Which material has a higher specific heat capacity?

Solution:

\text{ Specific heat capacity } = \frac{Q}{m \cdot \Delta T}

\because

Specific heat capacity

\propto \frac{1}{\Delta T}

So material

X

has a higher specific heat capacity.
