PH-2178

Specific heat capacity

Physics · Secondary 4 · Hard · Specific heat capacity

A heater supplies

9.0\times10^{5}\,\text{J}

of energy to

1.5\,\text{kg}

of water, raising its temperature from

20^{\circ}\text{C}

to

80^{\circ}\text{C}

. What is the specific heat capacity of the water?

$4.2\times10^{3}\,\text{J kg}^{-1}\,^{\circ}\text{C}^{-1}$
$6.0\times10^{3}\,\text{J kg}^{-1}\,^{\circ}\text{C}^{-1}$
$1.0\times10^{4}\,\text{J kg}^{-1}\,^{\circ}\text{C}^{-1}$
$1.5\times10^{4}\,\text{J kg}^{-1}\,^{\circ}\text{C}^{-1}$
