Molar heat capacity $(C_p)$ of water at constant pressure is $75 \ J \ K^{-1} \ mol^{-1}$. The increase in temperature (in $K$) of $100 \ g$ of water when $1 \ kJ$ of heat is supplied to it is

The $C_{p}$ of $H_{2}O_{(l)}$ is $75.3 \ J \ mol^{-1} \ K^{-1}$. What is the energy (in $J$) required to raise $180 \ g$ of liquid water from $10^{\circ}C$ to $15^{\circ}C$? $(H_{2}O = 18 \ u)$

Fill in the blanks:
$(i)$ The unit of heat capacity is ......... .
$(ii)$ Heat capacity is a ......... property of matter.
$(iii)$ The amount of heat required to raise the temperature of $1 \ mol$ of a substance by $1^{\circ} C$ is called ......... .

$20 \ cal$ of heat is required to increase the temperature of a $15 \ g$ piece of $Al$ metal from $25^{\circ}C$ to $30^{\circ}C$. Calculate the heat capacity,specific heat capacity,and molar heat capacity of the $Al$ piece. (Given: Atomic mass of $Al = 27 \ g \ mol^{-1}$)

For the reaction ${H_2}_{(g)} + \frac{1}{2}{O_2}_{(g)} \to {H_2}O(\ell)$,given $\Delta C_P = 7.63 \, cal/deg$ and $\Delta H_{25\,^{\circ}C} = 68.3 \, Kcal$,find the value of $\Delta H$ at $100\,^{\circ}C$ (in $Kcal$).

If $192 \ J$ of heat is required to increase the temperature of $45.0 \ g$ of silicon by $6 \ ^oC$,what is its specific heat capacity?
