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?

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

$A_{(g)} \to 2B_{(g)}$; $\Delta_rH = 20 \ kJ/mol$ at $300 \ K$. If $C_{p,m}(A) = 20 \ J \ K^{-1} \ mol^{-1}$ and $C_{p,m}(B) = 5 \ J \ K^{-1} \ mol^{-1}$,which of the following statements is correct?

$C_P$ is always greater than $C_V$ for an ideal gas. Choose the correct option.

The correct order of molar heat capacities measured at $298 \ K$ and $1 \ bar$ is:

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 $Kcal$).
