The enthalpy and internal energy are the function of temperature for
The entropy of an isolated system can never
The standard enthalpy of formation of $C_2H_{4(g)}, CO_{2(g)}$ and $H_2O_{(l)}$ are $52, -394$ and $-286\, kJ\, mol^{-1}$ respectively. Then the amount of heat evolved by burning $7\, g$ of $C_2H_{4(g)}$ is
