vec$(H)$ is the function of temperature. The vec$(H)$ of $"A"$ chemical changes linearly with increasing

temperature at $1$atm.

$($Q$1)$ Write the general equation for widehat$(H)$ as a function of temperature.

$($Q$2)$ What is the reference temperature $(T_{\text{r}\text{e}\text{f}})?$

$($Q$3)$ Write the equation for widehat$(U)(k\frac{J}{k}g)$ at $1$atm.

$($Q$4)$ The SBU CME students will cool $10kg$ of $"A"$ chemical from $60C$ to $10C$ in $10$min.

Calculate the heat transfer rate $(k\frac{J}{s}).$
