A copper kettle weighs $1\mathrm{.}07kg.($The specific heat of copper is $0\mathrm{.}384\frac{J}{g}*C)$

$($a$)$ What is the heat capacity $($in $\frac{J}{}C)$ of the kettle?

$4\mathrm{.}0$

Check the number of significant figures. $\frac{J}{}C$

$($b$)$ How much heat $($in J$)$ is required to increase the temperature of this kettle from $21\mathrm{.}8C$ to $98\mathrm{.}9C?$

$4\mathrm{.}0.3$

$($c$)$ How much heat $($in J$)$ is required to heat this kettle from $21\mathrm{.}8C$ to $98\mathrm{.}9C$ if it contains $1\mathrm{.}32L$ of water $($density of $0\mathrm{.}997\frac{g}{m}L$ and a specific heat of $4\mathrm{.}184\mathrm{.}0]$
