$1.$ How much energy is needed $($in kWh$)$ to

heat $10$ kg of water from $25$C to $85$C in a

sterilizer?

$2.$ If the electric stove operates at $80\%$

efficiency, how much electrical energy must

be supplied to the stove to meet the required

heat input for sterilization?

$3.$ Discuss how understanding the heat

balance can help design more energy$-$

efficient sterilization processes in medical

settings.
