Question

A family going fishing puts 1.2 kg of ice in a cooler. The initial temperature of the ice is -4.0 ∘C.

Part A When 2.1×105 J of heat has leaked into the cooler, what is the temperature now?

Answer 1

If heay has been given to the ice then the first process that will occur is that the ice will go from -4°C to zero degree Celsius. Then it will Melt at zero degree Celsius which we called latent heat .

So here only 210 KJ of energy is given to ice in which 10 KJ of enrgy will be used by ice to go from -4°C to zero degree Celsius and 410 KJ of energy to melt at zero degree Celsius so there is not enough energy of latent heat.

So the final temperature will be zero degree Celsius.

And here is the solution
