Homework Statement



1.0 g of water at 28 degree celcius is placed into a 200g aluminium can at 300 degree celcius. What is the temperature of the aluminium can after all the water vapourises? Given the specific heat capacity of aluminium, 900 J/kg/degree celcius and water, 4200 and specific latent heat of water, 2.26 x 10^6 J/kg assuming no heat is loss to the surrounding.

Homework Equations





The Attempt at a Solution



I am not sure how to go about when it comes to combined specific heat capacity. Do we simply add them up?

Find the amount of heat needed to rise the temperature of 1 g of water from 28 degree celsius to 100 degree celsius.
Next find amount of heat needed to evaporate 1 g of water from 100 degree celsius to 1 g of steam at 100 degree celsius. Find the total amount of heat.
This much heat is lost by the aluminum can.
