Homework Statement
I have a certain amount of water, which is heated by a 12V battery, which has an electric current of 13A. I need to work out the time taken to reach boiling temp, where the specific heat of water is given as 4200 J kg -1 C -1? Also need to know how to calculate the time taken to vaporize all the water using the standard latent heat of vaporization?
Homework Equations
I = Q/T for the first part in working out the time taken to boil the water, but not sure?
The second part working out vaporization and the time to vaporize water, really no idea? Please help or offer some guidance.
