Solving for Water Temperature: 4000J Added to 400g at 20°C

[reallydumb]

4000J of heat energy are added to 400 grams of water at 20 degrees celsius. What is the resulting temperature of the water?

I know that I'm supposed to find Kelvin (K) but I'm not sure on which equation to use..

Hello,

Reading this page should help.

Look in your textbook and class notes, you should be able to find an equation that relates the quantities that are given / asked for (energy, mass, temperature).

Thats why I asked because I really can't find it in the book or notes

Please just tell me the equation xD

It's at the link Tsportmat gave. Have a look.

I started physics 2 months ago so I haven't a clue of most of the stuff in that link, we have'nt come across it yet

Anyway nevermind
