can someone give me a hand on this one?(adsbygoogle = window.adsbygoogle || []).push({});

How many grams of water at 20 degrees Celsius can be converted into steam at 500 degrees Celsius with 10 kJ of energy?

wat i know is that this question is 2 parts: Water being heated to 100 C (80 C change)using the specific heat of water n then having a temperature change of 400 C using the specific heat of steam.

wat i dont understand is how i am supposed to split up the 10 kJ? do i have to have only 1 equation?

thanks in advance
