Two Chemistry questions that I need help on if interested please!?

Posted on 2015-09-26 08:57:00 in Chemistry by

1.) A test tube containing 6.0 grams of water is raised from 10 degrees Celsius to 25 degrees Celsius. How much heat (in calories) has the water gained?

2.) A supply of water at 22 degrees Celsius is heated with a source that transfers energy to the water at a rate of 42 calories per minute. After 12 minutes, the temperature of the water is 40 degrees Celsius. Assuming that no energy was lost to the surroundings, what is the mass of the water?

I really just want help on starting and how to do the questions! Thank you! :)
