How many joules of heat are necessary to raise the temperature of 350ml of water from 1.00 °C to 5.00 °C?

Question

I don't understand how to solve this problem. My teacher did not explain it very well to me and I have problems figuring out how to put it into the equation, I know how to do the calculations, but how do you put it into the equation.

Answer 1

The equation you want is q = mCdeltaT

q = heat

m = mass = 350 g assuming 1 ml water = 1 g

C = specific heat of water = 4.184 J/g/degree

delta T = change in temperature = 5 - 1 = 4 degrees

Solving for q: q = (350g)(4.184 J/g/deg)(4 deg) = 5858 J
