**1. Homework Statement**

How much heat is required to raise the temperature of 0.250kg of water from 20.0oC to 30.0oC?

If this amount of heat is added to an equal mass of mercury that is initially at 20.0oC, what is its final temperature?

**2. Homework Equations**

Q=c*M*(t2-t1)

**3. The Attempt at a Solution**

for the first part i got

q=1*0.250*(30.0-20.0)

q=10.4725

this is wrong the correct answer was 1.05*10^4

how did they get that answer?

The second part i have so far

1.05*10^4=c*0.250*(t2-20)

it didnt say what the spefice heat of mercury was so i looked it up and it was 0.140

1.05*10^4=0.140*0.250*(t2-20)

1.05*10^4/(.035)+20

please help with this
