A 12g sample of water increases in temperature from 283K to 305K, calculate the amount of energy added.
q=mCAT = (12)(4.18)(22) = 1103.52J
q=?
m=12g
C=4.18 J/g*K
Delta T= 305-283 = 22

Calculate the change in pressure of a 51mL sample gas currently at STP when the Temperature is increased to 341K and Volume has changed to 25mL
P1V1/T1 = P2V2/T2
P2 = (1atm)(51mL)(341K) / (273K)(25K)
P2 = 2.5atm
