Question
I need help with just the setup on these questions, powerpoint shows the answer, however i would like to know how to calculate these questions TIA.. A sample of water at 10.0 ° C absorbs 4410 J of heat energy. The temperature of the sample increases to 72.0 °C. What is the mass of the water? The specific heat of liquid water is 4.184 J/g°C.
and,
A sample of liquid water at 100. °C absorbs 113 kJ of heat energy. How much of the water will be converted to steam? The heat of vaporization of water is 2259 J/g.
Explanation / Answer
Q = m*C*dT
m = Mass
C = specific heat of liquid water is 4.184 J/g°C.
dt = temperature difference
4410 = m x 4.184 x 72-10
m = 17
Mass of the water is 17 gm.
question 2
113 x 103 = m x 2259
m = 50.02 gm
50.02 gm of the water will be converted to steam
