Suppose heat is transferred at a rate of 500 W into 1 L of water. The water starts at 20˚C.

a) How much heat is required to raise the water temperature to 100 ˚C? How long does this take?

b) How much heat is required to boil off half the water? How long does this take? Comment on the value compared to part a.

c) Plot temperature vs Q for this heating process. You should only need 3 points for the graph, connected by straight lines. You should have this information from the previous steps.

Solutions

Expert Solution

As any problem in physics, the solution begins by identifying known quantities and relating them to the symbols used in the relevant equation. In this problem, we know the following:

m = 1000 g
C = 4.18 J/g/°C
T_initial = 20°C
T_final = 100°C

X axis - Temperature in celcius

Y axis - Heat in Lakhs joule
