A lead pipe that weighs 14.0 lbs sits out in the sun. So is a bucket of water.
a) What is the pipe's weight in grams?
b) If the pipe temperature rises from 5.7°C to 62.8°C while
sitting
pipe?
c) If the water absorbs 272 kJ of heat from the sun and its
in the sun, how much heat (in J) is absorbed by the
temperature rises from 9.2 °C to 10.7°C, what is the mass
(in g) of water in the bucket?
d) If the hot pipe (at 62.8°C) is put into the bucket of water
(that is at 10.7 C), and they reach thermal equilibrium,
what will the final temperature of each be?
