An 8.00 X 102-g block of lead is heated in boiling water, 100.0°C, until the block's temperature is the
same as the water's. The lead is then removed from
the boiling water and dropped into 2.50 X 10² g of
cool water at 12.2°C. After a short time, the temper-
ature of both lead and water is 20.0°C.
a. How much heat is gained by the cool water?
b. On the basis of these measurements, what is the
specific heat of lead?

F500 j of energy were added to 1 kg of each of these samples, which would experience the least temperature increase?

Consider a one meter long horizontal pipe with a constant 100 cm^2 cross sectional area. water flows rightward into the pipe at x = 0 with flow velocity 02m/sec at every point within the pipe intake area. at x=1, the rightward flow rate is 0.192 m/sec. assume the water is a conserved quantity in the pipe, so there must be a leak (a sink) somewhere in the pipe. 1. compute net volumetric flow of the source if the system to be in equilibrium. 2. now assume the pipe in the problem has no leaks. compute the net volumetric rate of change for the system.
