Part A:

How much work (in J) is required to expand the volume of a pump from 0.0 L to 2.8 L against an external pressure of 1.2 atm ?

Express your answer using two significant figures.

W =

Part B:

What is the mass of the silver block?

Express your answer to two significant figures and include the appropriate units.

A silver block, initially at 55.6 ∘C, is submerged into 100.0 g of water at 24.2 ∘C, in an insulated container. The final temperature of the mixture upon reaching thermal equilibrium is 26.9 ∘C.

1) A tank is full of water. Find the work W required to pump the water out of the spout. (Use 9.8 m/s2 for g. Use 1000 kg/m3 as the weight density of water. Assume that a = 4 m, b = 4 m, c = 12 m,and d = 1 m.) W = ___ J I got 5017600 then in scientific notation it would be 5.0176 X 10^6, then in Juls in would be 5.02? I got the answer...
