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.
