A gas is compressed at a constant pressure of 0.800atm from 9.00 L to 2.00 L 400 J of energy leaves the gas by heat.

(a) What is the work done on the gas?

(b) What is the change in its internal energy?

 7,000 lb/hr of aniline is to be heated from 100 to 150 °F by
cooling 10,000 lb/hr of toluene with an initial temperature
of 185 °F in 2- by 1-in IPS double pipe hairpin exchangers

factor of 0.005 is required. (b) How many hairpin sections
are required? (c) How shall they be arranged? (c) What is the
final dirt factor?
