Problem 1: Ideal Gas Law
Problem 1. The ideal gas law states PV nRT where P, V, and T are the pressure, volume and absolute temperature; n is the number of moles of gas; and R is the the ideal gas constant. Consider a 1-gallon canister of gas at a pressure of 1 atm. Answer the following questions: 1. How much energy would be needed to increase the pressure of the closed canister to 50 psi without changing its volume?...

An ideal gas expands from 26.0 L to 80.0 L at a constant pressure of 1.00 atm. Then, the gas is cooled at a constant volume of 80.0L back to its original temperature. It then contracts back to its original volume without changing temperature. Find the total heat flow, in joules, for the entire process. total heat flow:

During a constant pressure, nonflow (closed system) process, a gas loses 103 BTUs of heat to the surroundings while it's volume changes from 2.2 ft3 to 0.7 ft3. If the temperature of the gas decreases by 7 oF and the system contains 3.3 lbm of gas, find the absolute pressure of the system in lbf/in2. cV for this gas is 0.229 BTU/lbm-oF. (Hint: For this process, ∆U = mcV∆T even though the process is not carried out at constant volume). State...

In an engine, an almost ideal gas is compressed adiabatically (see Note below) to half its volume. In doing so, 2630 Joules of work is done on the gas. (a) How much heat flows into or out of the gas? (b) What is the change in internal energy of the gas? (c) Does its temperature rise or fall? Note: An adiabatic process is one that occurs without transfer of heat or matter between a thermodynamic system and its surroundings. In...
