A gas-forming reaction produces 1.40 m of gas against a constant pressure of 172.0 kPa. Calculate the work done by the gas in joules. Number
2. If the volume of a gas increases by AV (liters) against a constant restraining pressure P (atm), the work transferred from the system (the gas) to its surroundings is PAV (liter atm) a. Work has units of energy but liter atm is not a convenient unit. Show how to convert 1.00 liter atm to joules (J). b. Suppose 201 cal are transferred to a gas in a balloon (as heat) and the gas expands What is the energy balance?...
Expand 1.00 mol of a monatomic gas, initially at 7.00 kPa and 737 K, from initial volume Vi = 0.875 m3 to final volume Vf = 2.90 m3. At any instant during the expansion, the pressure p and volume V of the gas are related by p = 7.00 exp[(Vi - V)/a], with p in kilopascals, Vi and V are in cubic meters, and a = 2.40 m3. What are the final (a) pressure and (b) temperature of the gas?...

A gas expands from 5.7 L to 8.1 L at constant temperature. Calculate the work done by the gas if it expands against a constant external pressure of 0.98 atm. Answer in units of joules.
A system of ideal gas has an initial pressure of 114 kPa and occupies a volume of 6.00 liters. Doubling the system’s absolute temperature by means of a constant-pressure process would require an amount of work W. Instead, you decide to double the absolute temperature by carrying out two processes in sequence, a constant-pressure process followed by a constant-volume process. In this case, the total work done in the two-process sequence is W/2. Calculate the final pressure of the system....
If 5.0 Liters of a gas is allowed to expand against a pressure of 1.10 atm to a 43.0 Liters and 2.5 KJ of heat is given off, calculate the work done and the internal energy change ∆E.
The volume of a gas decreases from 6 to 2 liters under a constant pressure of one atmosphere. Is the work done by the gas or on the gas? On the gas What work is done? Work Done = Number Joules If the internal energy inceases by 140, what was the net heat exchange? Heat Change = Number Joules
1. A gas is compressed slowly at a constant pressure of 150 kPa from an initial volume of 700 L to a final volume of 100 L. How much work is done by the gas in this process? Explanation: this constant pressure process is possible for a gas that is cooling off Hint: carefully consider the sign of your answer, the definition of work, and the force vectors Draw the picture to help understand it Answer: absolute value of the...
Compute the work done by a gas on the surrounds when it expands against a constant external pressure of 2.00 atm from 5.00 L to 10.00 L at 30C. If 2.00 atm is the gas pressure at 10.00 L, 30C, compute the number of mole of gas. Compute the work that must be done by the surrounds on the gas to return the gas to its initial state using one irreversible compression.
