A 12 m3 volume of ideal gas is expanded adiabatically. If the work done by the gas is 900 J what is the change in internal energy of the gas?
The answer is -900J but I don't know how to get this answer.. Show all work!
Thanks!
total heat given to the system(q) = change in internal energy(delta U) + work done by the gas(w)
now., for adiabatic processes,q = 0
thus, change in internal energy(delta U) = - work done by the gas(w) = -900 J

13. A diatomic ideal gas is at a pressure of 5 kPa and a volume of 4 m3. What is the change in internal energy of the gas when it doubles in volume adiabatically?
An ideal monatomic gas is contained in a vessel of constant volume 0.470 m3. The initial temperature and pressure of the gas are 300 K and 5.00 atm, respectively. The goal of this problem is to find the temperature and pressure of the gas after 30.0 kJ of thermal energy is supplied to the gas. (a) Use the ideal gas law and initial conditions to calculate the number of moles of gas in the vessel. mol (b) Find the specific...
A cylinder with a piston contains 0.140 mol of nitrogen at 1.88 105 Pa and 325 K. The nitrogen may be treated as an ideal gas. The gas is first compressed isobarically to half its original volume. It then expands adiabatically back to its original volume, and finally it is heated isochorically to its original pressure. PLEASE do B and C and don't don't forget to show all the steps specially for B becuase I don't know how to do...
A fixed quantity of an ideal monatomic gas of volume 0.074 m3, expands adiabatically. The initial and final temperatures are 24°C and -68°C. What is the final volume of the gas? _____m3
A sample of n moles of a monatomic ideal gas is expanded isothermally and reversibly at a constant temperature T from a volume V to 3V. Note that since the temperature of the gas is constant, the internal energy will remain constant. a) Write an expression for the change in entropy ΔS for the system. b) The sample has 7 moles of gas and is kept at a temperature of 305 K. The volume is changed from 0.065 m3 to...
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?
