Quiz zum Vortrag
What is the formula for the amount of work done by the system at constant pressure?
- Amount of work done = pressure x change in volume
- Amount of work done = pressure x change in energy
- Amount of work done = pressure x change in temperature
- Amount of work done = pressure x change in the length of the system
- Amount of work done = change in internal energy
System A undergoes an adiabatic process from volume V₁ and pressure P to volume V₂ > V₁. System B undergoes an isothermal process from volume V₁ and pressure P to volume V₂ > V₁. Which system has done more work and why?
- System B has done more work because in the pressure-volume diagram the curve of system B remains above the curve of system A throughout the process.
- System B has done more work because in the pressure-volume diagram the curve of system B remains below the curve of system A throughout the process.
- System A has done more work because in the pressure-volume diagram the curve of system A remains above the curve of system B throughout the process.
- System A has done more work because in the pressure-volume diagram the curve of system A remains below the curve of system B throughout the process.
- Both have done the same amount of work since the area under their curves in the pressure-volume diagram is the same.
When is a system considered isochoric, isothermal, adiabatic or isobaric?
- Isochoric : volume held constant, isothermal: temperature held constant adiabatic: No heat transfer (Q = 0), isobaric: pressure held constant
- Isochoric : volume held constant, isothermal: No heat transfer (Q = 0) adiabatic: temperature held constant, isobaric: pressure held constant
- Isochoric : pressure held constant, isothermal: temperature held constant adiabatic: No heat transfer (Q = 0), isobaric: volume held constant
- Isochoric : volume held constant, isothermal: temperature held constant adiabatic: pressure held constant, isobaric: No heat transfer (Q = 0)
- Isochoric : volume held constant, isothermal: pressure held constant adiabatic: No heat transfer (Q = 0), isobaric: temperature held constant
The volume of a gas is doubled as its pressure is held constant at 1 atm. If the initial volume of the gas is 1 L, how much work is done by the gas? (1 atm = 100,000 Pa, 1 L = 0.001 m³)
