Week 6 - Types of Heat Engines Capabilities

The internal combustion engine in your car is a form of which engine type:

The maximum possible efficiency of a heat engine is determined by:

Which cycle is represented by the attached image?

This engine cycle is used in some submarines due to its low noise output and is also used in solar engines. It is also favored for uses in which a high energy fuel like petrol or diesel cannot safely be used. [blank_start]Stirling[blank_end]

What type of compression enables cold vapor from an evaporator in a refrigerator is [blank_start]adiabatic[blank_end] compression.

Which of the following heat engines are used to move energy from a cold region to exhaust it into a hot region. This can be done via phase changes.

If the volume on a gas is shrinking, how would you describe the work involved with the gas?

If the pressure on a gas is increasing, how could you describe the work involved?

If the pressure on a gas is decreasing, how could you describe the action of the heat in the system?

As a general rule, if your PV diagram is moving to the right, work is being done [blank_start]by[blank_end] the gas. If your PV diagram is moving to the left, work is being done [blank_start]on[blank_end] the gas. If there is no left or right motion of your PV diagram, [blank_start]no[blank_end] work is being done on or by the gas.
