TaAP - Thermodynamics

A system in which energy can cross the boundary but mass cannot is:

• a fixed system.

• an imaginary system.

• an open system.

• a closed system.

Properties whose values depend on the size/extent-of the system are:

• Intensive

• Extensive

An adiabatic process is one in which:

• there is no heat transfer.

• the process is reversible.

• the temperature remains constant.

• the entropy remains constant.

A thermodynamic cycle must:
