1. in an isothermal process on a pv diagram, what remains constant throughout the process?

temperature
pressure
volume
internal energy

1. which type of thermodynamic process is represented by a vertical line on a pv diagram?

isobaric
isothermal
adiabatic
isochoric

1. during an adiabatic process, what is the heat transfer (q) equal to?

maximum possible value
equal to change in internal energy
equal to work done
zero

1. an isobaric process on a pv diagram appears as which type of line?

horizontal line
diagonal line
vertical line
curved line

1. the latent heat of vaporization is the energy required to

cool gas to condensation point
increase temperature of gas
heat liquid to boiling point
convert liquid to gas at constant temperature

Explanation:

1. In an isothermal process, temperature remains constant throughout.
2. A vertical line on a PV diagram represents an isochoric process (constant volume).
3. In an adiabatic process, heat transfer \(Q = 0\) (zero).
4. An isobaric process (constant pressure) on a PV diagram appears as a horizontal line.
5. The latent heat of vaporization is the energy required to convert liquid to gas at constant temperature.

Answer:

1. Temperature
2. Isochoric
3. Zero
4. Horizontal line
5. Convert liquid to gas at constant temperature
