Media Image

The work done by the system/gas in this PV-diagram is

negative

positive

zero

Answer explanation

"Zero," because the volume does not change. W=PΔVW=P\Delta V

Media Image

The work done by the system/gas in this PV-diagram is

negative

positive

zero

Answer explanation

Positive because the final PV is larger than the initial PV.

W=PΔVW=P\Delta V

Media Image

The work done by the system/gas in this PV-diagram is

negative

positive

zero

Answer explanation

The pressure stays the same and volume increases.

W=PΔVW=P\Delta V

MULTIPLE CHOICE QUESTION

20 sec • 1 pt

Media Image

The work done by the surroundings in this PV-diagram is

negative

positive

zero

Answer explanation

The pressure stays the same and volume increases. This means the work by the gas is positive. The work of the surroundings is the opposite sign of the work of the system/gas. So it would be negative.

 Wsystem=PΔVW_{system}=P\Delta V

MULTIPLE CHOICE QUESTION

20 sec • 1 pt

Media Image

The work done by the surroundings in this PV-diagram is

negative

positive

zero

Answer explanation

No change in volume means, no work ...at all.

Wsystem=PΔVW_{system}=P\Delta V

MULTIPLE CHOICE QUESTION

30 sec • 1 pt

Media Image

What equal zero for this PV-diagram

Change in Internal Energy

System's Thermal Energy

Work by the system/gas

Answer explanation

This diagram is an isothermal line. Which means the internal energy does not change.

ΔU=0\Delta U=0

MULTIPLE CHOICE QUESTION

30 sec • 1 pt

Media Image

What goes to zero on this PV-diagram

Change in internal energy

System's thermal energy

System's work

Answer explanation

The volume must change for work to occur.

Wsystem=PΔVW_{system}=P\Delta V


This graph does not have a change in volume so no work occurs.

Media Image

What goes to zero on this PV-diagram

Change in internal energy

System's thermal energy

system/gas's work

Answer explanation

This is an adiabatic process. Adiabatic means the no thermal energy crosses into the system. Q = 0
