Name the thermodynamic process

What is the name for this thermal process?

• isobaric

• isothermal

• isochoric / isovolumetric

• adiabatic

Answer explanation

The pressure remains constant.

What is the name for this thermal process?

• isobaric

• isothermal

• isochoric / isovolumetric

• adiabatic

Answer explanation

It is curved so it could be isothermal. Look at the ends. Because PV=nRT, Pv~T. This means that is the product of PV is equal at both ends then they are at the same temperature. That is not true here, so the curve must be adiabatic.

Answer explanation

It is curved so it could be isothermal. Look at the ends. Because PV=nRT, Pv~T. This means that is the product of PV is equal at both ends then they are at the same temperature. That is true here, this curve is isothermal.

Just to clarify, an isothermal curve is the same temperature everywhere along the curve.
