Question
The curve is drawn at constant temperature under pressure-volume relationship:
- Isobar
- Isotherms
- Isotones
- Isomers
Hint:
When the pressure is constant it is called isobar.
The correct answer is: Isotherms
The correct option is b)Isotherms
Curves drawn at constant temperature are called isotherms. This shows the relationship between pressure (P) and volume (V).
At constant temperature, the product of pressure and volume for a constant amount of gas is constant. This is known as Boyle's law.
The pressure (P) of a given gas mass varies inversely with its volume (V) at constant temperature.
P∝ 
PV= constant.
