Question

Study the following graph can mark the incorrect statement following it.

• A. At zero volume all lines meet at $- 273.15^{0}C$. This temperature is known as absolute zero.
• B. Each line of the volume vs temperature at constant pressure of graph is called isotherm.
• C. All gases obey charles law at very low pressure and high temperature.
• D. Pressure remaining constant, volume of a gas is directly proportional to its absolute temperature.

Answer 1

Answer: (B)

Each line of the volume vs temperature at constant pressure of graph is called isotherm.

Answer 2

: Graphs of volume vs temperature at constant pressure are called isobars.
