Question

The graph for Boyle's law is called

• A. Isotherm
• B. Hypertherm
• C. Hypotherm
• D. None of these

Answer 1

The correct option is A

Isotherm

The explanation for the correct option

(A) Isotherm

Boyles law

• At constant temperature, the pressure of a fixed amount (i.e., number of moles n) of gas varies inversely with its volume. This is known as Boyle’s law.
• Mathematically, the equation can be written as follows:-
• $PV=k$
• The value of constant $k$ depends upon the temperature of the gas, the amount of the gas, and the units in which p and V are expressed.

Graph for Boyles law

• Each curve corresponds to a different constant temperature and is known as an isotherm (constant temperature plot).
• Higher curves correspond to a higher temperature.

Hence, the graph for Boyle's law is called isotherm.

Thus, option (A) is the correct answer.
