A sample of hydrogen gas will behave most like an ideal gas under the conditions of (1) low pressure and low temperature (2) low pressure and high temperature (3) high pressure and low temperature (4) high pressure and high temperature

Ideal gas has several important properties that must be followed by real gases to behave like an ideal gas

so here we can say

1. all gas molecules moves at very fast speed in random direction

2. there should not be any interaction force between molecules of gas

3. all gas molecules must have to follow Newton's II law

4. There is no effect of gravity on the molecules of gas

so here if all above conditions are followed by gas then

the condition must be followed only at low pressure and high temperature

so correct answer is

(2) low pressure and high temperature
