Question : 42

Total: 50

in Boyle's law?

Solution:

Concept:

Boyle's law relates the pressure and volume of a fixed mass of gas at constant temperature.

Explanation:

According to Boyle's law, when temperature is kept constant, the pressure of a gas is inversely proportional to its volume.

This means that as volume increases, pressure decreases, and as volume decreases, pressure increases.

Mathematically,

P \propto \frac{1}{V}

PV = \text{constant}

Therefore, under constant temperature, volume varies inversely with pressure.

Answer:

D. T is constant, V varies inversely with P.
