When air is pumped into a cycle tyre the volume and pressure of the air in the tyre both are increased. What about Boyle’s law in this case?

Answer:

We have,

PV = P(m/ρ) = constant

P/ ρ = constant

Volume = m/ ρ

where m is constant

When air is pushed into the cycle’s tyre, the mass of the air increases as the number of molecules increases. As a result, Boyle’s law is only valid when the gas’s mass remains constant.
