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

Explanation

To solve the question regarding Boyle's law in the context of pumping air into a cycle tyre, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Boyle's Law**: Boyle's law states that for a given mass of gas at constant temperature, the pressure of the gas is inversely proportional to its volume. Mathematically, it can be expressed as:
\[ P \propto \frac{1}{V} \quad \text{or} \quad PV = k \]
