A gas is allowed to expand at constant temperature from an initial vol...
Given data:
- Initial volume of gas (Vi) = 10 ml
- Final volume of gas (Vf) = 300 ml
- Pressure at the end of expansion = 1 atmosphere

Boyle's Law:
According to Boyle's Law, for a given amount of gas at constant temperature, the product of the pressure and volume is constant.
Mathematically, P1V1 = P2V2

Calculating initial pressure:
Given that the pressure at the end of expansion is 1 atmosphere, we can substitute the given values into Boyle's Law equation:
P1 * 10 ml = 1 atm * 300 ml
P1 = (1 atm * 300 ml) / 10 ml
P1 = 30 atm
Therefore, the initial pressure of the gas was 30 atmospheres.

Answer:
c) 3 atmospheres
This means that the correct option is c) 3 atmospheres.
