Boyle's Law states that for a fixed mass of gas at constant temperature, the pressure of the gas is inversely proportional to its volume. Mathematically, this is expressed as P1 V1 = P2 V2.

Here is the solution for question 2(b), which applies Boyle's Law.

Boyle's Law states that for a fixed mass of gas at constant temperature, the pressure of the gas is inversely proportional to its volume. Mathematically, this is expressed as $P_1 V_1 = P_2 V_2$.

• Initial conditions:

  • Volume, $V_1 = 40 \text{ cm}^3$
  • Temperature, $T_1 = 0^\circ C$
  • Pressure, $P_1 = 680 \text{ mmHg}$

• Final conditions for part (b):

  • Temperature, $T_2 = 0^\circ C$ (constant)
  • Pressure, $P_2 = 380 \text{ mmHg}$
  • Volume, $V_2 = ?$
