Find the isothermal bulk modulus of an ideal gas at a pressure of 3 atm, in units of $1 0^{5}$ Pa (two decimals, 1 atm = $1.013 \times 1 0^{5}$ Pa).

Answer:

3.04

Solution:

For an isothermal change $P V = constant$ , so $B = - V \frac{d P}{d V} = P = 3 \times 1.013 \times 1 0^{5} = 3.04 \times 1 0^{5}$ Pa. The modulus rises with pressure.
