4.5. The pressure p of a gas is given by the expression log p = 21.6–2420/T,where T is the temperature in kelvins. Using the exact value of p from this

expression, at T=400 K, and the Taylor-series expansion for p(T), compute the pressures at 410, 420, and 450 K. Compare these values with the exact ones obtained from the given expression. Refer to Example 4.1b.
