Question

A metallic barrel has a capacity of 220.0 l at a temperature of 18°C. The barrel is filled with an oil mixture up to the 200 l mark and sealed. What is the pressure inside the container if the temperature is increased to 42°C? Consider that atmospheric pressure is 1.01 × 10⁵ Pa and the coefficients of volume thermal expansion are β_oil = 340 × 10^-6 K^-1 and β_barrel = 64 × 10^-7 K^-1.

Select one:

a. 1.19 × 10⁵ Pa

b. 1.24 × 10⁵ Pa

c. 1.29 × 10⁵ Pa

d. 1.62 × 10⁵ Pa
