Question

During the increase of the gas temperature 2.5 times, the boiling point increased by 40%. How many times did the gas pressure change?​

Answer 1

I will help you

Let's say we change the volume of a gas under isothermal conditions, and we want to find the resulting pressure. Then, the equation of Boyle's law states that: p₂ = p₁ × V₁ / V₂ or p₂ / p₁ = V₁ / V₂. As we can see, the ratio of the final and initial pressure is the inverse of the ratio for volumes.
