Question

describe as fully as you can how the vapour pressure of propane changes with temperature

Answer 1

Answer:

Propane has a boiling point of -42°C. This means it is normally a gas. ... Similarly, butane has a boiling point of -0.5°C which can be raised to 38°C by increasing its pressure to 2.6 atmospheres. So, by compressing the gases, we get them to turn from a gas to a liquid at room temperature.

Answer 2

Vapour pressure of propane changes with temperature and at greater than atmospheric pressure it acts like a liquid.

Explanation:

• Propane is a member of the alkane family.
• It has a boiling point of $-42^{o}C$.
• It is normally a gas.
• Butane has a boiling point of $-0.5^{o}C$
• At any temperature, propane will remain in liquid form because its vapor pressure is less than the atmospheric temperature.
• The vapor pressure of propane is greater than the atmospheric pressure, therefore the liquid will vaporize.

Answer 3

Vapour pressure of propane changes with temperature and at greater than atmospheric pressure it acts like a liquid.
