Pressure inside a sealed container

In summary, the conversation discusses the calculation of pressure in a vessel containing 1ml of water and the rest being air at different temperatures. The individual is trying to determine the pressure using the ideal gas law and vapour pressure, but is struggling to find the solution. They are asking for guidance and suggestions on how to approach and solve similar problems.

Hi

I am trying to calculate the pressure in a vessel of 5ml that contains 1ml water while the rest can be considered as air. I would like to know the pressure at temperatures of 20C, 80C and 120C


I have a feeling its something to do with vapour pressure, and the ideal gas law but can't seem to work it out

Thanks in advance

You should show a little more of the work you already have done. Please follow the template.

PF isn't a Q&A website, we should not answer any question without knowing the work you've done or at least your approach into solving the problem ., What do you think the answer is, How can similar problems can be solved ?
 

1. What causes pressure to build up inside a sealed container?

The pressure inside a sealed container is caused by the collisions of gas molecules with the walls of the container. As the number of collisions increases, so does the pressure.

2. How does the temperature affect the pressure inside a sealed container?

According to the ideal gas law, as the temperature of a gas increases, the pressure also increases. This is because the gas molecules have more energy and therefore, collide with the container walls with more force.

3. Can the pressure inside a sealed container be changed?

Yes, the pressure inside a sealed container can be changed by altering the volume or temperature of the gas inside. For example, if the volume of the container is increased, the pressure will decrease, and vice versa.

4. What is the relationship between the amount of gas inside a sealed container and the pressure?

According to Boyle's law, the pressure and volume of a gas are inversely proportional. This means that as the amount of gas inside a sealed container increases, the pressure also increases.

5. Can pressure inside a sealed container be measured?

Yes, pressure inside a sealed container can be measured using a pressure gauge or sensor. This device measures the force exerted by the gas molecules on the walls of the container and gives a numerical value for the pressure.
