5. You have two sealed jars of water at the same temperature. In the first jar there is a large amount of water. In the second jar there is a small amount of water. Using 3 -4 sentences explain how the vapor pressure of water in the first jar compares with the vapor pressure of water in the second jar.

5.	You have two sealed jars of water at the same temperature.  In the first jar there is a large amount of water.  In the second jar there is a small amount of water.  Using 3 -4 sentences explain how the vapor pressure of water in the first jar compares with the vapor pressure of water in the second jar.

Well I'm guessing that since there is less space in the 1st jar compared to the 2nd for vapour, then there should be a greater vapour pressure in the 1st jar.

anonymous · Answer

Because it's the collisions between particles of a gas and the walls of the container that cause the pressure in a closed container. So even if there's the same amount of vapour in both jars with the 1st jar having less space for gas particles compared to the 2nd jar, there would be more collision between the gas particles and the walls of the 1st jar due to less space, and therefore greater pressure.

The presence or absence of any gasses that are not from the water in the makes a differences as well.
