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.

Question

Can anyone help me with this question? Thank you!

Answer 1

To compare the vapor pressure of water in the first and second jars, we need to consider the amount of water in each jar. The vapor pressure of a liquid increases with temperature and the number of molecules at the liquid surface. Since the first jar has a larger volume of water, it has more water molecules at the surface, hence it will have a higher vapor pressure compared to the second jar with a smaller volume of water.
