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.
You need to look up the definition of equilibrium vapor pressure. The vapor pressure of water is determined only by its temperature.
To compare the vapor pressure of water in the two jars, you need to understand that vapor pressure is dependent on temperature, not on the amount of water. Thus, the vapor pressure in both jars will be the same if the temperature is equal. However, if the temperature varies, the vapor pressure will be higher in the jar with less water, as there is a higher concentration of water molecules available to vaporize.
