Question

3. How does the vapor pressure of water at 10°C compare with its vapor pressure at 50°C? The vapor pressure of water is lower at 50°C than it is at 10°C. The vapor pressure of water is the same at 50°C as it is at 10°C The vapor pressure of water is greater at 50°C than it is at 10°C.

Answer 1

Answer :The vapor pressure of water is greater at 50°C than it is at 10°C.

Explanation: Vapor pressure is the pressure exerted by the vapors over the surface of the liquid.

Vapor pressure is directly proportional to the temperature as more is the temperature, more liquid can be converted to vapors and more vapors will exert greater vapor pressure.

As 50 ° C > 10 ° C, at 50 ° C, vapor pressure will be more as compared to 10 ° C.

Answer 2

Answer:

The vapor pressure of water is greater at 50°C than it is at 10°C.
