Question

Which of the following statements is true?

When a liquid is sealed in a container at constant temperature, the vapor pressure

increases at first, then remains constant.

When a liquid is sealed in a container at constant temperature, the vapor pressure

continues to steadily decrease.

When a liquid is sealed in a container at constant temperature, the vapor pressure

increases at first, then decreases.

When a liquid is sealed in a container at constant temperature, the vapor pressure

continues to steadily increase.

Answer 1

Answer 2

Vapor pressure and temperature are proportional to one another, when you raise the temperature you raise the vapor pressure too. The external pressure stays the same, BUT if the temperature is constant so is the vapor pressure.

Answer 3

I think the vapor pressure may increase first but remain constant since the temperature is constant.

Answer 4

so what would the answer be @greatlife44

Answer 5

well, before i get into that do you understand what vapor pressure is?

Answer 6

The first one would be the answer A.

Answer 7

so the answer is When a liquid is sealed in a container at constant temperature, the vapor pressure

increases at first, then remains constant.

Answer 8

yes, but do you understand what vapor pressure is and why this might be the case?

Answer 9

not really

Answer 10

Every liquid has what we call a vapor pressure

Answer 11

molecules escape the liquid phase and go into the gaseous phase and exert a pressure.

Answer 12

the more these molecules that escape into the gaseous phase , the higher the vapor pressure will be.

Answer 13

some molecules are volatile meaning they don't really like staying in the liquid phase and will escape into the gaseous phase more readily.
