Test: Vapor Pressure - Mechanical Engineering MCQ

Vapor pressure is closely related to molecular activity and temperature of the liquid

Vapor pressure is closely related to molecular activity but independent of the temperature of the liquid

Vapor pressure is not affected by molecular activity and temperature of the liquid

Vapor pressure is not affected by molecular activity and is independent of the temperature of the liquid

Vapor pressure increases linearly with the increase in temperature of the liquid

Vapor pressure increases slightly with the increase in temperature of the liquid at low temperatures and the rate of increase goes high at higher temperatures

Vapor pressure increases rapidly with the increase in temperature of the liquid at low temperatures and the rate of increase goes low at higher temperatures

Vapor pressure remains unchanged with the increase in temperature of the liquid

Absolute pressure of a liquid must be greater than or equal to it’s vapor pressure

Absolute pressure of a liquid must be less than or equal to it’s vapor pressure

Absolute pressure of a liquid must be equal to it’s vapor pressure

Absolute pressure of a liquid must be greater than it’s vapor pressure

Vapor bubbles are formed when the fluid pressure goes above the vapor pressure and collapses when the fluid pressure goes above the bubble pressure

Vapor bubbles are formed when the fluid pressure goes above the vapor pressure and collapses when the fluid pressure goes below the bubble pressure

Vapor bubbles are formed when the fluid pressure drops below the vapor pressure and collapses when the fluid pressure goes below the bubble pressure

Vapor bubbles are formed when the fluid pressure drops below the vapor pressure and collapses when the fluid pressure goes above the bubble pressure
