Which of the following affects the vapor pressure of a liquid quizlet?

Vapor pressure describes the pressure of the vapor phase in equilibrium with the liquid phase of a substance. Intermolecular forces and temperature are the only factors that affect vapor pressure. For a given liquid, temperature is the only factor.

What happens to the volume when the pressure increases?

Boyle found that when the pressure of gas at a constant temperature is increased, the volume of the gas decreases. when the pressure of gas is decreased, the volume increases. this relationship between pressure and volume is called Boyle’s law. But you won’t get any change in volume.

Does area affect pressure?

You can see that for a given force, if the surface area is smaller, the pressure will be greater. If you use a larger area, you are spreading out the force, and the pressure (or force per unit area) becomes smaller.

What is pressure What does pressure depend on class 8?

Answer: Pressure is force unit per area. Pressure depends on two factors: The magnitude of force applied – the greater the force, the greater is its effect. The area over which the force is applied, i.e. the area of contact between the two objects.

What happen to pressure when area will decrease?

Since pressure is defined as Force/Area, a decrease in the area over which force is applied would result in an increase in pressure on this area. This is because moving your thumb over the opening reduces the area over which force is applied. As a result, pressure increases.

How does pressure change with temperature?

The pressure in PV=nRT is the force exerted by the gas on the walls of the container. As the temperature increases, the particles move faster, and therefore have greater speeds, so greater momentum and therefore greater force when they collide with the walls, so the pressure increases.

Does high pressure create heat?

Pressure by itself does not produce heat. An increase in pressure does produce heat. As you compress a quantity of gas, for instance, by pushing a piston into a cylinder, you cause every molecule that bounces into the piston wall to bounce back a little faster.

Does low pressure mean hot?

As water vapor condenses, it creates clouds, precipitation, and generally unsettled weather. Because air rises near areas of low pressure, this type of weather often occurs in lows. Locations to the south and east of a low center (a region known as the “warm sector”) will see warm, moist weather.
