Why does liquid exert equal pressure at the same depth?
Liquid exerts equal pressure at the same depth due to the principle of hydrostatic equilibrium. This means that the weight of the liquid above a certain depth creates a pressure that is transmitted evenly in all directions. As a result, the pressure at a particular depth in a liquid is the same regardless of the shape or volume of the container holding the liquid.
A decrease in vapor pressure will cause?
A decrease in vapor pressure will cause the liquid to evaporate more slowly, as there will be fewer molecules escaping from the surface into the gas phase. This can result in a slower rate of evaporation and a decrease in the amount of gas molecules above the liquid.
What is mean by saturated liquid and vapor?
Any addition of thermal energy to a saturated liquid will cause it to vaporize. Any subtraction of thermal energy from a saturated vapor will cause it to condense.
What is the measure of the force exerted by a gas above a liquid?
The force exerted by a gas above a liquid is measured as pressure, typically in units such as atmospheres (atm) or pascals (Pa). This pressure is a result of the gas molecules colliding with the liquid surface and is influenced by factors such as temperature and the amount of gas present.
How is a person able to drink using a straw?
Because he creates lower air pressure in his mouth compared to the atmospheric pressure - thus the liquid is pushed through the straw as a result of pressure difference.
What happens to a liquid when you compress it?
When a liquid is compressed, its molecules are forced closer together, which increases the pressure and, in some cases, can cause the liquid to change phase and become a solid. The volume of the liquid decreases as a result of compression.
Can liquid nitrogen evaporate from a sealed container?
Yes, liquid nitrogen can evaporate from a sealed container due to its low boiling point of -196°C. The pressure will increase in the container as the liquid nitrogen evaporates, eventually leading to a rupture or explosion if the container is not designed to handle the buildup of pressure.
What happens to the system in which the contained liquid evaporates at room temperature?
As the liquid evaporates at room temperature, the system will experience a decrease in the amount of liquid present and an increase in the amount of vapor in the container. This will result in a change in the pressure and temperature within the system as the liquid continues to evaporate.
Why does the height of the liquid column in a barometer changes as atmospheric pressure changes?
Pressure tendancies measure short term weather. The mercury in a barometer will rise with atmospheric pressure denoting fairer weather and a fall in barometric pressure warns of inclement weather.
The tendency of the molecules of a liquid at a given tepmpature to evaporate as a result of radom molecular motion?
This is known as vapor pressure. It is influenced by factors like temperature, intermolecular forces, and surface area. Higher temperature and weaker intermolecular forces increase the vapor pressure of a liquid.
What may result if a pressure regulator is not used on the type of gas or pressure range which it was designed?
A pressure regulator is a valve that automatically cuts off the flow of a liquid solid or gas at a certain pressure. So if it's not used on the item for which it was designed there could be an explosion or fire!
What would result in being able to dissolve a greater amount of gas in a solution?
"INCREASING THE PRESSURE" this is the answer key in my test.
