What is the approximate vapor pressure when the gas condenses at 80oC?
The vapor pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature. The vapor pressure depends on the temperature and the substance.
What happens to the pressure of a confined gas at a constant temperature when the volume is reduced by half?
When the volume of a confined gas is reduced by half at a constant temperature, the pressure of the gas will double according to Boyle's Law. This is because the product of pressure and volume is constant for a given amount of gas at constant temperature. When the volume decreases, the pressure increases to maintain this equilibrium.
What is the relationship that exists between mass and pressure?
The relationship that exists between mass and pressure is that the absolute pressure and volume of a given mass of confined gas are inversely proportional, while the temperature remains unchanged within a closed system.
What is the accurate definition of vapor pressure?
Vapor pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature in a closed system. Vapor pressure is also known as equilibrium vapor pressure.
Is the partial pressure of a liquid or solid in a closed container measured at equilibrium at a given temperature?
Yes, at equilibrium in a closed container, the partial pressure of a liquid or solid is the pressure exerted by its vapor in the system. This can be measured using techniques like gas chromatography or by using the ideal gas law.
What is the pressure exerted by a vapor confined?
what pressure is exerted by a vapor confined within a given space
In a fluid that is not moving is pressure at a given point exerted equaly in all directions?
Yes, in a fluid at rest, the pressure at a given point is exerted equally in all directions. This is known as Pascal's principle, where the pressure applied to a confined fluid is transmitted undiminished in every direction throughout the fluid.
What is the scientific term for water pressure?
The scientific term for water pressure is hydrostatic pressure, which is the force exerted by a fluid due to its weight and depth. It is defined as the pressure exerted by a fluid at equilibrium at a given point within the fluid, caused by the force of gravity.
How does pressure exerted by a solid object on a surface differ from pressure exerted within a liquid or gas?
In a liquid or gas the pressure at any given point is the same in all directions. In a solid the pressure can vary depending on direction. So, for example, the vertical pressure can be greater or less than the horizontal pressure.
Which term below describes the amount of force exerted on a given area?
Pressure describes the amount of force exerted on a given area.
How do you calculate static head?
unit pressure exerted at any given point within a fluid body resultant from the height of the fluid column
What is the force exerted by air in a given are known as?
Air Pressure
Is true vapor pressure absolute pressure?
No, true vapor pressure is the pressure exerted by a vapor in equilibrium with its condensed phase at a given temperature. Absolute pressure refers to the total pressure within a system, including atmospheric pressure. These two concepts are related but not the same.
What happens to pressure of the force exerted on a given area increases?
The pressure exerted outward by fluids in your body balances the pressure exerted by the atmosphere on the surface of your body. the pressure increases
What is the difference between atmosphere pressure and water pressure?
Atmospheric pressure is the pressure exerted by the weight of the atmosphere above a given point, while water pressure is the force exerted by water on an object or surface due to the depth of the water. Atmospheric pressure decreases with altitude, while water pressure increases with depth.
What is pressure rising?
Pressure rising refers to an increase in the force exerted over a given area within a system. This can occur as a result of various factors such as temperature increase, compression, or addition of a substance. In a closed system, pressure rising can impact the overall performance and stability of the system.
The force exerted on a surface divided by the area over which the force is exerted?
This is the definition of pressure. Pressure is measured in units of force per unit area, such as pounds per square inch (psi) or pascals (Pa). It quantifies how force is distributed over a given area.
