How does pressure exerted by a solid object on a surface differ from pressure exerted within a liquid or a gas?
The pressure exerted by a solid object is in only one direction.
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.
What is ferrostatic pressure?
The pressure exerted by the pressure head of liquid steel in a container at bottom surface of the container is known as ferro static pressure.
When vapor pressure equals atmospheric pressure at the surface of a liquid it has reached its what?
When the vapor pressure equals atmospheric pressure at the surface of a liquid, it has reached its boiling point. This is the temperature at which the vapor pressure of the liquid is equal to the pressure exerted on it by the surrounding atmosphere, causing the liquid to change into vapor.
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.
What are the factors on which pressure exerted by liquids depends?
The pressure exerted by liquids depends on the depth of the liquid, the density of the liquid, and the acceleration due to gravity. The pressure increases with depth due to the weight of the liquid above, and it is also influenced by the density of the liquid.
What causes particals to evaporate and leave the surface of a liquid?
Molecules at the surface of a liquid absorb kinetic energy (kinetic energy used to disrupt intermolecular forces) and evaporate. (vapor pressure is exerted)
When liquid material exerts a pressure or force in which direction?
Liquid material exerts pressure equally in all directions, following Pascal's Principle. This means the pressure is exerted perpendicular to any surface it comes into contact with, resulting in a uniform distribution of force.
What happens to the boiling point of a liquid if the pressure exerted on a surface is reduced?
The boiling point of a liquid decreases when the pressure is reduced. This is because lower pressure results in less resistance for the liquid molecules to escape into the gas phase, causing them to boil at a lower temperature.
How does pressure exerted by a liquid increase with depth?
It increases linearly, assuming the liquid is incompressible.
How does the pressure exerted by a liquid vary with direction and depth?
The pressure exerted by a liquid increases with depth. This is known as hydrostatic pressure and is directly proportional to the density of the liquid. The pressure variation with direction is isotropic, meaning it is the same regardless of the direction taken in the liquid.
What kind of pressure of a liquid is the pressure exerted at equilibrium and is dependent on temperature only?
Vapour pressure ; yes
