As such, pressure depends on
the amount of gas (in number of molecules), its temperature, and the volume of the container
.
What are the factors on which pressure depends Class 9?
[SOLVED] The factors, on which pressure depend are
surface area
and .
What are the 2 factors that pressure depends on?
(1)It depends on force applied. (2)
Area over in which force acts
. The same force can produce different pressure depending upon area in which it acts. When the force acts over a large area,the pressure produced is less.
What are the two factors on which the pressure in solid depends and how?
The pressure of the solid on the surface depends on
the area of contact
. (b) the area of contact between the two surfaces. The greater the force or the smaller the area the greater the pressure. A man whose mass is 90kg stands on a floor.
Does pressure depend on volume?
More collisions mean more force, so the pressure will increase.
When the volume decreases, the pressure increases
. This shows that the pressure of a gas is inversely proportional to its volume. This is shown by the following equation – which is often called Boyle’s law.
How does pressure depends on force and area?
The same force can produce different pressure depending upon area in which it acts. When the force acts over a large area,the pressure produced is less. The pressure depends on
the number of atoms/molecules in a given space
. we can also say that pressure dependes on force and area.
Why does pressure increase with density?
As shown in the equation, the height of the column isn’t the only thing that affects the pressure, the density of the liquid does too. As
the density of the liquid increases
, so does the pressure. If the liquid is open to the air, there will also be atmospheric pressure on its surface.
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.
How is pressure useful to us?
Pressure is useful to us in the form of atmospheric pressure. It is a force exerted on a surface by the air
above it as gravity pulls it to Earth
. Atmospheric pressure is commonly measured with a barometer.
How do you increase pressure?
- Add more gas. More molecules mean more collisions. …
- Decrease the volume. Less space means less room for the atoms to move in and this will lead to more collisions and more pressure.
- Increase the temperature.
Why does pressure increase with smaller area?
Explanation: 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 do you find density with pressure and height?
P=hρg P = h ρ g
, where P is the pressure, h is the height of the liquid, ρ is the density of the liquid, and g is the acceleration due to gravity.
What are the factors affecting pressure class 8?
- The thrust.
- The area on which the thrust is applied.
- Larger the area on which a thrust acts, less is the pressure exerted by it.
- Larger the thrust acting on an area more is the pressure exerted on it.
Why does pressure not depend on volume?
The derivation of pressure as a measure of energy per unit volume from its definition as force per unit area is given in. … The pressure exerted by a static liquid depends only on
the depth, density of the liquid
, and the acceleration due to gravity.
Does water volume increase pressure?
As you go deeper into a body of water, there is more water above, and therefore a greater weight pushing down. This is the reason water
pressure increases with depth
. The pressure depends only upon the depth, and is the same anywhere at a given depth and in every direction.
Does more volume equal more pressure?
Volume is inversely proportional to pressure
, if the number of particles and the temperature are constant. There are two ways for the pressure to remain the same as the volume increases. … So if the number of particles and the pressure are constant, temperature is proportional to the volume.
