If the gas is confined by volume then the temperature must decrease. Given by the ideal gas equation pv=nrt on the left pressure time volume. If the volume is constant then the decrease in value of the left hand side of the equation has to compensated by a change in the right hand side. n= no of moles (a measure of the number of atoms present) R= gas constant so the only variable is T temperature which must decrease

There can be three possible causes of an increase in the pressure of a confined gas:

-- More gas is pumped in.

-- The temperature inside the container is increased.

-- The volume of the container is reduced, as with a piston.

Describe the changes in gas pressure?

The increase in solubility causes increase in pressure.


Which of the changes would not cause an increase in the pressure of a contained gas?

The volume of the container is increased.


What causes a pressure in a gas?

Heat. The addition of heat causes expansion and spreading of the molecules which in turn causes an increase in pressure.

How does increasing the number of particles of a contained gas it's pressure?

Pressure is defined as the force per unit area applied. This force is derived from the collision of particles. Pressure increase when this force is increase, and it applies otherwise too. By increasing the number of particles in a specific amount of gas, there are more particles colliding onto the container. This causes the force per unit exerted by the gas on the container to increase. As such, when one increases the number of particles within a container of gas, the pressure within the container will increase.


What would cause the pressure in a sealed container of gas to increase?

temperature increase The pressure of a contained sample of gas can be increased by increasing its temperature, or by decreasing its volume, or by injecting additional mass into it.


What happens to pressure when gas expands?

If the gas is contained at a constant volume, the pressure increases. If the gas is not contained, the pressure remains the same or drops.


How will a pressure increase affect a gaseous system?

According to Boyle's Law of Pressure-Volume Relationship, an increase in the pressure of a gas will decrease it's volume. And according to Charles's Law of Temperature-Pressure Relationship, an increase in pressure causes an increase in temperature.


Is the pressure of contained neon gas increases as more gas is added to the container a chemical change?

Increased pressure is a physical change, not a chemical change - even if the increase in pressure is itself the result of a chemical process.


How does gas affected when air is heated?

If the question is "How IS gas affected when it is heated":When gas is heated, it's volume increases (it expands).If the gas is contained within a chamber, the pressure will increase instead.


How is the pressure affected by the collision of gas particles?

The more the collisons the higher the pressure, the lesser amount of collisons the lower the pressure.
