(B) force applied.
(C) its temperature.
(D) its area.

Answer 1

Answer:

It's volume

Explanation:

Pressure = force/ area = (force x length/ volume). An increase in pressure means increase in force, which increases the motion of the gas particles in the fixed area of the container. Particles now collide more frequently and thereby, the temperature of the gas increases. Thus, a change in pressure on an confined gas results in the change in its volume, area and temperature. Whereas, weight is given by 'mg' which does not change with change in pressure as the mass of the gas and acceleration due to gravity remains constant.

Answer 2

Hope it helps :)

Explanation:

LPG Pressure Varies with Temperature  

When LPG is stored in a gas bottle, it is under pressure.  

The term “pressure” refers to the average force per unit of area that the gas exerts on the inside walls of the gas bottle.

Pressure is measured in kilopascals (kPa) or pounds per square inch (psi).  

“Bar” is yet another unit of measure for pressure.  

1 Bar = 100 kPa, so it is metric based but not an SI unit of measure.  

LPG pressure can vary greatly based on temperature, as shown in the chart.  

The level of fill in the gas bottle comes into play when the LPG is being used, as it affects the rate of vapourisation.  

As LPG is a liquefied gas, the pressure inside the cylinder will remain the same from full until the last of the liquid LPG is vapourised.  

Then the pressure will fall quickly as the last of the LPG vapour is used, as well.
