Answer:
1) they represent the volume of the system
2) The pressure referred to in Boyle's law is the pressure the gas exerts on the container.
3) pressure is increased
4) temperature
5) the volume in the second cylinder will be half of the volume of the first cylinder
6) pressure
7) the volume of the second cylinder will be three times the volume of the first cylinder.
8)PV/T = k
9)the volume remains constant
Explanation:
Pressure is defined as force per unit area in science. Pressure of a gas as defined in the gas laws refer to the pressure the gas molecules exert on the walls of the container as they frequently collide with it in accordance with the kinetic theory of gases. The kinetic theory of gases states that gas molecules are in constant motion and collide frequently with each other and the walls of the container.
Boyle's law states that the volume of a given mass of gas is inversely proportional to its pressure at constant temperature. Hence when volume decreases, pressure increases accordingly.
Charles law states that, the volume of a given mass of gas is directly proportional to it's temperature (in Kelvin) at constant pressure.
To maintain a constant pressure, volume and temperature must increase concurrently to the same degree. Hence the application of Charles law.
PV/T = k
Hence;
P1V1/T1= P2V2/T2
P1= P
T1= T
V1= 100cm^3
V2= ??
P2= 2P
T2 = 2T
From
P1V1/T1= P2V2/T2
P1V1T2 = P2V2T1
V2 = P1V1T2/ P2T1
V2 = P ×100 ×2T/ 2P × T = 200PT/2PT
V2= 100cm^3
Hence the volume remains constant
