Question

2. A sample of an ideal gas at 0.93atm and 25°C occupied a volume of 17.3L. This gas was transferred to a 3.7L container without a temperature change. What was by the pressure of the gas under the new conditions? tog 259 10 Bluz A Wanita Indº

Answer 1

2. From Boyle's law,

P1 x V1 = P2 x V2

Given that, P1 = 0.93 atm

V1 = 17.3 L, P2 = ? , V2 = 3.7 L

=> 0.93 atm x 17.3 L = P2 x 3.7 L

=> P2 = final pressure = 4.35 atm

1.

a. Gases consist of a large number of molecules which are in continuous and random motion.

b. The volume of the gas molecules is negligible when compared with the volume of container of the gas.

c. Attractive and repulsive forces between gas molecules are negligible.

d. Energy can be transferred between molecules during collisions, but the average kinetic energy of the molecules doesnot change with time as long as the temperature of the gas remains constant.

e. The average kinetic energy of a molecule is proportional to the Kelvin temperature.
