In gases, pressure is
directly proportional to volume
inversely proportional to volume
directly proportional to friction
inversely proportional to heat
For a constant temperature, Boyle's law states that
the pressure of a fixed amount of gas is directly proportional to the volume of the gas
the pressure of a fixed amount of gas is inversely proportional to the volume of the gas
the pressure of a fixed amount of gas is independent of the volume of the gas
None of the above
For an ideal gas, incorrect statement is
Molecules do not occupy any space
No attractive force exist between the molecules
The gas molecules move in random, straight line motion
None of the mentioned
Correct statement is
Gases at low pressure or high temperature behave as an ideal gas
Gases at high pressure or low temperature behave as an ideal gas
Gases at high density behave as an ideal gas
None of the mentioned
According to Charles Law, if you have a balloon inside a car at noon during a hot summer day the balloon molecules inside will increase in pressure.
True
False
Gas pressure is caused by
Gas molecules heating up
Gas molecules reacting with other gas molecules
Gas molecules hitting the walls of a container
Gas molecules hitting other gas molecules
Cooking gas containers are kept in a lorry moving with uniform speed. The temperature of the gas molecules inside will
Increase
Decrease
Remain the same
Decreases for some, while increase for others
At Boyle’s temperature
Joule’s effect is positive
Van der Waal’s equation becomes zero
Gases obey Boyle’s law
Water solidifies
For Boyle’s law to hold good, the gas should be
Perfect and of constant mass and temperature
Real and of constant mass and temperature
Perfect and at constant temperature but variable mass
Real and at constant temperature but variable mass
The temperature of gas is held constant, while its volume is decreased. The pressure exerted by the gas on the wall of the container increases, because its molecules
Strike the walls with higher velocities
Strike the walls with large farce
Strike the walls more frequently
Are in contact with the walls for a shorter time
