MATTER - PROPERTIES AND TRANSFORMATION: Principles Of Chemistry - Gaseous State
If the temperature of a gas is increased while its volume is kept constant, the pressure of the gas increases because:
The gas particles move faster and hit the container walls with more force and frequency.
The volume of the gas particles themselves increases.
The number of gas particles increases.
The gas particles collide less frequently with the container walls.
A gas is contained in a flexible balloon. If the balloon is placed in a refrigerator, its volume decreases. This illustrates:
Graham's Law.
Charles' Law.
Combined Gas Law.
Boyle's Law.
What is the effect of increasing temperature on the rate of diffusion of gases?
It has no effect on the rate of diffusion.
It stops diffusion completely.
It increases the rate of diffusion.
It decreases the rate of diffusion.
Which of the following explains why a sealed bag of potato chips puffs up when carried from sea level to a high altitude?
Temperature decreases at higher altitude.
More oxygen is available at higher altitude.
The gas inside the bag expands due to lower gravity.
Atmospheric pressure decreases at higher altitude.
A substance has a very low molar enthalpy of evaporation. This suggests that its particles are held together by:
Weak intermolecular forces.
Strong covalent bonds.
Strong metallic bonds.
Strong ionic bonds.
