MATTER - PROPERTIES AND TRANSFORMATION: Principles Of Chemistry - Gaseous State
Charles' Law states that for a fixed mass of gas at constant pressure, the volume is:
Directly proportional to its absolute temperature (in Kelvin).
Independent of its temperature.
Inversely proportional to its temperature (in Celsius).
Directly proportional to its temperature (in Celsius).
A gas occupies 2.0 L at 200 K. What is its volume at 400 K if the pressure remains constant?
4.0 L.
1.0 L.
8.0 L.
2.0 L.
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 gas particles collide less frequently with the container walls.
The number of gas particles increases.
The volume of the gas particles themselves increases.
A gas is contained in a flexible balloon. If the balloon is placed in a refrigerator, its volume decreases. This illustrates:
Combined Gas Law.
Charles' Law.
Boyle's Law.
Graham's Law.
Diffusion is the process by which particles:
Stick together to form larger clumps.
Move from a region of lower concentration to a region of higher concentration.
Settle at the bottom of a container.
Move from a region of higher concentration to a region of lower concentration.
