MATTER - PROPERTIES AND TRANSFORMATION: Principles Of Chemistry - Gaseous State
What is the standard atmospheric pressure (STP) in Pascals?
101,325 Pa.
100,000 Pa.
1 Pa.
760 Pa.
Which statement best explains Boyle's Law in terms of kinetic theory?
As pressure increases, particles collide more frequently with container walls.
As volume increases, particles have more space, so they move slower.
As temperature increases, particles move faster, increasing volume.
Reducing volume forces gas particles into a smaller space, increasing the frequency of collisions with walls, thus increasing pressure.
The process of 'sublimation' is when a substance changes directly from:
Liquid to gas.
Gas to liquid.
Solid to gas.
Solid to liquid.
A gas occupies 10.0 L at STP. If its pressure is doubled and its absolute temperature is halved, what is its new volume?
2.5 L.
20.0 L.
5.0 L.
10.0 L.
The kinetic energy of gas particles is directly proportional to:
Pressure.
Molar mass.
Volume.
Absolute temperature.
