At 80 K, the particles of a gas have
twice the average kinetic energy of the same particles at 40 K
half the average kinetic energy of the same particles at 40 K.
one fourth the average kinetic energy of the same particles at 20 K.
none of the above
Compared with gases, liquids:
have stronger intermolecular attractions.
have more space between their particles.
are much less dense.
are more easily compressed.
At sea level in fair weather, atmospheric pressure is equal to
101.3 kPa.
1 standard atmosphere
760 mm Hg.
all of the above
According to the kinetic theory, gases consist of particles that
occupy considerable volume.
are relatively close together.
exert attractive and repulsive forces on other particles.
have motion that is constant, random, and rapid.
STP refers to:
100°C and 1 atm.
0°C and 1 kPa.
0°C and 1 atm.
100°C and 760 mm Hg.
