A hypothetical gas that perfectly fits all the assumptions of the kinetic-molecular theory is known as
a real gas.
an ideal gas.
an imaginary gas.
a perfect gas.
Which of the following is an assumption of the kinetic-molecular theory of gases?
Collisions between gas particles are inelastic.
Gases consist of closely spaced particles.
Gas particles move around in an orderly manner.
The temperature of a gas depends on the average kinetic energy of the gas particles.
A liquid can be described as a form of matter that
has a definite volume.
has a definite shape.
cannot diffuse.
has low density.
Diffusion is much slower in liquids than in gases because
liquids exist at lower temperatures.
liquid particles are closer together.
liquid particles weigh more.
liquids have surface tension.
The three states of matter of a particular substance, in order of the strength of intermolecular forces from least to greatest, are
solid, liquid, gas
liquid, solid, gas
gas, liquid, solid
gas, solid, liquid
Which is an example of a noncrystalline solid?
emerald
quartz
ice
glass
The process of changing from a solid to a gas is known as
condensation.
sublimation.
deposition.
vaporization.
The point on a phase diagram that indicates the temperature and pressure conditions at which the solid, liquid, and vapor of the substance can coexist at equilibrium is known as the
critical point.
phase point.
triple point.
equilibrium point.
If water molecules were not linked by hydrogen bonds to form groups in liquid water, what would be the physical state of water at room temperature?
solid
liquid
gas
a mixture of liquid and gas
Which substance is important in moderating Earth's climate because it occurs frequently in all three states?
water
carbon dioxide
nitrogen
chlorophyll
