What happens when a substance is heated?

The atoms/molecules gain energy and move faster.

What is the relationship between temperature and the speed of atoms/molecules?

Temperature is a measurement of the average speed of atoms/molecules.

What happens to the volume of a substance when it is cooled?

The volume decreases as the atoms/molecules get closer together.

How do the collisions of atoms/molecules change when a substance is warmed?

The collisions become stronger and more frequent.

What is the relationship between temperature and the movement of atoms/molecules?

Higher temperature means the atoms/molecules are moving faster.

An increase in the number density of gas particles will result in higher pressure.


In a gas, the mean free path decreases as the pressure increases.


Gaseous particles move slower and collide less frequently as the temperature increases.


At low pressures, like those found in outer space, the mean free path of gas particles is typically small.


The ideal gas law is not relevant for describing the relationship between the number density of gas particles and pressure.


Gases exhibit an increase in viscosity with increasing temperature.


In gases, diffusion occurs at a slower rate compared to liquids.


Intermolecular forces have no role in determining the behavior of gaseous particles.


Hydrogen bonding does not lead to unique behaviors in gases.


Gaseous particles cannot interact with electromagnetic radiation.


Test your knowledge on heat transfer and temperature measurement. Learn about how energy is transferred to substances, resulting in changes in the speed of atoms and molecules, which are detected as changes in temperature.
