Honors chem kinetic molecular theory w/out 2.1

Diffusion

Particles spreading out from a crowded area to a less crowded area.

Pressure

Force from something pushing on a surface.

Manometer

A tool that measures the pressure of a gas inside a container.

Barometer

A tool that measures the pressure of the atmosphere.

Temperature

A measure of how hot or cold something is.

Thermal Expansion

When an object gets bigger as it gets hotter.

Absolute Temperature

Temperature measured starting from absolute zero.

Absolute Zero

The coldest possible temperature, where all atoms stop moving.

Standard Temperature and Pressure (STP)

A fixed set of temperature and pressure conditions used to compare gases.

Kinetic Molecular Theory

The idea that gas particles are constantly moving and colliding with each other.

What happens to the alcohol level in a thermometer when it is placed in warm liquid?

The alcohol level rises.

What is the boiling point of water on the Celsius scale?

100 degrees Celsius.

What pressure is indicated at sea level?

1 atm or 101.3 kPa.

How does temperature affect volume according to gas laws?

As temperature increases, volume increases.

How does temperature affect pressure according to gas laws?

As temperature increases, pressure increases.

What happens to pressure as the volume increases?

Pressure decreases.

What is the relationship between the number of particles and pressure?

As the number of particles increases, pressure increases.

How does atmospheric pressure affect mercury in a barometer?

Atmospheric pressure pushes mercury up into the tube.
