Ch.3 States of Matter (Physical)

Front

What happens to the motion of gas particles when they collide?

Back

The motion of one particle of a gas is affected by the motion of other particles only when they collide.

Front

What causes gas pressure in a closed container?

Back

Gas pressure is caused by the collisions of gas particles, such as helium atoms, with the walls of the container.

Front

What is the state of matter that exists only at extremely low temperatures?

Back

The state of matter that exists only at extremely low temperatures is called a Bose-Einstein condensate.

Front

What percentage of observable matter in the universe exists as plasmas?

Back

Ninety-nine percent of all the matter that can be observed in the universe exists as plasmas.

Front

What effect does lowering the temperature have on gas pressure in a closed container?

Back

Lowering the temperature in a closed container will cause a decrease in gas pressure.

Front

Define 'gas pressure'.

Back

Gas pressure is the force exerted by gas particles colliding with the surfaces of their container.

Front

What is a Bose-Einstein condensate?

Back

A Bose-Einstein condensate is a state of matter formed at temperatures close to absolute zero, where particles occupy the same quantum state.

Front

What are the four fundamental states of matter?

Back

The four fundamental states of matter are solid, liquid, gas, and plasma.

Front

How does temperature affect the kinetic energy of gas particles?

Back

As temperature increases, the kinetic energy of gas particles increases, leading to more vigorous motion.

Front

What is the relationship between gas volume and pressure in a closed system?

Back

According to Boyle's Law, the volume of a gas is inversely proportional to its pressure in a closed system at constant temperature.
