Gases Intro

Front

What is the behavior of gas molecules?

Back

Gas molecules are in constant and random motion.

Front

Why do astronauts wear full-body space suits?

Back

Any exposed area would potentially explode due to lack of atmospheric pressure.

Front

What affects the kinetic energy of gas particles?

Back

The temperature of the container greatly affects the kinetic energy of gas particles.

Front

How do you convert Celsius to Kelvin?

Back

To convert Celsius to Kelvin, add 273.15 to the Celsius temperature.

Front

What happens to the volume of a gas when temperature increases?

Back

When temperature increases, the volume of the gas also increases.

Front

Define gas pressure.

Back

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

Front

What is the relationship between temperature and kinetic energy in gases?

Back

As temperature increases, the kinetic energy of gas particles increases.

Front

What is the ideal gas law?

Back

The ideal gas law is PV=nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature in Kelvin.

Front

What is the significance of absolute zero?

Back

Absolute zero (0 K) is the theoretical temperature at which gas particles have minimum kinetic energy.

Front

What happens to gas volume when pressure increases?

Back

According to Boyle's Law, if pressure increases, the volume of the gas decreases, assuming temperature is constant.
