What temperature is required for 0.0470 mol of gas to fill a balloon to 1.20 L under .998 atm pressure?

Back

307 K

Front

What is Charles' Law?

Back

V₁ / T₁ = V₂ / T₂

Front

What does Boyle's Law state?

Back

P₁V₁ = P₂V₂ (at constant temperature).

Front

What is the ideal gas law formula?

Back

PV = nRT.

Front

Define absolute zero in terms of temperature.

Back

Absolute zero is 0 K, the point at which molecular motion stops.

Front

What is the relationship between pressure and volume in Boyle's Law?

Back

Pressure increases as volume decreases, and vice versa.

Front

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

Back

The volume increases (Charles' Law).
