Gas Laws

Question 1

State Boyle’s Law.

Answer 1

When the temperature is constant, the volume of a given mass of dry gas in inversely proportional to its pressure.

Question 2

State Charles’ Law.

Answer 2

When the pressure remains constant, the volume of a given mass of dry gas is directly proportional to its absolute temperature.
OR
Pressure remaining constant, the volume of a given mass of dry gas increases or decreases by 1/273 of its original volume at 0 degrees Celsius for each degree c rise or fall in temperature.

Question 3

What unit is normally used for numericals?

Answer 3

K. It should always be converted from Celsius.

Question 4

What is a gas equation?

Answer 4

Equation used in chemical calculations for calculating the change in volumes of gases when pressure and temperature both undergo a change thereby giving a simultaneous effect of changes of temperature and pressure on the volume of a given mass of dry gas.
