Gas Laws

The law that gives the relation between temperature and pressure is:

• Boyle's Law

• Ideal Gas Law

• Charles' Law

The value of standard pressure is:

• 760 mm

• 76 mm

• 760 cm

The mathematical expression of Charles' Law is:

At absolute zero:

• the theoretical pressure is zero

• the temperature is 0˚C

• the theoretical volume is zero

If the pressure is doubled for a gas, then its volume:

• halves

• doubles

• remains the same

The mathematical expression for gas equation is:

• P/T = constant

• PV= constant

• PV/T = constant

I L =

• 100 cm³

• 1000 ml³

• 1 dm³

'Pressure remaining constant, the volume of a given mass of dry gas is directly proportional to its absolute temperature.' This is:

• Charles' law

• Boyle's Law

• Ideal gas Law

38°C=

• (38 – 273) K

• (38 + 273) K

• (38 * 273) K

The boiling point of water is:

• 100 K

• 373 K

• 0 K
