Gay-Lussac’s Law

Question 1

Gay Lussac’s Law

Answer 1

The pressure of a fixed quantity of gas is directly proportional to the temperature in Kelvin if the volume of gas is kept constant

Question 2

Equation and formula

Answer 2

EQUATION: P1/T1 = k

FORMULA: P1/T1 = P2/T2

Question 3

What happens if the temperature doubles or halves

Answer 3

If temp doubles, pressure also doubles

If temp halves, pressure also halves

Question 4

Deviation of gases at low temperatures

Answer 4

• at low temp, kinetic energy decreases and thus also the speed
• the molecules move closer together and thus a stronger force of attraction
• the gas liquifies
• the pressure between the gas molecules is less than what gas laws predict
• the volume of a real gas are greater than predicted for an ideal gas

Question 5

STP

Answer 5

• standard temp = 273K

- standard pressure = 101,3kPa
