particles - gas laws

Question 1

what is boyle’s law

Answer 1

1680 - the pressure of a gas is inversely proportional to its volume
assuming temp remains constant

Question 2

explain boyle’s law

Answer 2

• as air is pumped into a system, the pressure increases
• this forces the liquid level in column to rise, compressing gas trapped at the top
• doubling the pressure causes the volume of the air to halve

Question 3

equation for boyle’s law

Answer 3

p ∝1 ÷ V
pressure x volume = a constant
P1V1 = P2V2

Question 4

what is charles’ law

Answer 4

1780 - the volume of a gas is directly proportional to its thermodynamic temperature
assuming pressure stays constant

Question 5

explain charles’ law

Answer 5

gasses occupy a greater volume when at a higher temperature (+ kinetic energy)
–> they collide and push away from each other more often

Question 6

equation for charles’ law

Answer 6

V ∝T
V1/T1 = V2/T2

Question 7

what is gay-lussac’s law

Answer 7

1808 - pressure of a gas is directly proportional to its thermodynamic temperature
assuming volume stays constant

Question 8

explain gay-lussac’s law

Answer 8

as temperature rises, the particles in the gas gain more kinetic energy - more collisions - increasing pressure of gas

Question 9

equation for gay-lussac’s law

Answer 9

p ∝T
