What is 1 atm equal to in torr

760 torr

What is 1 atm equal to in Pascal (Pa)

101,325 Pa

How many Pa are equal to 1 kPa?

1 kPa = 1000=10³ Pa

What is 1 atm equal to in bar?

1.01325 bar

How many bar are equal to 1 mbarr?

1 mbar = 0.001/10⁻³ bar

What is 1 atm equal to in lb/in² psi

14.696 lb/in² psi

What is Boyle's Law?

P₁V₁=P₂V₂

What does Boyle's Law mean?

Pressure is inversely proportional to volume (P∝1/V; P↑V↓)

What is Charles' Law?

V₁/T₁=V₂/T₂

What does Charles' Law mean?

Volume is proportional to temperature (V∝T; V↑T↑)

What is the conversion equation from C to K

C + 273 = K

Why should you only use Kelvin?

It is used to avoid negative numbers causing to mess up equations.

What is the ideal gas equation?

PV=nRT

What does R mean in the ideal gas equation?

R is a gas constant;

R = 0.08206 L x atm/mol x K

What does n mean in the ideal gas equation?

n = number of moles

What is the Gas density equation?

P(MM) = dRT

What is Dalton's law of partial pressure?

Ptotal = (n₁+n₂+..)RT/V= ntoalRT/V

What does Avogadro's hypothesis state?

equal volumes of gases under the same conditions of temperature and pressure have equal numbers of particles

What is the kinetic molecular theory?

Heavier gasses move slower than lighter gasses

What is the velocity of gas particles?

m₁v₁²=m₂v₂²

√m₁m₂² =v₂/v₁

What is the combined gas law?

P₁V₁/T₁ = P₂V₂/T₂
