Question

Can someone explain the gas laws?

Answer 1

Explanation:

Use the Ideal Gas Law:

PV = nRT

where P is absolute pressure,

V is volume,

n is number of moles,

R is the universal gas constant,

and T is absolute temperature.

First, identify which variables in the problem are constant (note that R is always a constant).

Next, solve for the constants and use that equation to write a proportion.

Finally, plug in the given values and solve for the unknown variable.

For example, if n and R are the constants:

nR = PV/T

Therefore:

P₁V₁/T₁ = P₂V₂/T₂
