Question

.
Which variable is focused on when working with gas laws? (Choose all that apply)
Pressure
Volume
Density
Temperature

Answer 1

Answer:

Pressure, volume and temperature

Explanation:

Ideal gas law

$\boxed{pV=nRT}$

where

p= pressure,

V= volume,

n= number of moles,

R= universal gas constant

T= temperature

_____

The ideal gas law is made up of the 4 laws below:

1) Avogadro's law

• The volume of a sample of gas is directly proportional to the number of moles of gas in the sample at constant temperature and pressure

• V∝ n

2) Boyle's law

• The volume of a fixed mass of gas is inversely proportional to its pressure at constant temperature

• p∝ 1/V

3) Charles' Law

• The volume of gas is directly proportional to its absolute temperature at constant pressure

• V∝ T

4) Gay-Lussac's Law

• The pressure of gas is directly proportional to its absolute temperature at constant volume

• p∝ T
