Air pressure is caused by the density of gas molecules in the air. select the best answer from the choices provided t f

The given statement is true.

Explanation:

Density is defined as mass per unit volume.

Mathematically,      Density =

So, when more is the density of air molecules then it means there will be more mass per unit volume. This will lead to more number of collisions between the molecules. Hence, more will be the air pressure.

Thus, we can conclude that the statement air pressure is caused by the density of gas molecules in the air, is true.

the temperature in kelvin of 2.0 dm3 of an ideal gas is doubled and its pressure is increased by a factor of four. what is the final volume of the gas
