Answer:
a. Gas pressure: decreases
b. Gas moles: remain constant
c. Average speed of gas molecules: decreases
d. Average distance between molecules: large
Explanation:
The kinetic molecular theory of gases explains the behavior and properties of gases.
In this case, the gas is cooled, so its temperature decreases.
a. Gas pressure:
To analyze the gas pressure we can use the Ideal Gas formula P.V=n.R.T, where pressure and temperature are directly proportional, that is, if the temperature decreases, the gas pressure will also decrease.
b. Gas moles:
The moles of gas remain constant, since the flask is sealed, so gases cannot enter or leave the flask.
c. Average speed of gas molecules:
Temperature is related to the average speed of movement of molecules, so as temperature decreases, the average speed of molecules also decreases.
d. Average distance between molecules:
As the average speed of molecules decreases, they stay in place, hardly moving, so the average distance between molecules is greater than if the molecules were moving faster.
