what happens to gas molecules as the pressure is increased while the temperature and volume of the container remain constant acc
aleksandrvk [35]

Answer:

According to the kinetic molecular theory of gases, the average speed and kinetic energy of gas molecules would INCREASE.

Explanation:

In the kinetic molecular theory of gases, assumptions were made based on macroscopic properties of gas (pressure, volume and temperature) which are as a result of the microscopic properties like the position and the speed of the gas molecules. The kinetic molecular theory explains the behaviour of gases through the following 5 assumptions made about an ideal gas;

--> Molecules of a gas are in constant and rapid motion in straight lines until they collide with one another and with the walls of their containers.

--> The actual volume occupied by the had is negligible compared with the volume of the container.

--> Forces of attraction or repulsion between the molecules of a gas are negligible

--> The collision between the molecules is perfectly elastic.

--> The average kinetic energy of the gas molecules is proportional to the temperature of the gas.

Because gas molecules are in constant motion, it has kinetic energy which can be altered when there is increase in pressure. An increase in pressure will cause gas molecules to collide more frequently with one another. This in turn leads to increase in average speed and the kinetic energy of the individual molecules.

When warmed with an ammonium salt ammonia gas is given off
Elanso [62]

The ways in which ammonia can be identified is mentioned in below pointers.

<h3>What is Ammonia ?</h3>

Ammonia is a compound of nitrogen and hydrogen with the formula NH3.

A stable binary hydride, and the simplest pnictogen hydride.

Ammonia is a colourless gas with a distinct pungent smell.

Biologically, it is a common nitrogenous waste,

Three ways in which ammonia gas can be identified is:

  • It has a sharp characteristic odor.

  • When a glass rod dipped in HCl is brought in contact with the gas white color fumes of ammonium chloride are formed.

  • It turns moist red litmus blue, moist turmeric paper brown, and phenolphthalein solution pink.
