relative weight of Mg3N2 = (3x24)+(2x14) = 100 g/mole
mole of Mg3N2 = 10,3 g/100 g/mole = 0,103 mole
mole of NH3(g) = 2/1 x 0,103 mole = 0,206 mole
volume NH3(g) which collected at STP = mole NH3(g) x 22,4 litre/mole = 0,206 mole x 22,4 litre/mole = 4,6144 litre.

F = +32
Enter the temperature into the degrees Celsius (C) equal to 113∘ Fahrenheit (F). The formula F = 1.8°C + 32 allows you to find the Fahrenheit (F) temperature for a given Celsius (C) temperature.
Given: C = (F - 32)
First, multiply both sides by to get:
= F - 32
Add 32 to both sides and transpose to get:
F = + 32
These are the formulas to translate between Fahrenheit and Celsius temperatures.
Fahrenheit and Celsius meet at −40 degrees.
That is −40∘ F = −40∘C
So alternative formulas for the conversions can be written:
F = (C + 40) − 40
C = (F +40) − 40

Answers
With an increase in the kinetic energy of the solid molecule the intermolecular bonds become weaker, temperature increases, melting and molecules vibrating faster are changes.
What is the effect of the increased kinetic energy?
Kinetic energy is the form of the energy that is present in an entity in motion. When the kinetic energy is increased then the temperature of the particles increases and leads to evaporation.
The increased kinetic energy weakens the intermolecular bonds of the liquid particles and the molecules of the particles start vibrating fast.
Therefore, option b. intermolecular bonds become weak, option e. evaporation, option f. temperature increases and option h. molecules vibrate faster are the changes.

Final answer:
The changes that increase the kinetic energy of liquid particles are B, E, F, and H which correspond to evaporation, temperature increases, and molecules vibrating faster.
Explanation:
The changes that would be accompanied by an increase of the kinetic energy of particles in a liquid are evaporation, temperature increases, and molecules vibrate faster. During evaporation, molecules gain sufficient energy to overcome intermolecular forces and enter the gaseous phase. When the temperature increases, the average kinetic energy of the molecules increases, causing them to vibrate faster. Consequently, the correct answer is B, E, F, and H.
The changes that would be accompanied by an increase of the kinetic energy of particles in a liquid are B, E, F, and G.
When temperature increases, the average kinetic energy of the particles in a liquid also increases. This is represented by changes B and F. Evaporation (change E) also leads to an increase in the kinetic energy of the particles as they gain enough energy to escape into the vapor phase. Lastly, intermolecular bonds becoming weaker (change G) allows for more movement of the particles, increasing their kinetic energy.
