C. Lowering the temperature
At the lower temperature, particles have less kinetic energy, so they move slower.
I believe the answer is C because the first two are mechanical hazards and C mentions plug which is electrical.
Answer:
Nitrogen molecule is 28 neuclons×1.67×10-27 kg/nucleon = 4.68 д 10-26 kg. So the average speed of a gas molecule is about 500 m/sec. This is roughly the speed of sound in a gas 340 m/sec. So the average kinetic energy of the gas molecules is related to the temperature of the gas.
I hope this is helpful
