Answer:
See explanation
Explanation:
Temperature is defined as a measure of the average kinetic energy of the molecules of a body.
When a substance is heated, the kinetic energy of its molecules increases as the temperature increases; hence the particles of the substance moves faster with increasing temperature.
When heat is withdrawn from a liquid, the temperature decreases and the average kinetic energy of the molecules decreases. The molecules become less energetic hence the liquid changes into solid
The reaction that would beat represent a typical reaction mechanism is when A and B react with each other to produce certain products.
Answer:
B. Charges ( a slight positive charge on one end, and a slight negative charge on the other).
