Answer:velocity of molecules within a body
Explanation:
Temperature is defined as the average kinetic energy of the molecules of a body. The kinetic energy of a body depends on the velocity of the molecules of the body. When the temperature of a body increases, its particles acquire greater kinetic energy and move at higher velocity. Hence temperature depends on the velocity of the molecules of a body while heat is a form of energy.
Yes they will need to worry cause the chemicals could spread in the water making it explode and kill animals and it would be very bad
Answer: Adding or removing energy from matter
