chemical change
The activation energy.
That is officially called the activation energy.
Yes.
for a state change to happen it must lose or gain or loose kinetic energy
yes
yes, enthalpy change take place when a bond is either form or break
Endothermic reactions require energy to be absorbed in order to take place. This means that the reactions absorb heat from their surroundings in order to proceed.
No, a change in matter can't take place without energy being released or absorbed? Why? Well, this is because every chemical or physical change in matter includes a change in energy. You can't change matter without a change in energy. Energy is the ability to do work or cause change. Hope you find this helpful. And yes, this answer has been approved by my science teacher.
A sufficient amount of activation energy is needed.
The liquid will boil.
You may need to restart your computer. At times, when you make changes, your computer needs to be restarted before the changes will take place.?æ
