What do you know about the law of conservation of energy? Check all the statements that are true according to this law.

• The total amount of mass in a system remains constant regardless of the changes that take place in that system.

• Energy is neither created or destroyed; it only changes form.

• 
• 
• In a closed system, i.e., a system that isolated from its surroundings, the total energy of the system is conserved.
