Question

Please Help, I am very grateful!

If an isolated system initially has 50 J of energy, what happens to that amount of energy over time?
The total amount of energy decreases, and it cannot be converted into other forms of energy.
The total amount of energy stays the same, but it can be converted into other forms of energy.
The total amount of energy increases, but it can be converted into other forms of energy.
The total amount of energy decreases, but it can be converted into other forms of energy.

Answer 1

an isolated system initially has 50 J of energy, what happens to that amount of energy over time? The total amount of energy decreases, and it cannot be converted into other forms of energy. The total amount of energy stays the same, but it can be converted into other forms of energy. The total amount of energy increases, but it can be The total amount of energy stays the same, but it can be converted into other forms of energy. This is known as the law of conservation of energy, which states that energy cannot be created or destroyed, only transformed from one form to another. So even though the initial 50 J of energy may be converted into other forms of energy over time, the total amount of energy in the isolated system will remain constant.
