Explain its significance. Check all that apply. Check all that apply. In chemical and physical processes, matter exchanges energy either as heat or work or both with the surroundings. Systems with high potential energy tend to change in the direction of lower potential energy, releasing energy into the surroundings. In the exchanges, the total energy is always changed; energy is created and destroyed. In the exchanges, the total energy is always conserved; energy is neither created nor destroyed. Systems with low potential energy tend to change in the direction of higher potential energy, releasing energy into the surroundings. In only physical changes, matter exchanges energy with its surroundings.

The question is incomplete. Here is the complete question.

Explain the significance of the Law of Conservationof Energy. Check all that apply.

1) In chemical and physical processes, matter often exchange energy with its surrounding.

2) System with low potential energy tend to change in the direction of higher potential energy, releasing energy into the surroundings.

3) In the exchanges, the total energy is always conserved; energy is neither created nor destroyed.

4) In chemical and physical changes, matter never exchange energy with its surroundings.  

5) In the exchanges, the total energy is always changed; energy is created and destroyed.

6) Systems with high potential energy tend to change in the direction of lower potential energy, releasing energy into its surroundings.

Answer and Explanation: Law of Conservation of Energy states that total energy is constant in any process. It may change in form or be transferred from one system to another, but the total remains the same.

So, analysing each statement above, we have:

In chemical and physical processes, matter CAN exchange energy with its surroundings, so first and fourth statements are incorrect.

Systems with higher potential energy tend to change in the direction of lower potential energy, and can release energy into its surroundings, so sixth statement is correct.

As cited above, in exchanges, total energy is always conserved, i.e. it is always constant, which means inside the system, energy is being transformed into another type of energy or transferred to other matter. Fifth statement is correct.

answer: the correct answer is   air pressure at the top of mount everest is higher than at the bottom of the grand canyon.
