Solution Steps

Step 1: Understanding the Law of Energy and Mass Conservation

The law of energy and mass conservation, also known as the first law of thermodynamics, states that the total amount of energy and mass in an isolated system remains constant. This means that energy and matter cannot be created or destroyed, only transformed from one form to another.

Step 2: Analyzing the Options
  1. Both energy and matter can be created and destroyed.
  2. Energy can be created and matter destroyed.
  3. Energy cannot be destroyed but matter can be created.
  4. Energy and matter cannot be created or destroyed.
Step 3: Selecting the Correct Option

Based on the law of energy and mass conservation, the correct statement is that energy and matter cannot be created or destroyed.

Final Answer

\(\boxed{\text{4) energy and matter cannot be created or destroyed.}}\)
