what best describes the energy in a closed system at the beginning of a day and the energy at the end of the same day? check all that apply.\n□ some energy can disappear after it has caused motion.\n□ some energy can be changed from one form to another.\n□ some energy can be lost to the environment around the system.\n□ the total initial energy will be equal to the total final energy.\n□ the total initial energy will be greater than the total final energy.\n□ friction can cause energy to be destroyed during the day.\n□ friction can cause the amount of thermal energy to increase.

Answer

Answer:

  • Some energy can be changed from one form to another.
  • The total initial energy will be equal to the total final energy.
  • Friction can cause the amount of thermal energy to increase.

Brief Explanations:

In a closed - system, energy is conserved (total initial = total final). Energy can change forms (e.g., mechanical to thermal). Friction converts mechanical energy to thermal energy, increasing thermal energy. Energy cannot be destroyed or disappear in a closed - system, and no energy is lost to the environment as it's a closed - system.
