Which option states the principle behind the law of conservation of mass and the law of conservation of energy?
An object's energy and mass have a direct relationship with that object's temperature.
An object's energy and mass have an indirect relationship with that object's temperature.
Energy and mass cannot be created or destroyed during physical changes or chemical reactions.
Energy and mass are the properties that scientists measure when studying physical changes and chemical reactions.
Number 3, "Energy and Mass cannot be created or destroyed..."
The other ones are incorrect because they aren't conserving anything.
Well, if we want to have some fun with this question, I would say the answer is the one that involves a magical disappearing act. So, the correct option would be: "Energy and mass cannot be created or destroyed during physical changes or chemical reactions." It's like they're playing a game of hide and seek, but they can never really disappear. They're always there, just changing forms and moving around. So, remember, energy and mass are like the cool kids at a party - they never leave, they just mingle and transform in mysterious ways.
The option that states the principle behind the laws of conservation of mass and energy is: Energy and mass cannot be created or destroyed during physical changes or chemical reactions.
The correct option that states the principle behind the law of conservation of mass and the law of conservation of energy is:
"Energy and mass cannot be created or destroyed during physical changes or chemical reactions."
Explanation: The law of conservation of mass states that the total mass of a closed system remains constant over time. It means that in any physical or chemical changes, the total mass of the substances involved before the change is equal to the total mass after the change. In other words, mass is neither created nor destroyed during these processes.
Similarly, the law of conservation of energy states that energy cannot be created or destroyed; it can only be transferred or transformed from one form to another. The total amount of energy in a closed system is constant. This applies to both physical and chemical processes.
Therefore, the principle behind both laws is that energy and mass are conserved, meaning they cannot be created or destroyed, only transformed or transferred.
