Study the scenario.
A match is lit in an isolated system. The match releases 40 J of heat energy. Which choice correctly describes what happens to the total energy of the system over time?
The total energy of the isolated system eventually becomes zero once the match goes out.
The total energy of the isolated system decreases because the heat from the match dissipates into the air.
The total energy of the system remains at a constant 40 J of energy because energy is conserved in an isolated system.
The total energy of the isolated system increases because the heat warms up the surrounding air.
Constant 40J. No energy or mass can be transferred in an isolated system.
Thank you!
Well, isn't this a hot topic! When a match is lit in an isolated system and releases 40 J of heat energy, the total energy of the system doesn't just disappear like a magician's trick gone wrong. It actually decreases because that heat from the match escapes into the air like a sneaky little ninja. So, the correct option is: "The total energy of the isolated system decreases because the heat from the match dissipates into the air." It's not quite like a disappearing act, but it's certainly a disappearing act for the energy! Just don't get too fired up about it, okay?
The correct choice is: The total energy of the isolated system remains at a constant 40 J of energy because energy is conserved in an isolated system.
To determine what happens to the total energy of the system over time, we need to understand the concept of energy conservation.
In an isolated system, energy is conserved, meaning it cannot be created or destroyed, only transferred or transformed from one form to another.
In this scenario, the match releases 40 J of heat energy. Since the system is isolated, the total energy of the system will remain constant. The heat energy released by the match will disperse and spread out into the surrounding air, but it will still contribute to the total energy of the system.
Therefore, the correct choice is: The total energy of the system remains at a constant 40 J of energy because energy is conserved in an isolated system.
