Question

luka is heating up a pot of water on a gas stove. which of the following best describes the energy in this system? (1 point) this is an isolated system, so matter and energy are exchanged with the surroundings. this is a closed system, so no matter or energy is exchanged with the surroundings. this is an open system, so matter and energy are exchanged with the surroundings. this is a water system, so no matter or energy is exchanged with the surroundings.

Explanation:

1. Analyze each option:

• Isolated system: Does not exchange matter or energy with surroundings. The first option's description is wrong for isolated system.
• Closed system: Exchanges energy but not matter with surroundings. The second option's description is wrong for closed system.
• Open system: Exchanges both matter and energy with surroundings. When heating water on a gas stove, water can evaporate (matter exchange) and heat is transferred (energy exchange), so it's an open system. The third option's description matches.
• "Water system" is not a standard thermodynamic system category, and the description is incorrect as matter and energy do exchange.

Answer:

C. This is an open system, so matter and energy are exchanged with the surroundings.
