Answers
Answer:1) person 2) person
Explanation:
I just did the assignment
The correct answer is the computer's thermal energy will be transferred to the human.
Why does energy flow from the computer to the person?Computers are often devices that transform electrical energy into thermal energy, which is then supplied to the user. The energy is transferred from the higher to the lower amount. In this example, the computer produces more thermal energy than the person, which is why energy flows from the computer to the person.Learn more about computer thermal energy here:-

Water evaporating in an open system, water freezing, cookie dough baked into a cookie, and sugar dissolving into water are all examples of statements that demonstrate the law of conservation of matter.
What is law of conservation?A conservation law in physics asserts that a specific observable property of an isolated physical system doesn't change over time.A physical property, or measurable amount, does not change over time in an isolated physical system, according to the conservation law, often known as the law of conservation, which is a principle in physics.According to the principle of mass conservation, neither chemical processes nor physical changes can create or destroy mass in an isolated system. The mass of the products and reactants of a chemical reaction must be equal, in accordance with the law of conservation of mass.To learn more about law of conservation refer to:
