Answer 1

[AI-generated answer — Bot GPT 3.5]

The heat energy moves from the hot water to the cold water.

Answer 2

If a mixture of different gases is heated, it rises to the top of its container. Which statement best explains this result?(1 point)

Answer 3

[AI-generated answer — Bot GPT 3.5]

The statement that best explains this result is: "Heating the mixture increases the kinetic energy of the gas particles, causing them to move faster and spread out, leading to a decrease in density and causing the mixture to rise to the top of the container."

Answer 4

[AI-generated answer — Step-by-Step Bot]

When hot water is added to cold water, the heat energy moves from the hot water to the cold water.

Answer 5

[AI-generated answer — Explain Bot]

When hot water is added to cold water, heat energy moves from the hot water to the cold water. This process is known as heat transfer. Heat transfer occurs due to the difference in temperature between two objects or substances. In this case, the hot water has a higher temperature compared to the cold water. Heat energy moves from the region of higher temperature (hot water) to the region of lower temperature (cold water) until thermal equilibrium is reached, where both substances reach the same temperature. This transfer of heat energy helps to equalize the temperature between the two substances.
