Heat will flow from the water to the iron block until both are at the temperature of the container.
Heat will flow from the water to the iron block until both are at the temperature of the container.

Heat will flow from the iron block to the water until both are 50 degrees Celcius.
Heat will flow from the iron block to the water until both are 50 degrees Celcius.

Heat will flow from the iron block to the water until both are 250 degrees Celcius.
Heat will flow from the iron block to the water until both are 250 degrees Celcius.

Heat will flow from the iron block to the block to the water until both reach a temperature somewhere between 50 degrees Celcius and 25 degrees Celcius.
Heat will flow from the iron block to the block to the water until both reach a temperature somewhere between 50 degrees Celcius and 25 degrees Celcius.

Answer 1

The correct statement that best describes what will be observed in this experiment is:

Heat will flow from the iron block to the water until both reach a temperature somewhere between 50 degrees Celsius and 250 degrees Celsius.

In this scenario, since the iron block is at a higher temperature than the water, heat will flow from the iron block to the water until thermal equilibrium is reached. The final temperature will be somewhere between the initial temperatures of the two objects.

Answer 2

A student drops substance A into substance B. What will happen?(1 point)
Responses

Substance A will become warmer as heat flows from substance A to substance B.
Substance A will become warmer as heat flows from substance A to substance B.

Both substances will reach 50°C due to heat exchange.
Both substances will reach 50°C due to heat exchange.

After some time passes, the substances will reach the same temperature.
After some time passes, the substances will reach the same temperature.

Both substances will reach 25°C due to heat exchange.

Answer 3

The correct response is:

After some time passes, the substances will reach the same temperature.

In this scenario, when two substances at different temperatures are mixed, heat will flow from the hotter substance to the cooler one until thermal equilibrium is reached, meaning they will eventually come to the same temperature. The specific final temperature will depend on the initial temperatures and the heat capacities of the substances, but they will equalize rather than necessarily reaching a specific temperature like 25°C or 50°C.

Answer 4

When you add cold milk and hot chocolate, they will slowly blend as the cooler liquid mixes with the warmer liquid. Eventually, the heat will be spread out evenly through the entire liquid. Which statement best explains why this happens?(1 point)
Responses

The liquids attract each other because the densities of the liquids are the same.
The liquids attract each other because the densities of the liquids are the same.

Heat always moves from areas of higher temperature to areas of lower temperature.
Heat always moves from areas of higher temperature to areas of lower temperature.

Cold liquids rise and hot liquids sink making the liquids mix.
Cold liquids rise and hot liquids sink making the liquids mix.

The molecules of the two liquids form chemical bonds to spread energy.

Answer 5

The correct statement that best explains why this happens is:

Heat always moves from areas of higher temperature to areas of lower temperature.

This principle of heat transfer explains that the thermal energy from the hot chocolate will flow into the cold milk, causing the two liquids to blend and eventually reach an equilibrium temperature as they mix.
