Question

A cook notices a teakettle of water on a stove. There is a cold window close to the spout of the kettle. The water begins to boil and water droplets begin to form on the window.

A. Describe in detail what is happening to the water inside the kettle.

B. Why do water droplets form on the window? Be sure to explain in detail.

(btw this is not social studies, this is science)

Answer 1

A. Inside the kettle, the water is being heated by the stove. As the heat energy is transferred to the water molecules, they gain kinetic energy, causing them to move faster. As the temperature of the water increases, the water molecules start colliding more frequently and with greater force. These collisions increase the overall energy of the water and eventually reach the boiling point.

Once the water reaches its boiling point, it undergoes a phase change from liquid to gas. The rapid movement of the water molecules causes bubbles of water vapor to form and rise to the surface of the water. These bubbles then burst, releasing the water vapor into the air above the kettle.

B. The water droplets form on the window because of condensation. When the water vapor rises from the kettle and encounters the cold surface of the window, it loses heat energy to the window, causing it to cool down. As a result, the water vapor molecules slow down and lose energy, transitioning from a gas state to a liquid state. This process is known as condensation.

Explanation:The window surface provides a cool area for the water vapor to condense and form tiny water droplets. The water droplets collect on the window because the surface of the window is cooler than the surrounding air. This phenomenon is similar to when moisture collects on a cold glass of water on a hot day.

The presence of the cold window close to the spout of the kettle provides an ideal surface for the water vapor to condense, leading to the formation of water droplets on the window.

Answer 2

Step-by-step explanation:

simple answer:
A. it means the water is getting hotter/ the temperature is increasing because we are boiling the water.

B. since its getting hotter and it tends to create steam. The steam is formed of droplets and oxygen which is why when it hits the door it creates small water droplets.

expanded detail answer:

A. When the cook puts the teakettle of water on the stove, the heat from the stove transfers to the kettle. As the temperature of the water inside the kettle increases, the water molecules gain energy and begin to move faster. This increased movement of water molecules is what causes the water to boil. Boiling is the process in which the water changes from its liquid state to its gaseous state, known as steam. So, what is happening inside the kettle is that the water is reaching its boiling point and transitioning into steam.

B. The formation of water droplets on the window occurs due to a phenomenon called condensation. When the steam from the kettle comes into contact with the cold window, it loses heat energy to the window, causing the steam to cool down. As the steam cools down, it undergoes a phase change from a gas (steam) to a liquid (water). This phase change is known as condensation. The water vapor in the steam condenses into tiny droplets of liquid water on the window surface. These droplets are what we observe as water droplets forming on the window.

In summary, the water inside the kettle is boiling due to the heat from the stove, and the formation of water droplets on the window is the result of condensation when the hot steam comes into contact with the cold window surface.
