Question

investigate

1. use the menu on the right - side of the program to select water and solid. draw and describe what you see in the space below.
2. notice the thermometer at the top of the program. change from celsius to kelvin. what temperature is showing in this thermometer?
3. now use the slider on the bottom of the program to add heat. what happens to the water as you increase the temperature?
4. now use the slider on the bottom of the program to remove heat. what happens to the water as you decrease the temperature?

Explanation:

Step1: Identify the diagram

The diagram shows the molecular structure of water in solid - ice form. The water molecules are arranged in a regular, ordered pattern.

Step2: Temperature conversion

To convert Celsius to Kelvin, we use the formula $K = ^{\circ}C+ 273.15$. But since the Celsius temperature is not given, we can't calculate the Kelvin temperature precisely. However, if we assume a standard freezing - point of water in Celsius ($0^{\circ}C$), then in Kelvin it is $0 + 273.15=273.15\ K$.

Step3: Adding heat

As you increase the temperature by adding heat to ice (solid water), the ice will start to melt. The ordered arrangement of water molecules in the solid state will start to break down as the intermolecular forces are overcome by the added thermal energy, and the ice will transition to the liquid state.

Step4: Removing heat

As you decrease the temperature by removing heat from water (in any state), if it is in the liquid state, it will start to cool down. If the temperature is decreased further to the freezing - point ($0^{\circ}C$ or $273.15\ K$), the water will start to freeze and transition back to the solid state, with the water molecules arranging themselves in an ordered pattern again.

Answer:

1. Without the Celsius value, we can't give an exact answer. But if at freezing - point of water ($0^{\circ}C$), it is $273.15\ K$.
2. The ice melts and turns into liquid water.
3. If in liquid state, it cools down. If at freezing - point, it freezes into ice.
