1) You heat water to 100 degrees. It boils.
Explanation: When water is heated to its boiling point, which is 100 degrees Celsius or 212 degrees Fahrenheit at sea level, it changes from its liquid state to a gaseous state. This process is called boiling.

2) You cross an international date line. The time changes.
Explanation: The international date line is an imaginary line that runs through the Pacific Ocean and marks the boundary between different calendar days. When you cross this line, your time changes because you are moving from one time zone to another. Depending on the direction you are traveling, you either gain or lose a day.

3) It rains. The sky is cloudy.
Explanation: Rain occurs when water droplets in the atmosphere become large enough to fall to the ground due to gravity. Clouds are formed when water vapor in the air condenses into tiny droplets or ice crystals, forming visible clusters in the sky. These clusters of water droplets or ice crystals in the air can block sunlight, resulting in a cloudy appearance.

4) Wood doesn't burn. There is no air.
Explanation: Wood requires oxygen, which is present in air, to undergo the chemical process of combustion or burning. When there is no air or lack of oxygen, wood cannot burn because the necessary component for the reaction is absent.

5) There is no rain. Grass doesn't grow.
Explanation: While rain is not the only factor that affects the growth of grass, it plays a crucial role in providing water, which is essential for plants' survival. Without sufficient rainfall, the soil becomes dry and lacks the moisture needed for grass seeds to germinate and grow. Therefore, in the absence of rain, grass growth is hindered or stunted.
