Question

1. what are the three states that water can exist in? 2) what is the scientific term for the water cycle? false when water vapor turns into a liquid this is called condensation. 4) what is the scientific term for rain? 5) what is used to make invisible ink in the uffty trick? how is invisible ink connected to the water cycle? 6) true false all molecules are always going at the same speed. 7) true false in nature water is recycled. 8) why does a persons glasses fog up when the temperature changes? 9) true false clouds form when air cools.

Explanation:

1. Water can exist in solid (ice), liquid (water), and gas (water - vapor) states based on temperature and pressure changes.
2. The scientific term for the Water Cycle is the hydrologic cycle, which describes the continuous movement of water on, above, and below the surface of the Earth.
3. When water vapor turns into a liquid, it is called condensation, so the statement is true.
4. The scientific term for rain is precipitation, which also includes other forms like snow, sleet, and hail.
5. Lemon juice can be used to make invisible ink. In terms of connection to the water - cycle, the water in lemon juice evaporates (similar to evaporation in the water - cycle), leaving behind a chemical residue that can be revealed with heat.
6. Molecules move at different speeds depending on temperature and other factors, so the statement "All molecules are always moving at the same speed" is false.
7. In nature, water is recycled through the water - cycle, so the statement "In nature water is not recycled" is false.
8. A person's glasses fog up when the temperature of the glasses is lower than the dew - point temperature of the surrounding air, causing water vapor in the air to condense on the glasses.
9. Clouds form when air rises, cools, and water vapor condenses around tiny particles. This is related to the condensation and evaporation processes in the water - cycle.

Answer:

1. Solid (ice), liquid (water), gas (water - vapor)
2. Hydrologic cycle
3. True
4. Precipitation
5. Lemon juice; water in lemon juice evaporates similar to evaporation in the water - cycle
6. False
7. False
8. The temperature of the glasses is lower than the dew - point temperature of the surrounding air, causing water vapor to condense on the glasses
9. Clouds form when air rises, cools, and water vapor condenses around tiny particles, related to water - cycle processes
