5. By what process do wet clothes dry?
​

Answer 1

Explanation:

1. 1%
2. as ice
3. naturally
4. below 1°and above 40°
5. Evaporation

Answer 2

Answer: 1 ) 2.5%

2) in some parts of the Arctic these freshwater systems can cover up to 80 percent or more of the total land area

3)We can change a solid into a liquid or gas by changing its temperature. This is known as changing its state. Water is a liquid at room temperature, but becomes a solid (called ice) if it is cooled down. The same water turns into a gas (called water vapor) if it is heated up

4) At temperatures below 32°F (0°C), liquid water freezes; 32°F (0°C) is the freezing point of water. At temperatures above 32°F (0°C), pure water ice melts and changes state from a solid to a liquid (water); 32°F (0°C) is the melting point.

5) By a process called evaporation
