Explanation
To perform filtration, you need water with activated carbon to remove impurities, a funnel to hold the filtration paper, a tripod to support the funnel, and filtration paper to separate the solid particles from the liquid. The activated carbon helps in adsorbing and removing contaminants from the water, while the funnel and filtration paper facilitate the separation process. The tripod provides stability to the setup during filtration.

Explanation
Neutral water has a pH of 7 because it is neither acidic nor alkaline. A pH of 7 indicates a neutral solution, meaning that the concentration of hydrogen ions (H+) is equal to the concentration of hydroxide ions (OH-) in the water. This balance between acidity and alkalinity makes water neither acidic nor alkaline, resulting in a pH of 7.

Explanation
There are three forms of water: solid (ice), liquid (water), and gas (water vapor).

Explanation
Steam is the gaseous form of water. When water is heated to its boiling point, it undergoes a phase change and transforms into steam. Steam is invisible and consists of water vapor, which is composed of tiny water droplets suspended in the air. It is commonly observed when boiling water or when hot water comes into contact with cooler air. Thus, the correct answer is gas.

Explanation
Water boils at 100 degrees Celsius. This is the temperature at which the liquid water turns into water vapor or steam. At this temperature, the water molecules have enough energy to overcome the forces holding them together and transition into a gaseous state. Therefore, to boil water, it needs to reach a temperature of 100 degrees Celsius.

Explanation
Water with activated carbon, a funnel, tripod, and filtration paper are needed for filtration. Filtration is a process used to separate solids from liquids or gases by passing the mixture through a medium that retains the solid particles while allowing the liquid or gas to pass through. Water with activated carbon is commonly used in filtration to remove impurities and contaminants. The funnel and filtration paper are used to hold the mixture and allow the liquid to pass through while trapping the solid particles. The tripod provides support for the funnel during the filtration process.

Explanation
There are three forms of water: solid (ice), liquid (water), and gas (water vapor).

Explanation
Water boils at 100 degrees Celsius. This is the temperature at which water changes from a liquid to a gas, creating bubbles and steam. At lower temperatures, water is in its liquid state, and at higher temperatures, it turns into steam. Therefore, to boil water, it needs to reach a temperature of 100 degrees Celsius.
