Why do the tunnels not need to be moved to water the plants?
The tunnels do not need to be moved to water the plants because they are designed to allow water to flow through them effectively. This setup enables the moisture to reach the plant roots without disrupting their growth. Additionally, the tunnels can help retain humidity and reduce evaporation, making the watering process more efficient. Ultimately, the design maximizes water usage while minimizing the need for physical adjustments.
Does polythene dissolve in water?
No, polythene does not dissolve in water as it is a non-polar polymer and water is a polar solvent. This lack of attraction between the polythene molecules and water molecules prevents it from dissolving.
What happens when a polythene strip is rubbed on a woolen cloth and then placed near a thin stream of running water from a tap?
The polythene becomes negatively charged.
Does polythene absorb water?
No - it is a synthetic polymer and it is not a natural polymer like cotton which has excellent absorption qualities.
What does polythene feel like?
Polythene feels smooth and slightly waxy to the touch. It is a durable and flexible material commonly used in packaging and construction due to its strength and water-resistant properties.

Does polythene float or sink?
Polythene, also known as polyethylene, typically floats on water because it has a lower density than water. This is due to its molecular structure, which enables polythene to be less dense and float on the surface of water.
Does polythene dissolve?
No, at least not in water.
What are the effects of polythene pollution?
One of the effects of the polythene pollution is that it interacts with water to form hazardous chemicals. It leads to the death of animals which consume the polythene which has not been disposed properly.
What are the Elements produced by polythene burning?
When polythene burns, it produces carbon dioxide, water vapor, and trace amounts of carbon monoxide and volatile organic compounds. Burning polythene releases harmful chemicals into the environment and should be avoided.
What can you do as a group to stop water pollution?
to stop using polythene's

Who is the greek god of tunnels and water?
There is no greek god of tunnels but Hades was the god of the underworld while Posiedon was the god of the sea (AKA water).
What are the Slogans on hazards of polythene?
Polythene is not biodegradable * Polythene threatens the life in the water bodies. The polythene articles (e.g. six pack rings) affects the survival of animals the aquatic and marine ecosystems. * Polythene is also likely to clog the drains causing problems in the water flow of the pipes. The pipe blockages would cause flooding and the free flow of water is disturbed. * Polethene is harmful for animals if swallowed. It can accumulate in the bowels which ultimately becomes lethal to the animal. * In most households poly bags are used to preserve food items. Reused bag may be contaminated by materials harmful to human health.
What is water pressure tunnel?
Pressure tunnels are tunnels used to divert water from a reservoir, usually to a hydroeletric power house. They take their name due to the fact that, instead of most commons tunnels in wich the main load is geostatic (pointing inwards the tunnel), pressure tunnels are submited to high water pressures pointing outwards the tunnel.
