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.
Scientists believe plant life moved from water to land and that plants evolved from multicellular?
green algea
Polythene can burn in oxygen to make carbon dioxide and water what is the formula?
polythene is a polymer of ethene. polythene primary while synthesis is a waxy solid, but it is made into transparent form by processing. The waxy solid which is the pure polythene burns in oxygen at elevated temperature to give carbon dioxide and water. but the processed polythene which we use in our daily lives, will burn in air to form CO2 and H2O along with other substances say carbon particles viz SPMs'. the equation is such that: - (C2H4)n + 3nO2 ----> 2nO2 + 2nH2O I am doing research on extraction of fuel from polythene, so I know a little on combustion products of polythene you. yours faithfully, Piyush Nanda.

How did plants move from water to land?
Plants moved onto land after algae was entrapped in evaporating ponds, and cast up to the sea shore, and as a majority died, a few survived to be the plants we see on land today.
Does polythene absorb water?
No - it is a synthetic polymer and it is not a natural polymer like cotton which has excellent absorption qualities.
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 can you do as a group to stop water pollution?
to stop using polythene's
What are the Elements produced by polythene burning?

Who is the greek god of tunnels and 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.

How does water move underground?
Water moves underground through pipes and man made tunnels. If there are no pipes or tunnels, water finds little holes or crevices to move through.
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.

How did mespotamians get water to their?
They used irrigation tunnels so when it rained or flooded the water would be caught and flow to the crops they also connected these tunnels to rivers near by
