(b) Why does water boil at a lower temperature up in the mountains than at sea level? To separate alcohol from water by distillation, is it possible if I heat the mixture to 100 degrees C so water reaches its boiling point? Explain. The boiling point of ethanethiol(36...
Why does water boil at a higher temp then NH_3 when they are both dipoles? Why is a packed column used in fractional distillation? Explain why alum crystals are washed free off impurities with ethanol ice water mixture rather than with room temperature deionized water. ...
Because of this anomalous expansion of water at 4 degrees Celsius, springs in the winter season will develop ice on the top layer and keep the water under that layer in liquid form only. Ã’šÃ‚ That is why all the animals remaining in the water below the ice will survive.T...
Will mediate puts in the boiling water to boil 1 minute to bail out spare; Burns the hot two soupspoon cooking oil in the pot, puts in the meat and the vegetables fries the moment; Again adds the little salt, the pepper, changes the fire, puts in mediates with fries.Finally adds the...
☆ Boil water for five minutes and allow it to cool to50Celsius degree;☆ Pour the indicated amount of water into the bottle or jug;☆ Add one leveled scoop powder to each30ml of water;☆ Stir or shake until the powder is completely dissolved;...
water per person per day. Do not forget about the ice deposits, which you can theoretically melt. And the spacesuit is also useful for "extreme survival": on the planet's surface, it can be either -150 or +120 Celsius degrees. But NASA spacesuits must withstand s...
Interesting and simple experiments with everyday items can help children learn science in a fun and educational way. One particularly interesting trick involves dissolving the hard outer shell of an egg by dissolving it in vinegar. This experiment is an
Why does raising the temperature cause a liquid to boil? Why is evaporation useful? Why do liquids sealed in a closed container have a constant evaporation rate? Why is the melting point of water 0 degrees Celsius? Why does NH3(g) dissolve in liquid water? Explain. ...
What is the vapor pressure of water at 100 degree C? Explain. What is the relationship between the vapor pressure of a liquid and its boiling point? (a) Explain the difference between boiling and vapor pressure. (b) Why does water boil at a lower temperature up in the mo...
When water goes from a liquid to a gas (vapor), how much further apart are the molecules? Why does a compound with a high vapor pressure boil at a lower temperature than a compound with a lower vapor pressure? As a liquid is heated, its vapor pressure: a) disappe...
