Why does a puddle dry up after it rains?
because the water gets evaporated by the sun
What is the reason behind fog?
Actually, fog is a cloud of condensed water vapour present in the air. In cold days, water vapours become more cool to condensed by extracting its energy to its near by nitrogen vapours present in air (as boiling temperature of nitrogen is very low approx. -200C). Thus the condensed water vapour suspend in the air to make a cloud i.e. fog. O.P.Yadav GCET, Gr Noida
Is water negatively charged or positively charged?
Water is neutral. This is because it has hydrogen and oxygen particles. One is positively charged, one negatively. This means that they cancel out - water is neutral.
why does vapours form on a mirror?
because the h2o in the air contracts on contact with the cold mirror causing it to change into a denser state of matter which in this case is liquid.
Is water positively charged or negatively charged?
Water is neutrally charged. It has H+ and OH- ions. 1 positive and 1 negative charged ion. The positive and negative ions cancel each other out and therefore we end up with a neutrally charged water atom.
What are vapours?
water vapours are particles of water when water is boiled at a certain temperature the smoke you get is water vapours
What is the difference between water and water vapours?
water is a liquid but water vapours is steam... when we boil water it will turn into steam which is called water vapours...
How humidity and relative humidity different?
Humidity means amount of water vapour present in air with respect to total amount of air. Relative humidity means ratio of amount of water vapours per unit volume of air to the capacity of air to held maximum water vapours in unit volume of air, at given air temperature.
How does increased air movement effect evaporation?
It carrys away the vapours so more water will evaporate
How can you justify that air is a homogenous mixture. Identigy substances present in it?
Air is a mixture of nitrogen oxygen co2 noble gases and water vapours
What increase the rate of transpiration in a plant?
The rate of transpiration depends on some environmental factors such asTemperature and windWhen the temperature is high rate of evaporation increases as warm air can hold more water vapours than the cold air. Windy condition also increase the rate of transpiration as wind remove water vapours from around the leaf. HumidityWhen there is more humidity in air, transpiration would be considerably low as the air is already saturated with water vapours and it will be unable to absorb more water so little water will diffuse out of the leaves. LightLight greatly influences the opening and closing of stomata. During day light the stomata remain open and allow water vapours from the leaves to diffuse into the atmosphere. Atmospheric pressureReduction in the atmospheric pressure enhances the rate of transpiration.

What are clouds made of and how high are they off the ground?
Clouds are made of water that has dried up and become water vapours. These vapours rise into the air and cool down into clouds. When the clouds are completely cooled, it will rain. Clouds can be at a varying height, depending on the vapour density.

What do you call it when water vapor turns into water?
condensation of vapours
Why happens during condensation?
Hot air with water vapours hit a old surface causing water droplets to form. If the hot air reaches a cold atmosphere, it's called precipitation aka rain.
What is the yield of combustion of ether in air?
Ethers are the compounds of Carbon , Hydrogen and Oxygen so on combustion they produce Carbon dioxide and water vapours.
