Which is less dense cold air or cold water?
cold air because when the temperature drops hot air rises and cold air comes to ground level,cold water and hot water have the same density.
What is happening when water droplets appear on the outside of a cold glass of water?
The air has moisture (water dissolved in the air). The amount of air that can be carried in the air depends on the temperature. Warmer air can hold more water in it than cold air. When the cold glass is exposed to the air, the air touching the glass gets cold, is no longer able to hold as much water and the water in the air condenses (comes out of solution) on to the outside of the glass.
How does the water on the outside of a cold glass get there?
There is water in the form of water vapor, sort of like steam, in the air. But, the amount of water the air can hold depends on the temperature of the air. The hotter it is the more water it can hold. But, when the air touches the side of a cold drink glass the temperature at that place drops dramatically and the air can't hold nearly as much water as it has been, so the water comes out of the air (condenses) onto the glass.
When energy is transferred from the air to the water what happens to most of the energy?
Most of it will end up in the water It travels through the water.
Why are bubbles formed when chalk is dipped in water?
due to capillary action water raises in chalk.. and the air in it comes out in form of bubbles...
From where do the living things on earth receive most of their energy?
that depends on what it is. if its a plant it comes from air water and sunlight. if its an animal it comes from food water and sleep. if you are only looking for one thing that energy mostly comes from it would be water.
How does oxygen get in to water?
it comes from the air around you
Where does matter from a plant come from?
It comes from soil, water, and air.
Where does most of the evaporation comes from?
If you are referring to water vapor in the atmosphere, most comes from the largest water source on the planet, the oceans.

Which substance expands the most in boiling water when they are sealed in syringes is it air iron or water?
Air expands the most.
Does salt comes from sea water?
yes Not all salt. There are salt mines all over the world where most of our salt comes from.
Which is less dense cold air or cold water?
cold air because when the temperature drops hot air rises and cold air comes to ground level,cold water and hot water have the same density.
What is the most effective means of corrosion?
I think AIR is the most effective mean of corrosion and the most appealing example is the corrosion of iron when it comes in contact with air.
When water drops form on cold glass where does the water comes from?
The water comes from the air. Air as it exists under normal conditions in the atmosphere contains some small fraction of water vapor. When the glass is cold the water molecules strike the glass and cool off, becoming liquid.
Where do the substances come from in respiration?
Glucose comes from sugar in food. Oxygen comes from air we breath in. Water comes from water we drink. Carbon dioxide comes from gas we breath out. Enery comes from glucose absorbed in the small intestine.
Why does your car leak fluid every time you reverse?
most likely it is water coming from the air-conditioner unit. this water comes from the air that is cooled by the air-conditioner. the water is supposed to drain from the car when the car is level. OR, if the liquid is coloured it is from the engines cooling system. this means you have a leak and it is catching somewhere. when you reverse it runs out of the catchment.
