Why the ethanol heated in a water bath instead of being heated directly?
Because it is inflammable
Why will there be air bubbles forming when water is being heated?
As the flask expands,hor air is being pushed out,therefore,air bubbles are formed.
How do bubbles form in boiling water?
When water boils, the heat converts some of the water to steam and each bubble is a steam bubble. Steam is a gas that is lighter than water, and so the bubbles rise to the surface of the water where the steam is released. As the steam cools in the air, it forms water vapor, and that is what we see. Most people call the vapor "steam", but steam is a transparent gas, like air.
What is the solvent in soap solution?
When soap is added to water, water is the solvent
Is food being heated in the oven a conversion from chemical energy to mechanical?
yes it is
Why the ethanol heated in a water bath instead of being heated directly?
Because it is inflammable
Is hot water an chemical or physical change?
That is a physical change because it has not had an explosive or bubbly substance.
Why does water lose the most heat when its just stopped being heated?
water loses it's most heat because the stored in the water gets out in steam.
Why is an expansion device needed for water heater?
because the steam that the water makes when it is being heated needs to go some where, if it deos not expand then it will explode.
Why does food sizzle when being cooked?
Water being heated, and turning to steam.
What are 4 convections?
the air being heated from a fireplace,air from a furnace,boiling water,the air being heated in a hot air balloon.
Is water being heated up a chemical change?
yes
Where does the water go after being heated in a nuclear reactor?
Nuclear reactor heats water making steamTurbines are turned by steamCooling tower condenses spent steam back to waterwater is returned to the nuclear reactorIts actually a bit more complicated than this single closed loop, because the water heated by the nuclear reactor itself becomes slightly radioactive. Because of this radioactivity, for safety reasons a system with two closed loops connected by a heat exchanger is used. In the primary loop the water just keeps circulating between the nuclear reactor and the heat exchanger. In the secondary loop the water circulates as in the steps listed above, but substitute Heat exchanger for Nuclear reactor.
What does the conversation of water mean?
I assume it is "what does the conversion of water mean?" Water can be converted to ice by being frozen. Or to steam to drive a steam engine by being super heated. Or changed to water vapour by being heated until the water is evaporated away (as in desalination of sea water) and the water vapour to be condensed back into drinkable water free of salt.
Can water being re heated and turning into water vapour be reversed?
Yes, it's called condensation.
How does the sunlight warm the land air and water?
Land and sea are heated by absorbing radiant energy from the sun. Air is heated indirectly by being in contact (conduction) with land or water.
How does water changefrom one state to another?
Water changes from one state to another by being heated or cooled
