What else can I help you with?
When trees transpire releasing gaseous water into the atmosphere they can absorb heat from their environment and cool it down What property of water is responsible for this activity?
The high specific heat capacity of water is responsible for trees absorbing heat from their environment to cool it down when they transpire. Water's ability to absorb and release large amounts of heat helps regulate temperatures in the surrounding area.
What is a characteristic of water A dissolves ionic substances B high density C Solid form more dense than liquid D high heat of vaporation?
The answer is C. Ice is less dense than water and thus floats.
Example of heat of vaporation?
The heat of vaporization is the energy required to change a substance from liquid to gas at its boiling point without changing its temperature. For example, the heat of vaporization for water is 2260 J/g at its boiling point of 100°C. This means that 2260 Joules of energy are needed to vaporize 1 gram of liquid water at 100°C.
word for slow vaporation?
Slow
What are the 2 types of vaporation?
When liquid water turns into a gas or vapor, the process is evaporation. When solid water (ice) turns into a gas or vapor, the process is sublimation.
Is vaporation a endothermic change?
Vaporization is an endothermic change.
When water is heated it changes from a solid to a what?
That one is easy. It becomes a gas. That process is called "Vaporation". The steam that comes out of the water is the gas. It only becomes a gas when the water boils.
Explain why the water is boiling at the top of the tube but the ice at the bottom hasn't melted?
If heated at the top only, all heat is absorbed by boiling (vaporation) and warm water is lifted up by its lower density than the more dense cold water stays under, downwards. This colder water does not conduct the 'top' heat very well and also the glass tube is a good insulator. So it takes a long time to heat up the bottom.
Does energy increase or decrease in vaporation?
Energy increases in vaporization
What are the 5 changes of state?
sublimation melting freezing condensation vaporation
What is the opposite of vaporation?
the opposit of vaporation isso thats thats what you get on your answer sheet if you dont know how to do homework. Next time pay attanion to your teacher in class.Bet you cant woop me though and your dum because this is the wrong answer!
What is the heat of vaporation for beryllium?
Beryllium melting point: 1 278 0C. Beryllium boiling point: 2 469 0C.
