What is the electrical method to determine the specific latent heat of vaporisation?
coclude the specific latent heat of vaporization
What is the latent of vaporization?
The latent heat of vaporization is what is commonly referred to as boiling. This is the amount of energy require to change from a state of liquid to vapor.
What is the purpose of the water trap in determining the latent heat of vaporization of water?
to prevent water from entering the calorimeter and allow only the gas.
What does the heat latent heat of vaporization measure?
The energy required to boil a substance
Perspiration cools the body because?
the water is using heat to undergo a phase change , the water's latent heat of vaporization is being pulled from your body
What step changes liquid water to water vapor?
Vaporization is the change of liquid water to water vapor. Vaporization requires addition of the latent heat of vaporization to liquid water. The latent heat of vaporization supplies the liquid water molecules with enough energy to become vapor molecules. The latent heat of vaporization at 1.0 atmosphere pressure is about 1000 Btu per lbm ( 2260 kJ per kg ).
The amount of energy needed to change a material from a solid to a liquid is the heat of what?
The latent heat of evaporation
How your body cooled when you perspire?
Perspiration coats the outside of the skin with moisture (water). The water evaporates. Evaporation requires heat to be absorbed by the water (the latent heat of vaporization). Heat is removed from the body surface to provide the water with the latent heat of vaporization.
What is the electrical method to determine the specific latent heat of vaporisation?
coclude the specific latent heat of vaporization
What is the latent of vaporization?
The latent heat of vaporization is what is commonly referred to as boiling. This is the amount of energy require to change from a state of liquid to vapor.
What is the purpose of the water trap in determining the latent heat of vaporization of water?
to prevent water from entering the calorimeter and allow only the gas.
Are swamp coolers effective?
the water's latent heat of vaporization is being pulled from the air, the water pulls heat from the room to undergo a phase change.
What is the heat of vaporization value of water?
It is approximately 539.4 calories per gram.
What does the heat latent heat of vaporization measure?
The energy required to boil a substance
Silicon has a relatively large latent heat of vaporization of 12800 Jg. This indicates that silicon has?
The boiling point has a high value.
What is the Latent heat of vaporization for ethyl acetate?
87.6kcal/kg
How your body is cooled when you perspired?
When your body perspires, it is coating your body with sweat. When it is really hot out, the sweat evaporates, cooling your body by removing the sweat.
