During the phase transition vapour --> liquid water, the temperature of the water does not change; the molecules of water release heat and the amounf of heat released is equal to
where
m is the mass of the water
is the latent heat of evaporation.
For water, the latent heat of evaporation is
, while the mass of the water is
so, the amount of heat released in the process is
Answer:
Atoms in a element on the periodic table I dont know which one tho so try google that sorry I am not much of a help
Explanation:
Answer:
500 watts
Explanation:
Recall that the definition of power is the amount of energy delivered per unit of time.
In our case, the energy delivered is potential energy which we can estimate as the product of the weight of the object times the distance it is lifted above ground:
200 N x 10 m = 2000 Nm
then the power is the quotient of this potential energy divided the time it took to lift the object to that position:
Power = 2000 / 4 Nm/s = 500 Nm/s = 500 watts
Answer:
reflection
Explanation:
an example would be looking in the mirror
The answer should be B, Condense.
Freezing is when a liquid transforms into a solid.
Sublimation is when a solid goes straight to a gas.
Evaporation is when a liquid transforms into a gas.
