How much energy is absorbed when 23.1 moles of water vaporize?
540 calories per gram is absorbed when water vaporizes at its boiling point. Called the latent heat of vaporization. 540 x 23.1 x 18 = 224532 calories
What Stokes shift indicate?
When a crystal absorbs a photon, that energy becomes part of the crystal. When that same crystal releases a photon, that photon is taking energy away from the crystal. The Stokes Shift is a measure of the difference in wavelength (and thus energy) of photons absorbed by a crystal and then immediately re-emitted by that same crystal. The energy shift between the two photons is an indication of how much energy has been permanently absorbed by the crystal in the form of heat.
When an electron falls back to its ground state how much energy is released?
It releases the same amount of energy that it absorbed when it was excited to a higher energy state.
How much energy does it take to melt ice?
Heat because Ice and water would thaw out and begin to heat up
What is the ability of a substance to absorb heat energy is called?
Specific heat capacity describes how much heat energy that is needed to raise the temperature of material.
Does radiant energy produce heat energy when it strikes matter?
To the extent to which the energy is absorbed, yes. Reflectivity and color determine how much energy is absorbed, but no matter can reflect 100% of the energy striking it. Some will be absorbed by the molecules.
How much heat exactly is absorbed by the ozone or what temperature would the earth be if there was no ozone?
23 percent of incoming solar energy is usually absorbed by the ozone. Temperature, not how much
How much heat energy does the sun give out?
That depends what exactly you classify as "heat energy". However, basically all of the the energy emitted by the Sun - including visible light, which contains a large portion of the Sun's energy - can be converted to heat when it is absorbed.
What factor determines how much heat can be absorbed by the brakes drum?
Too much heat would result in brake damage, which is absorbed in the brake drum.
A pulse sent down a long string eventually dies away and disappears what happened to its energy?
It is converted into heat in the string and the environment.
How much heat is absorbed by land and sea?
51%
Is radiant energy an alternative use of energy?
Energy can be transferred by EM radiation. Heat is transferred by infra red because these frequencies are absorbed on the surface of bodies. Microwaves are EM of much higher frequency which penetrate soft tissues and stimulate water molecules to produce heat.
How much energy is absorbed when 356 g of ethanol 46.0 gmol boils?
The heat of vaporization of ethanol is 38.6 kJ/mol-298 - 299 KJ
How much energy is absorbed when 356 g of ethanol 46.0 g molboils The heat of vaporization of ethanol is 38.6 kJ mol?
298-299 kJ
A pulse sent down a long string eventually dies away and disappears.What happens to its energy?
The energy is dissipated. That means it is absorbed, and somehow converted to other forms of energy. Typically, much of this dissipated energy gets converted into heat.
How much heat does it take to melt iron?
iron melts at 1536 °C
When 30 grams of water is converted into steam how much heat is absorbed?
q = mHvq = heatm = mass (30g)Hv = heat of vaporization (2,260J/g)q = (30g)(2,260J/g)q = 67,800JWhen 30 grams of water is converted into steam, how much heat is absorbed?67,800J of heat, also represented as 67.8kJ of heat is absorbed.
