The kinetic energy of a photon can be calculated from the product of the planck's constant and the frequency of the light. In this problem, we are given the wavelength. Frequency and wavelength are related. We do as follows:
E = hv where h is the Plank's constant and v is the frequency (v = speed of light / wavelength )
E = h (speed of light / wavelength)
E = <span>6.63x10^-34 ( 3x10^8 )/ (1.50x10^-7 )
E = 1.326x10^-18 J = 8.26 eV</span>
Answer: Dew point temperature is the temperature that a parcel of air would have to be cooled to reach saturation.
Explanation:
Dew point is the temperature in which a parcel of air would be cooled in order to become saturated with water vapour. When the air cool further, the water vapour condense to form dew or liquid water. When air cools to it dew point when its have contact with a colder surface, water will condense on its surface.
An instrument with high amplitude has loud sound. An instrument with low amplitude has soft sound.
Answer:
For thermodynamics the fugacity (fi) of a non ideal gas is defined as the product between the activity (ai) of the gas and 1 bar of pressure.
Explanation:
For thermodynamics the fugacity (fi) of a non ideal gas is defined as the product between the activity (ai) of the gas and 1 bar of pressure.
Also, in a gas mixture the fugacity (fi) of every component of the mixture is define by a coefficient of fugacity (Фi) multiplied by the partial pressure of the gas (Pi) :
Ф
The coefficient of fugacity (Фi) is a measure of the deviation from the ideality of the gas. Thus, for an ideal gas Фi = 1 and the fugacity (fi) turns equal to partial pressure:
If Фi = 1 ⇒
