Distillation is a widely used method for separating mixtures based on differences in the conditions required to change the phase of components of the mixture. To separate a mixture of liquids, the liquid can be heated to force components, which have different boiling points , into the gas phase .
The spectrum goes as follows:
red, orange, yellow, green, blue, indigo and violet
Red has the lowest frequency.
Since frequency is inversely proportional to the wavelength, therefore, red has the longest wavelength.
Now, consider, the equation:
E = (hc) / lambda
Since the energy is inversely proportional to the wavelength, therefore, red will have the lowest energy.
Based on this, for the mentioned question:
1- Red has longer wavelength
2- Green has greater frequency
3- Green has greater energy
Answer:
Because dipole - dipole force is stronger than london dispersion force
Explanation:
Intermolecular forces determines a wide range of physical properties of matter of which melting point is one of them.
Both london dispersion forces and dipole- dipole forces are vanderwaals force.
But diople - dipole forces exists between polar molecules which are molecules with permanent dipoles.
In london dispersion forces the dipole is temporary
Ex.some can save animals from being extinct ....also dinisours could have killed us...helps save life form or helps figure out new sciences
