The correct answer for the following questions that are presented above are these ones:
(1) b. Pressure. The <span>physical effect can change the boiling point of a substance is the pressure.
(2) </span><span>Evaporation only occurs at the surface of a liquid. TRUE.</span><span>
(3) </span>d. freezing. The change from liquid to solid, or the reverse of melting, is called freezing.
Answer:
Explanation:
Modern Agriculture - The agricultural practices with modern technique like Fertilizers, Innovative hybrid seed, and utilization of machine call modern Agriculture.
Advantages -
Feeding to the population without scarcity of food grains.
Optimum Utilization of land (Crop intensity more then 300%)
Increased production of food grain.
Global Market - even our mangoes available at US and we are getting California apple too.
Due to factories and Machine use this industry is growing to and empowering good employment.
I hope this helps you :)
There must be an intramolecular force. The oxygen atoms are produced as a result of the breakdown of oxygen molecules. Intramolecular force is necessary to stop the oxygen (O2) in the air from changing into the O atom.
Which force causes attraction between O2 molecules?
The result is the London dispersion force, a fleeting attractive attraction, which is created when the electrons in two neighboring atoms occupy positions that temporarily cause the atoms to form dipoles. This interaction is commonly described by the phrase "induced dipole-induced dipole attraction".
What is the difference between intramolecular forces and intermolecular forces which type is stronger?
In general, intramolecular forces are greater than intermolecular forces. Ion-dipole interaction exerts the strongest intermolecular force, followed by hydrogen bonds, dipole-dipole interaction, and London dispersion. Examples. Hydrogen bonding forces, London dispersion forces, and dipole-dipole forces are the three different kinds of intermolecular interactions. The three different kinds of intramolecular forces are metal bonds, ionic bonds, and covalent bonds.

I'm not 100% sure but I think that's right. Hope I helped you in any way.
Answer: 6.3 * 10^15
Explanation:
wavelength = speed of light / frequency
so rewriting the equation gives frequency = speed of light / wavelength
so 3.0 *10^10 / 4.76 * 10^-6 = 6.3 * 10^15
