It has to be below freezing in order for the snow to fall.
Answer: The heat moves through the atmosphere through the process of radiation.
Explanation:
There are three modes of transfer:
1. Conduction: This type of heat transfer happens when there is direct contact between the two object.
2. Radiation: This type of heat transfer happens when there is direct transfer of energy through space.
3. Convection: This type of heat transfer happens when there is a movement of fluid (liquid or gas) in which convection currents are produced due to the movement of hot fluid upwards and cold fluid downwards.
Thus heat moves through the atmosphere through the process of radiation
Much of biological studies are actually chemistry because of chemical changes that occur within organisms. Similarly, large parts of chemistry are governed by physics.
Answer:
B. N, O, F
Explanation:
Elements in same row of periodic table will have same number of orbitals.
In option A C and D elements are of different row due to which they posses different number of orbitals.
But in option B. N, O, F are in second row of periodic table so same orbitals.
