Answer:
Viscosity of water decreases markedly with increasing temperature. When the viscosity decreases, the flow resistance decreases. So for the same driving force, that is the pressure drop per unit length, the water flow rate will be higher.
Hope this helps :)
The energy of an electron can be change only by set amounts.
The electrons in an energy level of an atom can only move to a higher or lower energy level only if it absorbs or emits a certain amount of energy. If the electron does not have enough energy to move to the next energy level then it will never move.
Atomic number = 15
Name = Phosphorous
Atomic symbol = P
Group number = V(A)15
P = Non -metal
How to find all valves of Z=15?
Here, we are going to find out the name, symbol and group numbers element with the following Z value and their classification as a metal, metalloid, or nonmetal.
The atomic number of the element is 15
Therefore, the name of the element is Phosphorous
The atomic symbol of the element is P
The group number of is V(A)15
P is a Non- metal
Hence, the element is Phosphorous

Answer:
Mn is the oxidizing agent.
N is the reducing agent.
Explanation:
Hello!
In this case, according to the undergoing chemical reaction, it is seen that the manganese in KMnO4 has an oxidation state of 7+, in MnSO4 of 2+ and nitrogen in KNO2 is 3+ and in KNO3 is 5+; thus we have the following half-reactions:
Thus, since manganese is undergoing a decrease in the oxidation state, we infer it is the oxidizing agent whereas nitrogen, undergoing an increase in the oxidation state is the reducing agent.
Best regards!
Because gravity is trying to pull it down not up and when it's going down it's going with gravity not against it.
