Water is placed at room temperature at 20 degree C
now after some water evaporate at room temperature
so here we can say speed of water molecules will not change as the temperature is same after evaporation
as we know that total kinetic energy is given by
since temperature is same then energy will not change here
now as water evaporate to vapors then we can say that here all molecules are separated more in vapor phase so force of interaction will be less in this phase
And since potential energy depends on the force so potential energy will decrease in this phase

The area of the kite that is inscribed in a square is 40.5 square units.
Given that the side length of the square in which the kite is inscribed is units. The area of a kite is calculated as given below.
Where d1 and d2 are diagonals of the kite that are equivalent to the length of the square. Hence the area can be given as below.
Hence we can conclude that the area of the kite is 40.5 square units.
To know more about the area, follow the link given below.

Energy radiated from the surface of a protostar which is inreturn is replaced by energy released through gravitational contraction.
This keeps a protostar in thermal equilibrium

B. Convection Cells
C. Emanation Cells
D. Radiation
These patterns are called
B. Convection Cells
The equatorial region receives the maximum amount of sunlight as the sun is directly above it. Due to this, the earth experiences a higher temperature, as a result of which the air in this region becomes warm and less dense. It then slowly rises up towards the upper atmosphere, forming a low pressure zone. This air when rises up, slowly cools, and after sometime it falls back. This continuous motion of air mass creates convection cells in the atmosphere.
Thus, the correct answer is option (B).

b. False
Answer: True
Explanation:
A chemical reaction in which the oxidation number of an atom, ion or molecule changes due transfer of electrons between two reactants is known as oxidation-reduction reaction or redox reaction. In Redox reaction, the oxidising agent brings oxidation by gaining electrons and reducing it self.
Example:
Zn + Cu²⁺ → Zn²⁺ + Cu
Here, Cu²⁺ is an oxidizing agent which got reduced to Cu .
Thus, the given statement is true.
It's true that in an oxidation-reduction reaction, the oxidizing agent always undergoes reduction. The oxidizing agent is a substance that is capable of oxidizing other substances, meaning it causes them to lose electrons. By taking these electrons, the oxidizing agent itself is reduced.
In an oxidation-reduction reaction, also known as a redox reaction, the statement that the oxidizing agent always undergoes reduction is indeed true. The oxidizing agent is a substance that has the ability to oxidize other substances, meaning it causes them to lose electrons. In taking these electrons, the oxidizing agent itself is reduced. This is due to the principle that in a redox reaction, when one substance is oxidized (loses electrons), another substance must be reduced (gain electrons).
