The maximum number of electrons that an energy level can hold is determined from the formula 2n^2 equals the total number, where n is the energy level. The first energy level holds 2*1^2=2 electrons while the second holds 2*2^2= 8 electrons.
i think its theory but im not to sure
The correct statement is that the average kinetic energy of the gas particles is greater in container A because its particles move faster.
<h3>What is the relation between temperature & kinetic energy?</h3>
Kinetic energy of any particle is directly proportional to the temperature of the sample of that particle.
From the given diagram, it is clear that:
- In beaker A, heat is supplied to the beaker due to which temperature of the beaker A increases as a result of it particles of gases will move with faster velocity because kinetic energy of the gases particle increases.
- Beaker B is present at room temperature, so particles in this beaker will have less velocity as compared to beaker A.
Hence, the average kinetic energy of the gas particles is greater in container A because its particles move faster.

Answer:
Q= 0.21472 C
Explanation:
current is the rate of flow of charge through a wire or a circuit.
I = Q/t
Where I is current
Q is charge
t is time
Q=It
from the question, I=0.52 A , t=411 milliseconds
Q = 0.52 *411*
Q= 0.21472 C
Answer:
Cooling lowers the rate of the chemical reaction in the batteries.
Explanation:
When a battery is not in use and it may undergo some chemical changes which leads to decrease in its life (shelf life).
For example in case of Zinc battery, the zinc undergoes reaction with ammonia which deteriorate the cell or battery.
Now if we keep the battery in a cool place like refrigerator, the rate of chemical reaction will decrease (the rate of reaction generally decreases with decrease in temperature). Thus the battery stay fresh longer.
