Question

the lower energy level contains more atoms than upper level under the condition of .......​

Answer 1

The lower energy level contains more atoms than the upper level under the condition of thermal equilibrium.

• Thermal equilibrium suggests that when two bodies are taken into connection with each other and distinguished by a boundary that is absorptive to heat, there will be no transfer of heat from one to the other.
• Two physical operations are in thermal equilibrium if there is no net flow of thermal energy between them when they are attached in a way passable to heat. Thermal equilibrium fulfils the zeros law of thermodynamics.

Answer 2

Answer:

Thermal Equilibrium

Explanation:

Under the conditions of thermal equilibrium, the lower energy level contains more atoms than the upper level.

Thermal equilibrium is a relation between two bodies or closed systems, in which transfers are allowed only of energy and take place through a partition permeable to heat, and in which the transfers have proceeded till the states of the bodies cease to change.
