# A beaker of water at 400 ° C(on the left in the drawing) and a beaker of ice water at 0 ° C are placed side by side in an insulated container. After some time has passed, the temperature of the water in the beaker on the left is 30 ° C and the temperature of the ice water is still 0 ° C. Describe what is happening in each beaker (a) on the molecular level and (b) in terms of the second law of thermodynamics.

## A beaker of water at 400 ° C(on the left in the drawing) and a beaker of ice water at 0 ° C are placed side by side in an insulated container. After some time has passed, the temperature of the water in the beaker on the left is 30 ° C and the temperature of the ice water is still 0 ° C.Describe what is happening in each beaker (a) on the molecular level and (b) in terms of the second law of thermodynamics.

Interpretation Introduction

Interpretation:

A beaker of water at 40°C (on the left in the drawing) and a beaker of ice water at 0°C are placed side by side in an After some time has passed, in an insulated container. After some time has passed the temperature of the water in the beaker on the left is 30°C and the temperature of the ice water is still 0°C. Description needed, that what is happening in each beaker (a) on the molecular level and (b) in terms of the second law of thermodynamics.

Concept introduction:

As the second law of thermodynamics states that for an isolated system, the entropy of the whole world will always grow with the time, and the entropy of the universe cannot be negative.

Entropy is a quantity of the inaccessible power in a closed thermodynamic arrangement which is also usually contemplated to be a quantity of the disorder of the system, which is a characteristic of the state of the system, and that varies sharply with any reversible alteration in heat in the system and inversely with the temperature of the system; generally: the degree ofinstability or disorder in a system.

a. What is happening in each beaker on the molecular level.

### Explanation of Solution

The transmission of Heat takes place from higher temperature to lower temperature while molecular contact. The heater molecules communicated its kinetic energy to the molecules of ice. This process lasts till the temperature gradient becomes zero...

Interpretation Introduction

b. What is happening in each beaker in terms of the second law of thermodynamics.
