Question

Why do we sweat? Relate your answer to the unique properties of water.
Describe an Exergonic and Endergonic reaction you've observed this week during your everyday activities

Answer 1

ANS)

* Simply we can say that sweat is the body's method of cooling you down.At the time when our body begin to feel that it's become too heat,its begin sweating as a method to regulate body temperature.Through advocating the heat loss by the way of evaporation,sweat support to control or manage the body temperature.

* The unique property of water which is shown during sweating is High heat of vaporization.

EXERGONIC REACTIONS

• The exergonic reaction is also known as spontaneous reaction.
• The exergonic reactions will discharge the energy to the environment.
• System's free energy reduces.The alteration in Standard Gibbs Free Energy of exergonic reaction will be below zero or negative.
• Examples involve, Combining sodium and chlorine to form table salt,Burning/ignition and emission of light at the time of chemical reaction.

ENDERGONIC REACTIONS

• Endergonic reactions are also known as nonspontaneous reaction.
• These reactions will absorb energy from its environment.
• System's free energy enhances.The alterations in Standard Gibbs Free Energy of the endergonic reaction will be more than zero or positive.
• Examples involve,Melting of ice to liquid water and photosynthesis.
