Q. 3.47 - An Introduction to General, Organic, and Biological Chemistry

Question

Identify each of the following changes of state as evaporation. boiling, or condensation:

a. The water vapor in the clouds changes to rain.

b. Wet clothes dry on a clothesline.

c. Lava flows into the ocean and steam forms.

d. After a hot shower, your bathroom mirror is covered with water.

Step-by-Step Solution

Answer

(a) The water vapor in the clouds changes to rain is a reaction of Condensation.

(b) Wet clothes dry on a clothesline is a reaction of Evaporation.

(c) Lava flows into the ocean and steam forms is a state of Evaporation.

(d) After a hot shower, your bathroom mirror is covered with water is a reaction of Condensation.

Step1: Given Information (part a).

To find the reaction of The water vapor in the clouds changes into rain.

Step2: Find the reaction of water vapor in the clouds changes to rain (part a).

The reaction of  water vapor in the clouds changes to rain is a reaction of Condensation.

Condensation :

Condensation is the process of turning water vapor into liquid water, and the finest example is those huge, fluffy clouds floating above your head. Whenever the water droplets in clouds mix, they become heavy enough to pour down on your head.

Step3: Given Information (part b).

To find the reaction of Wet clothes dry on a clothesline.

Step4: Find Wet clothes dry on a clothesline (part b).

The reaction of Wet clothes dry on a clothesline is called as Evaporation.

Evaporation :

Evaporation is caused by heat, which is required to separate water molecules from one another.

Step5: Given Information (part c).

To know the reaction of Lava flows into the ocean and steam forms.

Step6: Lava flows into the ocean and steam forms (part c).

Lava flows into the ocean and steam forms is known as Evaporation. 

It's the result of evaporation. Because boiling refers to a liquid boiling at 100 degrees Celsius, but when lava flows into the ocean and steam emerges, the temperature is not 100 degrees Celsius, hence the right answer is evaporation.

Step7: Given Information (part d).

To find the reaction of the following:

After a hot shower, your bathroom mirror is covered with water 

Step8: After a hot shower, your bathroom mirror is covered with water (part d).

After a hot shower, your bathroom mirror is covered with water is the function of Condensation 

Your bathroom mirror is splattered with water after a hot shower. It's because hot vapors that come into contact with the mirror's comparatively cooler surface condense and create droplets.
