Answer the following question
1. Give 3 difference between evaporation and boiling
2. What is condensation and humidity
3. State the factor on which rate of evaporation depends
Answers
evaporation means the water turns into water vapour on boiling
boiling means just heating the water
condensation means turning of water droplets into water
humidity means water vapour into ice
it depends on the degree Celsius
Answer:
1)Evaporation occurs on the surface of the liquid whereas boiling occurs at the entire length of liquid. 2. Boiling occurs rapidly whereas evaporation occurs slowly. ... Evaporation occurs at any temperature whereas boiling occurs at a specific temperature.
2) Condensation will form on windows when the temperature of the surface of the glass (glazing), sash or frame is lower than that of the humid air surrounding it. The water vapour in the air changes to liquid when it comes into contact with these cold surfaces.
3)The rate of evaporation depends on surface area, temperature, humidity and speed of the wind. It increases with increase in surface area, temperature, and wind speed. But it decreases with increase in humidity.
