Answers
Answer:
Ans 2) We should wear cotton garments in summer for the fact that during summers we generally sweat so much. ... Cotton fabric has a special characteristic that is a good absorber of water helps in absorbing the sweat and exposing it to the atmosphere for easy evaporation.
Ans 3) When we put some acetone or petrol or perfume on our palm, it evaporates. During evaporation, particles of the liquid absorb energy from the surface of the palm to compensate for the loss of energy, making the surroundings cool. The acetone, petrol or perfume take this latent heat of vaporisation from our palm.
Ans 4) Liquids changes into vapour by the process of evaporation. The factors that affect the rate of evaporation of liquids are temperature, surface area, wind speed, and humidity.
