Question

9. Which property of cotton makes it suitable for use as clothing in summer?
10. Which gas is used in fridge and in air conditioner and produced gas which affect ozone layers​

Answer 1

9) During summer, cotton clothes are preferred because cotton has good absorbance property. Therefore, when we sweat during summer's then cotton readily absorbs the moisture caused by sweating.

10)Refrigerator Disposal Releases Ozone-Depleting Chemicals. Summary: Shredded foam insulation from junked refrigerators is releasing substantial amounts of ozone-depleting chlorofluorocarbons, or CFCs, into the earth's atmosphere — and the more finely shredded the foam, the faster the release, a Danish researcher reports ...

Answer 2

BONJOUR MATE!!

1.

• During summer, cotton clothes are preferred because cotton has good absorbance property.
• Therefore, when we sweat during summer's then cotton readily absorbs the moisture caused by sweating.
• As a result, it provides a cooling effect after the absorbance.
• Moreover, cotton clothes are soft and provide better circulation of air to the body.
• Hence, all these properties of cotton makes it suitable for use as clothing in summer.

• Refrigerant gas is a chemical product used in refrigerators, freezers, air conditioners and heating, ventilating and air conditioning units (HVAC).
• These gases, which have very low evaporation points, are condensed under pressure to chill the air.
• Through a process of repeatedly evaporating and condensing the gasses, heat is pulled out of the air and the temperature inside the room or unit is reduced.
• Different types of refrigerant gases include chlorofluorocarbon (CFC), hydro chlorofluorocarbon (HCFC), hydro fluorocarbon (HFC), per fluorocarbon (PFC), and blends made from ammonia and carbon dioxide.
