FAQs on Applications of Heat Transfer: Kind of Clothes we wear in Summers and Winters Video Lecture - Science Class 7
| 1. What kind of clothes should we wear in summers? |  |
Ans. In summers, it is advisable to wear light and breathable clothes made of natural fibers like cotton or linen. These fabrics help in absorbing sweat and allowing air circulation, keeping the body cool and comfortable.
| 2. What kind of clothes should we wear in winters? | |
Ans. In winters, it is recommended to wear clothes that provide insulation and retain body heat. Layering is a good option, where multiple thin layers of clothing trap warm air between them. Fabrics like wool or fleece are excellent choices as they have good insulation properties.
| 3. Why do we wear light-colored clothes in summers? | |
Ans. Light-colored clothes reflect most of the sun's rays instead of absorbing them. As a result, they do not heat up quickly and keep the body cooler compared to dark-colored clothes. Light colors also help in reflecting light, reducing the heat absorbed by the fabric.
| 4. Why do we wear dark-colored clothes in winters? | |
Ans. Dark-colored clothes are known to absorb more heat from the sun and the environment. In winters, wearing dark-colored clothes can help in retaining the heat absorbed by the fabric, keeping the body warmer. This is especially beneficial in cold weather conditions.
| 5. Why is it important to wear breathable clothes in summers? | |
Ans. Wearing breathable clothes in summers allows air to circulate around the body, promoting sweat evaporation and heat dissipation. This helps in cooling down the body temperature and preventing overheating or discomfort. Breathable fabrics like cotton or linen are highly recommended for their moisture-wicking properties.
