EXPLAIN:-
1) WHY DO ARABS WEAR LONG WOLLEN CLOTHES IN HOT DESERTS?
2) WHY DO WE DRINK TEA IN CHINA MUGS INSTEAD OF METALLIC MUGS?
Hi,
Woolen clothes have space in which they trap air. So when we sweat the air cools down. And woolen clothes do not allow the outside hot air to enter and touch our body. So, we sweat less and feel cool.
Metal is a good conductor of heat. If we put tea into the metallic cup, the heat transfer to cup and it becomes hot. We wouldn’t be able to hold it. Whereas, china mugs are made up of mud which is a bad conductor of heat i.e. it do not allow heat to travel. Thus its surface doesn’t get hot and we able to hold it.
Hope, the answers are clear to you now.
Best wishes!!
