1.	Two thin blankets keep more hotness than one blanket of thickness equal to these two. The reason is(a) Their surface area increases(b) A layer of air is formed between these two blanketswhich is bad conductor(c) These have more wool(d) They absrob more heat from outside
Answer» TION:Two THIN BLANKETS usually warmer than one thick blanket because air is trapped between them. And the air is BAD conductor of heat. It does not pass heat from our body to the surroundings.hence b option is correct ✌☇⚡☃
