Answer 1

Answer:

(b) rubber is more porous than leather.

Answer 2

Answer:

People use rubber soles in their shoes because rubber is more porous than leather.

Explanation:

Why rubber soles are used in shoes?

• Rubber is more porous than leather.
• Due to pores in rubber, air can easily come and go through soles in shoes which produce less sweat in shoes.
• Also, rubber is soft and flexible in nature so minimal chances of breaking and comfortable to wear it in shoes.
• While in the case of leather, it is less porous so air can't pass through it which causes excessive sweating and it is hard and easily breakable.

So, people use rubber soles in shoes because of pores present in rubber.
