1. Ramaya while going to school found his bicycle’s tyres to be little deflated. He went to a cycle repairing shop and overfilled his bicycle tube. On seeing this, the shopkeeper advised him that thisis not good for his cycle tube. But Ramaya overlooked shopkeeper’s advice and went to his school.
He kept his cycle in the cycle stand.
In afternoon when he came to take his cycle, he observed that its tyre has bursted. He got puzzled
why his tyres bursted though they were new.
(a) What is air pressure?
(b) What will happen if we use our bicycle with deflated tyres?
(c) Ramaya went to his school with overfilled tyre tubes but nothing happened to his tyres then.
Why did it burst when he was not riding and just kept it in cycle stand?
(d) What value of Ramaya is shown here?
Answers
Answer:
Answer (a) Air pressure is defined as the pressure exerted by the weight of air on the earth's surface. As we go up the layers of atmosphere, the pressure falls rapidly. The air pressure is highest at sea level and decreases with height.
Answer (b) First of all riding with a flat tyre means there's more surface area that tyre is connecting with which causes drag so you would need more power to get the bike moving and continue to move it. Also you wont get anywhere near as much speed either.
Answer (c) The temperature is maximum in afternoon and the heat of the sun warm the air inside the tube, thus rising its pressure to such an extent which caused the tyre to burst.
Answer (d) Ramaya is inexperienced, he overheard the advice of shopkeeper so he is disobedient also. He lacks scientific knowledge on expansion of air.
