Question

please give the ANSWER on your own don't copy from internate..

I am having my physics class test on Saturday.. if I will copy from net that sir will kill me .. ​

Answer 1

a Liquids and gases show only cubical expansion, but no linear and superficial expansion because they do not have a definite shape. Different gases have the same rate of expansion for the same rise in temperature, as compared to solids and liquids which show different rates of expansion for the same rise in temperature .

b Bottles have place for gas . ... As a result solubility of gases decreases. It require some space . If the bottles are fully filled then it may blast due to excessive pressure formed by increased kinetic movement or temperature .

Answer 2

Answer:

1. Liquids and gases show only cubical expansion, but no linear and superficial expansion because they do not have a definite shape.

2. Considerable space is left in medicine bottles to allow space for expansion when they are sent from cold to hot conditions.

ALL THE BEST FOR YOUR CLASS TEST!!!
