• ## Question: How do gas exerts pressure on the walls of container?

Posted in: Chemistry | Date: 08/05/2018

Gas consists of molecules which are in random motion . These gas molecules are free to move as there is very very less force of attraction among gas molecules. These randomly moving gas molecules collide with the wall of container. When molecules collide continually with wall , though they collide with each other also , they exert force on wall. A gas molecules apply a little force on some area of the wall . There is a large number of gas molecules colliding continually with wall. Total force on the wall is sum of all these small forces by molecules. And pressure is defined as force per unit area. Therefore total force by molecules divided by area is the pressure exerted by gas on wall .

• ## Question: Why do we wear light coloured clothes in summer?

Posted in: Physics | Date: 08/05/2018

We prefer to wear light coloured clothes in summer as light colours reflect light and heat and as a result of which light coloured clothes absorb less heat and become less hot giving us relief in summers. On the other hand dark colours absorb more light and heat and they become hotter and give us restlessness/ donot help us keeping cool in summer. Thats why we should wear light coloured clothes in summer and dark coloured clothes in winter.

• ## Question: A body travels a distance of 15m from A to B and then moves distance of 20m at r...

Posted in: Physics | Date: 29/05/2018

We will use Pythagoras theorem to find both distance and displacement. A right angled triangle is formed with base AB=15m and height 20 m. By Pythagoras theorem, 15^2 +20^2 = 225+400=625 Now Hypotenuse is square root of 625 i.e. 25 Now 25 m is the displcement . And distance is 15+20=35m

• ## Question: Why does 22-carat gold used in making ornaments?

Posted in: Chemistry | Date: 22/03/2019

24 carat gold is pure gold. Gold is highly malleable and ductile and is very soft metal. It is difficult to make ornamental designs with 24 carat soft gold. So by alloying 22 parts gold and with 2 parts silver/copper , 22 carat good is formed. It is comparatively harder and designs can be made due to its malleability and ductility. 22 carat good can easily be carved into different designs easily.
