Collect information about places where we get coal, petroleum and natural gas in India and mark the places on outline map of India. `(AS_(5))`

Collect information about temperature recorded a various places in India in the month of January and write them using integers.

collect information about the main food habits of different states of India. Refer the atlas,liberary books and discuss with your teacher.

Visit your school library or internet, collect information about (kashmir) Dal Lake regarding in which season water in the lake becomes ice and snow fall is very high and why the place attracts more tourists.

At where the object is placed, on principal axis of a concave mirror, we get the image at infinity

The root mean square speed of an ideal gas is given by : u_("rms") = sqrt((3RT)/M) Thus we conclude that u_("rms") speed of the ideal gas molecules is proportional to square root of the temperature and inversely proportional to the square root of the molar mass. The translational kinetic energy per mole can also be given as 1/2Mu_(rms)^(2) . The mean free path ( lambda ) is the average of distances travelled by molecules in between two successive collisions whereas collision frequency (C.F.) is expressed as number of collisions taking place in unit time. The two terms lambda and C.F. are related by : C.F = (u_("rms")/lambda) A jar contains He and H, in the molar ratio 1 : 5. The ratio of mean translational kinetic energy at the same temperature is
