Ans 4:

Class : Class 4
d won't be the correct answer. the answer is c as air can be compressed.

Ans 5:

Class : Class 4
It will be D as it says that the jar contains 400 cm3 air and if a 50 cm3 syring filled with air is put into the jar it will become 450 cm3 400 50 = 450 cm3.

Vijay performed an experiment to compare the heat conductivity of four different materials P, Q, R and S. Thumbtacks were fixed with wax on each material and then the materials were fixed to a trough containing hot water as shown in the diagram.

Vijay tabulated his results as shown here.

What can be inferred from his experiment?

A Material R is a better conductor of heat than material S.
B Material S is a better conductor of heat than material R.
C Material Q is a better conductor of heat than material P.
D Materials P, Q, R and S are equally good conductors of heat.

(i) Milky Way is a spiral-shaped galaxy. --- Corrrect (ii) Planet Venus has 63 Moons. -------------Wrong ( it does not have moons) (iii) Satellites are small heavenly bodies that revolve around the Sun. --Wrong (they revolve around planets) (iv) One revolution of the Earth is completed in about 365 1/4 days. This time period is called a solar year. --Correct Therefore correct option is (A)

Ans 12:
