Explain the following:
Gases can mix up freely with one another.

Explain the following: Gases can be compressed by applying pressure on them.

Which of the following are isoelectronic with one another?

Explain the following: The north end of a freely suspended magnetic needle gets attracted towards a piece of soft iron placed a little distance away from the needle.

Explain the following: Several soft iron pins can cling, one below the other, from the pole of a magnet.

Can the following be a net for a die? Explain your answer.

Two gases can mix up together even against gravity.

Two ideal monoatomic and diatomic gases are mixed with one another to form an ideal gas mixture. The equation of the adiabatic process of the mixture is PV^(gamma)= constant, where gamma=(11)/(7) If n_(1) and n_(2) are the number of moles of the monoatomic and diatomic gases in the mixture respectively, find the ratio (n_(1))/(n_(2))
