उत्तर

On the surface of the sun, T = 6000 K

Average thermal energy = `3/2` kT

`= 3/2 xx 1.38 xx 10^(-38) xx 6000`

`= 1.241 xx 10^(-19)` J

Hence, the average thermal energy of a helium atom on the surface of the sun is 1.241 × 10–19 J.

The figure shows the plot of PV/versus Pfor 1.00×10–3 kg of oxygen gas at two different temperatures.

(a) What does the dotted plot signify?

(b) Which is true: TT2 or T1 < T2?

(c) What is the value of PV/where the curves meet on the y-axis?

(d) If we obtained similar plots for 1.00 ×10–3 kg of hydrogen, would we get the same value of PV/at the point where the curves meet on the y-axis? If not, what mass of hydrogen yields the same value of PV/(for low pressure high temperature region of the plot)? (Molecular mass of H= 2.02 u, of O2 = 32.0 u, = 8.31 J mo1–1 K–1.)
