360322 The core of the sun is a plasma. It is at a temperature of The order of \(10^{7} {~K}\) and contains equal number of protons the electrons. The density of the core of the Sun is \(10^{5} {~kg} {~m}^{-3}\) Assume that molar mass of proton is \(1 {~g} {~mol}^{-1}\) and the mass of an electron to be negligible compared to the mass of a proton. Estimate the pressure at the core of the sun. Assume that plasma behaves like an ideal gas.

360326 A thermally insulated vessel contains an ideal gas of molecular mass \(M\) and ratio of specific heats \(\gamma\). It is moving with speed \(v\) and it's suddenly brought to rest. Assuming no heat is lost to the surrounding, its temperature increases by

1 \(\dfrac{(\gamma-1)}{2 \gamma R} M v^{2} K\)
2 \(\dfrac{\gamma M^{2} v}{2 R} K\)
3 \(\dfrac{(\gamma-1)}{2 R} M v^{2} K\)
4 \(\dfrac{(\gamma-1)}{2(\gamma+1) R} M v^{2} K\)
