Concept: Below its critical temperature ($T_c$) a superconductor becomes a perfect diamagnet.

1. In the Meissner effect the magnetic field is completely expelled from the interior of the superconductor.
2. Surface currents create an opposite field, so field lines bend around the material (see figure).

Yaad rakhein: Meissner = 'field out', $\chi =-1$ (perfect diamagnetism).

Answer: (B) Magnetic fields are completely expelled from the interior of the material.

Answer: (A) .potx

Concept: The triple point is the unique temperature and pressure at which ice, water and water vapour coexist in equilibrium.

2. $0^{\circ }\text{C}$ is the normal melting point; $-{273.15}^{\circ }\text{C}$ is absolute zero.

Yaad rakhein: Triple point $=273.16\text{K}={0.01}^{\circ }\text{C}$ – just $0.01$ above the ice point.
