  Same quantity of ice is filled in each of the two identical metal containers P and Q having the same size and shape but of different materials. In P ice melts completely in time \( t_1 \), whereas in Q the time taken is \( t_2 \). Then the ratio of conductivities of P and Q is:

  • \( \frac{t_2}{t_1} \)
    
  • \( \sqrt{\frac{t_1}{t_2}} \)
    
  • \( \frac{t_2}{t_1^2} \)
    
  • \( \frac{t_2}{t_2^2} \)

  Calculate the number density of free carriers in silver, assuming that each atom contributes one carrier. The density of silver is \( 10.5 \times 10^3 \, \text{kg/m}^3 \) and the atomic weight is 107.8.

  • \( 0.585 \times 10^{28} \, \text{carriers/m}^3 \)
    
  • \( 58.5 \times 10^{26} \, \text{carriers/m}^3 \)
    
  • \( 585.0 \times 10^{27} \, \text{carriers/m}^3 \)
    
  • \( 5.85 \times 10^{28} \, \text{carriers/m}^3 \)
