physical situation Two heat conducting pistons can slide without friction in a horizonta made of a heat insulating material Distance between the pistons is 80 The space between the pistons is completely filled with water Dens water and ice are 1000 kg m and 900 kg m respectively specific h water and ice are 4200 J kg C and 2100 J kg C respectively latent heat of fusion of ice is 330 kJ kg and thermal conductivity four times of that of water Heat capacity of the pistons and that of the pip negligible are 26 The left and the right pistons are maintained at constant temperature 40 C and 16 C respectively After a sufficiently long time when steady state is reached what will the distance between the pisto become a 80 5 cm c 88 0 cm b 84 2 cm d 97 5 cm 27 Now the devices maintaining temperatures of the pistons are remov and the pistons are covered with heat insulating materials Afte sufficiently long time when a steady state is reached again what the distance between the pistons become a 80 0 cm c 89 2 cm b 88 9 cm d 92 7 cm
