Question

9. Calculate the heat required to convert 3 kg of ice at -12° C kept in a calorimeter to steam
at 100°C at atmospheric pressure. Given specific heat capacity of ice = 2100 J kg K.
specific heat capacity of water = 4186 kg Klatent heat of fusion of ice = 3.35 X 1053 9.
kg and latent heat of steam = 2.256 x 106 kg. [Model paper, NCERT EXAMPLE] ]
10. A metal cylinder of length 0.05 m having its cross sectional am​

Answer 1

Answer:

A metal cylinder of length 0.05 m having its cross sectional area of

cylinder are kept at 3450 K and 2850 K. Calculate the amount of heat transmitted in 20

minutes from one end at higher temperature to the other end at lower temperature of the 9

cylinder. Given the thermal conductivity of metal cylinder is 419 Wm'k!. [DK-2013] 5.43X/DJ
