Two different metal bodies A and B of equal mass are heated at a uniform rate under similar conditions. The variation of temperature of the bodies is graphically represented as shown in the figure. The ratio of specific heat capacities is:

  1. 83
  2. 38
  3. 34
  4. 43

Solution

ΔQΔtA=ΔQΔtB

mSAΔTΔtA=mSBΔTΔtB

SASB=ΔTΔtAΔTΔtB=90/6120/3=1540=38
