Heat and Thermal ExpansionHard
Question
Two substance A and B of equal mass m are heated by uniform rate of 6 cal s-1 similar conditions. A graph between temperature and time is shown in figure. Ratio of heat absorbed HA / HB by them for complate fusion is : -
Options
A.
B.
C.
D.
Solution
HA = (6 cal /s) × (6 - 2) s
HB = (6cal/s) × (6.5 -4)s
∴
HB = (6cal/s) × (6.5 -4)s
∴
