Question
250 g of water and an equal volume of alcohol of mass 200g are placed successively in the same calorimeter and cools from 60oC to 55oC in 130 sec and 67 sec respectively. If the water equivalent of the calorimeter g then the specific heat of alcohol in cal/goC is : -
Options
A.1.30
B.0.67
C.0.62
D.0.985
Solution
Rate of cooling of water = Rate of cooling of alcohol
⇒
⇒ Specific heat of alcohol
s = 0.62
Rate of cooling of water = Rate of cooling of alcohol
⇒
⇒ Specific heat of alcohol
s = 0.62
⇒
⇒ Specific heat of alcohol
s = 0.62
Rate of cooling of water = Rate of cooling of alcohol
⇒
⇒ Specific heat of alcohol
s = 0.62
