A student takes 50gm wax (specific heat = 0.6 kcal/kg°C) and heats it till it boils. The graph between temperature and time is as follows. Heat supplied to the wax per minute and boiling point are respectively
Text Solution
Verified by ExpertsThe correct answer is:
C
Since specific heat = 0.6 kcal/gm × × °C = 0.6 cal/gm × × °C
From graph it is clear that in a minute, the temperature is raised from 0°C to 50°C.
⇒ ⇒ Heat required for a minute = 50 × × 0.6 × × 50 = 1500 cal.
Also from graph, Boiling point of wax is 200°C.
