A student takes 50 g 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.

A

500 cal,`50^(@)C`

B

1000 cal, `100^(@)C`

C

1500 cal, `200^(@)C`

D

1000 cal, `200^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
C
From t =0 to t=1min
`DeltaQ = msDeltaT = 50/100 xx 06 xx 1000 xx(50 xx 0) = 1500 cal`
