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

`500cal`, `50^@C`

B

`1000cal`, `100^@C`

C

`1500cal`, `200^@C`

D

`1000cal`, `200^@C`

Text Solution

Verified by Experts

The correct Answer is:
C
From `t=0` to `t=1min`
`DeltaQ=msDeltatheta=(50)/(100)xx0.6xx1000xx(50xx0)`
`=1500cal`
