The thermal capacity of 40 g of aluminium (specific heat `=0.2 cal//gm^(@)C`)

A

`168 J//""^(@)C`

B

`672 J//""^(@)C`

C

`840 J//""^(@)C`

D

`33.6 J//""^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
D
Thermal capacity `= ms = 40 xx 0.2 = 8 "cal"//""^(@)C`
`=4.2 xx 8 =33.6 J//""^(@)C`
