If m is the minimum amount of steam of ...

If m is the minimum amount of steam of `100^(@)C` required to melt 12 gm ice completely, then find the value of 10cm.

A

1gm

B

2 gm

C

2.3 gm

D

1.5 gm

Text Solution

Verified by Experts

The correct Answer is:
D
Heat required = Heat supplied
` 12 xx 80 = m[540 + 1 xx 100]`
` m = (12 xx 80)/(640) = 1.5 gm `
