How much steam at `100^@C` will just melt 64 gm of ice at `-10^@C`?

A

8.5 g

B

6.5 g

C

4.5 g

D

2.5 g

Text Solution

Verified by Experts

The correct Answer is:
A
`mL_S+ms_(omega)(100-0)`
`=m_("ice")xxS_("ice")[0-(-10)]+m_("ice")xx80`
`mxx540+mxx1xx100`
`=64xx0.5xx10+64xx80`
`640m=64xx85`
`m=8.5g`
