The temperature of 100g of water is to be raised from `24^@C` to `90^@C` by adding steam to it. Calculate the mass of the steam required for this purpose.

Text Solution

Verified by Experts

The correct Answer is:
A, B
Heat lost by steam=Heat gained by water
`m_sL_(fus)=m_wcDeltaT`
`rArrm_s=(m_wcDeltaT)/(L_(fus))=(0.1xx4200xx66)//(540xx10^3xx4.2)=0.0122 kg`
