3600 calories

Explanation:

To convert 5 gm of ice at zero degrees to 5 gm of water of zero degrees,heat required will be #(m*l)# calories or# (5*80)# calories or 400 calories
Now to convert 5 gm water at zero degrees to 5 gm water at 100 degrees heat required will be #(m*s*theta)# or 500 calories.
And to convert the same amount to corresponding steam at 100 degrees will be #(M*l)# i.e#(5*540) calorie or 2700 calories
Hence total heat required for the full conversion is (400+500+2700) calories or 3600 calories
