Question

How much energy is transnferred when 1gm of boiling water at 100 c cools to water at 0c

Answer 1

Mass of water = 1 gram
Initial Temp. (T1)= 0 c
Final Temp. (T2)= 100 c

Specific heat of H₂O = 1cal /g-c
Heat Energy supplied (Q)= ms (T2-T1)
                                        = 1x1x(100-0)
                                        = 100 cal ← (Answer)

Good Studies!
