2 Kg of ice at -20 degree C is mixed with 5Kg of water 20 degree C in an insulating vessel having negligible heat capacity. Calculate the final mass of water remaining in the comtainer. It is given thet the specific heats of water and ice are 1Kcal/kg/degree C and 0.5Kcal/kg/degree C while latent heat of fusion of ice is 80 kcal/kg

Q. Explain how Newton's ring can be obtained in the laboratory. Why Newton's rings are circular in shape? How the Newton's rings are used to find refractive index of liquid?
how to you calculate the inducatnce on a balanced delta circuit?
Apply the formula of mcT and at first calculate the amount of heat losed by water at 0 degree.the calculate the amount of heat gained by ice to go to 0 degree.now subtract the second from the first to get heat left for absorption.equate this heat to (mL)=latent heat ...and get the mass of new water formed.you will get it as 1 kg.hence the ans is 5+1=6 kg(ANS)
