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
What does held nucleons together in a nucleus? Nuclear force. It is the nuclear force which fasten the nucleons together and is responsible for the stability of nucleus.

Define Heat Capacity Ratio? To find C p /C v of a gas, one occasionally uses the following method. A certain amount of gas with preliminary temperature T 0 pressure P 0 and
Biot-Savart law (J.B. Biot, F. Savart) A law defines the contributions to a magnetic field through an electric current. This is analogous to Coulomb's law. Mathematically spec
A small bulb is placed at the bottom of a tank containing water to a depth of 80 cm. What is the area of the surface of water through which light from the bulb can emerge out? Refr
how may six digit numbers can be made in which the sum of the digits is even?
Q. Explain basic working of Interference Filter? An interference filter, which reflects one of more spectral lines and transmits others, while maintaining a nearly zero coeffic
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)
