Question # 1

Q no 5 (B) How much would be the volume of ice formed by freezing 1 liter of water.

  • Ans 1: Data:
    Volume of water = V1= 1 liter Volume of ice on freezing=V2= ?
    Solution:
    As we know that Volume of ice/Volume of water =density of water/density of ice
    Volume of ice = density of water/density of ice x Volume of water
    = 1000/920 x 1
    = 109 liters Ans

Question # 1

State and explain Hook's law

  • Ans 1: Hook's law: the strain produced in a body by the stress applied to it is directly proportional to the stress with in the elastic limit of the body
  • Ans 2: Explanation; Hook's law is applicable to all kinds of deformation and all type of matter i.e. solids, liquids or gases within certain limit. This limit tells the maximum stress that can be safely applied on a body with out causing permanent deformation in its length volume or shape.
    In other words, it is a limit with in which a body recovers its original length, volume or shape after the deforming force is removed. When a stress crosses this limit, called the elastic limit, a body is permanently deformed and is unable to restore its original state after the stress is removed
