Solution

32- b amount of energy requiered to raise the temperature of a unit mass of material by 1 degree centigrade is called as specific heat of that material. Denoted by \'C\' units Joule per kg per kelvin.

33-b permenant deformation of a material under a static load (that is load doesnot vary with time) over period of time is called as creep.

34-b

35-c

In Injection moulding molten material (polymers, glass) is injected to get the shape of mould. This process is used to produce thin sections with better dimensional accuracy.

Blow moulding: is used to produce hollow cavities in the shape as like bottles. This process requieres high pressure air to blow over mould cavity to obtain the shape to the material. This process is used for materials like Glass, plastic
