Question

Comment upon the following: rigidity,compressibility,fluidity,filling a gas container,shape,kinetic energy and density

Answer 1

1. rigidity-the tendency of a substance to maintain it's shape when subjected to outside force. compressibility-the property of gas due to which volume of a substance can be decrease by applying force.fluidity-the tendency of a particles to flow is called fluidity.liquid and gases are fluids.filling of a gas container-gases particles can move randomly in all the directions due to negligible intermolecular force between them. therefore the gas can fill the container.

Answer 2

rigidity - the hardness of any solid is called rigidity
compressibility - the ability of compression of solid liquid and gas are called its compressibility
fluidity - the ability flow of an liquid is called fluidity a liquid generally flow is easily .
filling a gas container - solid do not fill their container completely liquid also do not feel their container completely but a gas its container completely
shape - solid have a fixed shape of a liquid and gases take the shape of visil in which they kept.
kinetic energy - the energy possessed by a body due to its motion called Kinetic energy
density - the mass per unit volume of substance is called density.
