Physics Questions

Tensional forces normally cause normal faults.

The flow of thermal energy due to differences in their temperatures is called Heat.

Energy can be transferred from one system to the other. The rate at which energy is transferred from one system to other system is called POWER. Energy transferred in one second is called a watt.

We know that, solids have definite shapes and definite volumes, whereas liquids have definite volumes but indefinite shapes and coming to gases it has indefinite volumes and indefinite shapes.

Hence, only in solids, the forces of attraction limit the motion of particles.

Graphite is a good conductor of electricity as it contains free electrons to move through the structure of the graphite.

Resistivity :

Resistivity is a measure of the resistance to the flow of electrons. 

Conductivity :

Conductivity is just the inverse of resistivity, σ = 1/ρ, where σ is conductivity and ρ is resistivity.

Example:

Think of a pipe and water, the bigger the pipe, the easier water can flow and thus the lower the resistance. 

The combined gas law states that the ratio between the pressure-volume product and the temperature of a system remains constant.

Hence it depends on all the three Volume, Temperature & Pressure.
