With a rise of temperature, the Young’s modulus :

With the rise of temperature the Young's modulus of elasticity:

Young's modulus is

What is the effect of change in temperature on the Young's modulus ?

The unit of Young’s modulus is

The young's modulus of air is

The Young’s modulus of the material of the wire of length L and radius r is Y N//m^2 . If the length is reduced to L/2 and radius to r/2, the Young's modulus will be

If the temperature of the wire is increased, then the Young's modulus will
