Question

State whether true or false :
Elasticity of a substance decreases with the increase in temperature.

• A. True
• B. False

Answer 1

The correct option is A True

The elasticity of a substance is defined by the modulus of elasticity. And, modulus of elasticity = $\frac{stress}{strain}$

As temperature increases, strain increases as molecular distance increases. So, modulus of elasticity decreases. Also, we can say, as elasticity is the measurement of the rigidity of a substance, so, as temperature increases, this rigidity decreases.
