Kindly give me both right solutions with explanations. 

What is the effect of increasing heat on the
tensile strength properties of a polymeric
material
There is a reduction in ultimate tensile
strength and decrease in the Youngs
modulus
There is an decrease in the ductility of
the polymer
There is an increase in the ultimate
tensile strength
There is a decrease in the stiffness
and an increase in the ultimate tensile
strength.
