How Does Temperature Affect The Bounce Of A Ball? - Blurtit

At high temperature the bounce of the ball increases as at high temp the energy of molecules is high.On impact it exerts greater pressure,so bounces back to greater height moreover at high temperature rubber become a bit soft and give some extra bounce.At low temperature the energy of molecules is less and ball is hard so its bounce decreases.

Viscosity The Physics Hypertextbook

Viscosity is first and foremost a function of material. The viscosity of water at 20 is 1.0020 millipascal seconds (which is conveniently close to one by coincidence alone). Most ordinary liquids have viscosities on the order of 1 to 1,000 mPa s, while gases have viscosities on the order of 1 to 10 ╬╝Pa s.

Temperature Effects on the Elasticity of Rubber Bands

The colored rubber bands in particular had the largest range between extreme stretch distances (5.4 cm 11.2 cm; range of 5.8 cm). This may have been caused by an ingredient in the dye, such as water, that altered the rubbers response to vulcanization.
