Freezing temperature of rubber
WebIf 10 kg of oak is heated from 20 oC to 50 oC - a temperature difference 30 oC (K), the heat required can be calculated as. q = (2 kJ/kg K) (10 kg) (30 oC) = 600 kJ. If one hour (3600 s) is used to heat the oak - the power required can be calculated with the equation. P = q / t (2) WebBy freezing the automobile or truck tire in liquid nitrogen, the rubber is made brittle and can be crushed into small particles. These particles can be used again for other items.
