cavity of the intended shape.
Expendable mold casting can be classify as
sand, plastics, plaster which make use of non-reusable or temporary molds while Permanent mold casting is a metal
casting process that use reusable molds.
Collisions between all molecules increase as temperature increases. This is due to the increase in velocity and kinetic energy that follows temperature increases. ... This results in more molecules reaching the activation energy, which increases the rate of the reactions.
Explanation:
Where possible, we can switch to renewable sources of energy (such as solar and wind energy) to power our homes and buildings, thus emitting far less heat-trapping gases into the atmosphere.
