What is dry ice? Why is it so called? Give two uses of dry ice.
ACCELERATED PLANT GROWTH – A small quantity of CO2 will increase the growth rate of plants. Allow the dry ice to sublimate in close proximity to the plants for 10-15 minutes daily.
ASPHALT COOLING – Using dry ice allows for the delicate asphalt to stay at required temperatures during transport from the manufacturing plant to job site. Even more beneficial, using dry ice allows contractors to speed up the cooling process and core the paving sooner.
