Answer:
Option (D) freezing point depression
Explanation:
Calcium chloride is added to the roadways after a snowstorm because it reduces the freezing point of the ice. Further more, it has been observed that the calcium chloride also produces enough heat which enhances the melting of the ice as it produces an exothermic reaction.
Momentum = (mass) x (velocity) = (1,100) x (30) =
33,000
kg-m/sec due east
Room temperature has the highest viscosity
