a) molecules occupy negligible volume
b) molecules move randomly in straight line paths
c) molecules are not attracted to one another
d) molecules lose energy after colliding
e) molecules have the same kinetic energy at the same temperature

1. they vary with a higher number because boiling is way hotter than melting

what is the average time it took the car to travel 0.25 meters?

⇒ 2.23 seconds

what is the average time it took the car to travel 0.50 meters?

⇒ 3.13 seconds

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
