Construction has a big impact on the environment because A
the waste it creates fills landfills and waterways with a large amount of dangerous pollution.

B
it changes the way landscapes look, sometimes in ways that are not visually appealing.

C
it uses fertilizers and pesticides that kill certain organisms or makes some grow in larger than normal numbers.

D
it requires trees to be cut down, it takes up land that belongs to other organisms and it uses a lot of energy.

In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. which postulate of kinetic molecular theory best explains how this is possible? a. attractive forces between gas particles are negligible because the particles of an ideal gas are moving so quickly. b. collisions between gas particles are elastic; there is no net gain or loss of kinetic energy. c. gases consist of a large number of small particles, with a lot of space between the particles. d. gas particles are in constant, random motion, and higher kinetic energy means faster movement.
