6. How would decreasing the temperature affect kinetic energy of molecules?
When the temperature of a substance decreases, it has a direct effect on the kinetic energy of its molecules.
B. 93 K =
C. 23°C =
C

7.Compare the average kinetic energies of solids, liquids, gases, and plasma.
Solids have the lowest kinetic energy so vibrate very little. Liquids have more kinetic energy so particles slide
past each other. Gases have the most kinetic energy so fly around in the air.Apr
8.What happens at absolute zero?
the temperature at which the particles in a substance are essentially motionless.
a. What temperatures are considered absolute zero? Ok
would contain atoms made up of free electrons and ions of the element.
