Why do solids and liquids make better conductors than gases?
Collisions occur more frequently between particles of solids and liquids.
Collisions occur more frequently between particles of gases.
Collisions do not occur between particles of solids and liquids.
Gases convert more thermal energy into electrical energy.
Why does radiation usually pass through gases more easily than through solids or liquids?
Radiation is delayed every time it interacts with a particle of matter. Gases have less particles to delay the radiant energy.
Radiation needs particles to be able to travel, gases provide the most particles to be able to transfer energy between.
The increased mass in gases make it easier for the heated particles to move around the cooler particles.
Radiation is absorbed by particles and gases and more quickly transmitted than in solids or liquids.
Which is temperature most directly related to?
kinetic energy
mechanical energy
potential energy
thermal energy
