Physical Science Honors: Matter and Energy
Terms in this set (17)
Anything that has mass and takes up space
All matter is made of...
Kinetic Theory of matter
1. All matter is made of particles that are in constant motion.
2. The faster particles move, the higher the temp of the substance.
3. At the same temp, more massive particles move more slowly than less massive ones.
Something DOES NOT change
Something CAN change
*Particles vibrate in place, move slow
*Cannot change shape easily
*Particles can move past each other, move quickly
*Particles are far apart, move very quickly
*made up of electrically charged, or ionized, particles
A state of matter in which the particles are free to move past each other (Liquid, Gas, Plasma)
The ability to change or move matter
The energy of motion
All particles in a material ____ move at exactly the same speed
a measure of the average kinetic energy of the particles
The higher the average kinetic energy of the particles...
The higher the temp
The total kinetic energy of all the particles in a substance.
A scientist has two samples of a substance. Both samples have the same temp. One sample has a mass of 10 g. The other has a mass of 20 g. Compare the average kinetic energy and the total kinetic energy of the particles in each sample
*Both substances have the SAME average kinetic energy.
*The 20 g substance has more total kinetic energy because it has more mass.
