States of Matter
What state of matter has particles that move at high speeds and rarely interact with one another?
Gas
What is the difference between potential energy and kinetic energy?
Potential energy is the energy of an object at a certain position or condition and Kinetic energy is the energy of motion.
A baby potato has a temperature of 40 degrees and a regular-sized potato that has a temperature of 42 degrees. Which potato has more thermal energy?
The regular-sized potato.
If two objects are the same objects but have different size and temperature, then the one with the higher temperature has more thermal energy
What temperature do particles stop moving?
Absolute Zero
Particles that are super close together and have little movement are what state of matter?
Solid particles
What is the kinetic theory of matter?
That ALL particles in the three states of matter are ALWAYS moving
What is the BIG difference between thermal energy and temperature?
Temperature is the AVERAGE kinetic energy of an object and Thermal energy is the TOTAL kinetic energy of an object.
What is one difference between the three ways to measure temperature?
Kelvin is not measured in degrees
Fahrenheit is only used in 3 countries
The motion or movement of partciles of matter is always __________.
Random
The higher the kinetic energy and the higher the temperature. The lower the kinetic energy the lower the temperature.
I have one 4 lb squash and one 2 lb squash and I heat them up in the oven at 400 degrees. Which squash has more thermal energy?
The 4lb squash.
If two objects are the same object with the same temperature but a different size, then the one with more mass has more thermal energy
How can temperature be measured?
Fahrenheit, Celcius, and Kelvin
Which state of matter has particles tumbling over one another and are slightly far away from one another?
Liquid
Rank the three states of matter from GREATEST to LEAST kinetic energy and explain why.
Gas, Liquid, Solid
Because gas particles have more room to move around and move faster whereas solids have less room to move around and move slowly.
I have a can of pop and pizza in the fridge. Which object has more thermal energy?
The pizza.
If two objects are not the same objects, then the one with more mass has more kinetic energy.
What instrument is temperature measured with?
A thermometer
