nothing, they would not change
both rooms would become hotter
both room would become colder
the bedroom temp. would lower and the living room temp. would rise
Hot things have ____________ thermal energy than cold things
more
less
same
potato
Objects with MORE MASS have______________
lower potential energy
lower number of atoms
higher thermal energy
higher temperature
Cold things often have a _________ kinetic energy because_______
lower; particles are moving around less
lower; particles are moving around more
higher; particles are moving around the same
higher; particles do not move
As temperature increases, molecules _____________
move slower
move the same
move faster
stop moving
Nash puts his cold Coke Slurpee on to the metal roof of his mom's car. Describe the heat transfer that takes place.
Heat is transferred from the car's roof into the Slurpee and increases the temperature of the Slurpee.
Heat is transferred from the Slurpee into the roof and increases the temperature of the roof.
The Slurpee stays the same temperature until it is completely gone.
The roof doesn't change temperature due to the fact that it sits in the sun all day.
If a substance has many particles and we want to increase the kinetic energy of it, then what will it need more of from the surroundings?
Mass
Volume
Energy
Conduction
What is thermal conductivity?
The rate at which particles move in a substance
The ability of a substance to have a large thermal energy
A factor that determines the amount of thermal energy of a substance
The rate at which a substance transfers heat
What is a conductor?
A material in which kinetic energy transfers easily
A material in which kinetic energy does not transfer easily
A material in which mass is transferred easily
A material in which mass is not transferred easily
An insulator
Transfers kinetic energy well
Transfers mass well
Does not transfer kinetic energy well
Transfers matter well
Which makes the best conductor
Water
Plastic
Wood
Aluminum metal
The energy of MOTION is called _______ energy.
thermal
kinetic
potenial
motion
A liquid thermometer works because liquid _______ when warmed.
expands
contracts
becomes a solid
condenses
The particles in the images are undergoing a change in energy. Which statement best describes what is happening?
The kinetic energy of the particles on the right is the greatest of the three types of particles.
The particles in the middle have more kinetic energy than the particles on the right.
The particles in the middle have less space between them than the particles on the left.
Energy was added to the particles on the left, so the particles in the middle have more energy.
In a(n) (a) , the particles are packed closely together, but they can move past each other freely.
The common state of matter that does not have a definite shape or a definite volume is a(n) (a) .
