Thermal Energy Quiz

Thermal energy is best described as:

• The “heat energy” of an object, generated by the movement of particles inside of an object.

• The short, quick movement of particles back and forth

• A material that easily transfers heat

• Particle motion inside of a gas.

A material that does not easily allow heat to pass through is called a(n):

• Conductor

• Liquid

• Insulator

• Vibration

How can you recognize that thermal energy transfer has happened?

• temperature changes

• no changes

• new substances formed

How would you classify an object that keeps hands warm in the cold:

• a good insulator

• a good conductor

• a poor insulator

In the image below, ______ is a region of more heat since _______.

• Picture A; the particles are vibrating at a faster rate.

• Picture B; the particles are vibrating at a faster rate.

• Picture A; the particles are vibrating at a slower rate.

• Picture B; the particles are vibrating at a slower rate.

Which material would be the best conductor?

• Sheep wool

• Cookie Sheet

• Styrofoam Bowl

• Ceramic Mug

In the sphere image below, ______ would be considered to be most dense since:

• A is the most dense since the particles are packed closer together in a given space.

• B is the most dense since the particles are packed closer together in a given space.

• C is the most dense since the particles are packed closer together in a given space

• A, B and C are all of equal density since they are the same size sphere.

Double pane windows help to insulate homes since:

• There are two panels of glass, making the window extra dense.

• Air is contained between the glass panels which prevents thermal energy transfer since the particles are spread far apart.

• A liquid layer is contained between the glass panels which traps heat.

• The panels of glass allow air to move through them.

Which action would help a fireplace burning wood keep a room nice and warm during a cold winter day?

• Insulate the walls and ceiling

• Use single-paned windows

• Use light, sheer fabric as curtains on windows

• None of the above

Which is the best design of cooler to keep items cold on a warm summer day

• the walls of the cooler are made of two sheets of white plastic with a space of air in between

• The walls of the cooler are made of one sheet of lightweight metal

• The walls of the cooler are made of thick fabric

• The walls of the cooler are made of a single sheet of clear plastic
