100
The measure of average kinetic energy of particles in a substance.
What is temperature?
100
This tool measures temperature.
What is a thermometer?
100
A jacket is a good example of this, because it traps your body heat to keep you warm.
What is an insulator?
100
Energy from the sun travels to Earth in the form of:
What is radiation/ radiant energy
100
Temperatures flow from ______ to ______.
What is warmer to cooler?
200
This is the transfer of energy in the form of electromagnetic waves.
What is radiation?
200
Thermal energy and Heat are both measured using these:
What are Joules?
200
These types of materials make the best conductors of heat.
What are metals?
200
Convection usually occurs in these two states of matter.
What are liquids and gases?
200
Describe how particles are spaced in a solid object.
What is close together?
300
The total energy of all particles in an object.
What is thermal energy?
300
The SI unit for temperature.
What is Kelvin?
300
Heat flow is slowed or stopped in insulators. Explain in one sentence how this process works.
An insulator blocks convection currents, conduction and radiation from transferring heat from one place to another.
300
When grilling a hamburger, this is the type of heat transfer that takes place between the metal and the meat.
What is conduction?
300
When you feel the heat from a campfire, heat is being transferred using this type of heat transfer.
What is radiation?
400
The amount of energy required to raise the temperature of 1 kg of material 1 K.
What is specific heat?
400
Particles of objects in this state of matter move quickly.
What is a gas?
400
Identify and describe a good insulator. Make sure you explain why it makes a good insulator.
Many responses possible.
400
A space heater uses convection to circulate air through the room. Describe this process in terms of warm and cool air and how it rises and falls.
The space heater heats the air around it. The hot air rises and runs along the ceiling. As it cools, the air sinks to the floor. When it gets back to the space heater the cycle continues.
400
Describe what would happen to a wave or radiant energy that hits a shiny cellphone case.
Because the case is shiny, most of the energy will be reflected away in many directions.
500
The transfer of heat from one particle of matter to another within an object or between two objects.
What is conduction?
500
Two cups, one with hot and one with cold water, are placed next to each other connected only by a metal bar. Identify and explain the type of heat transfer that occurs.
What is conduction? The metal bar transfers the heat from the hot water to the cold water. Eventually, the temperatures in both cups will reach equilibrium.
500
Identify and describe an insulator and how it worked to block heat from being transferred.
Many correct responses possible
500
You are making a pot of soup using a metal spoon. You notice that the spoon was not hot, but now it is too hot to use. Identify the type of heat transfer at work and how it made the spoon hot.
Conduction. The heat from the hot soup transferred to the particles in the spoon. When it got to the end of the spoon, it also heated up the particles in your hand.
500
Describe how a thermometer is able to measure temperature.
A thermometer works by utilizing the expansion of particles in a substance. As the alcohol heats up, its particles move faster and spread apart, cause it to move up the thermometer. The number where the expansion stops is the correct temperature.
