Choose the correct statements about 'Internal energy'
Internal energy is measured in Joules (J)
Internal energy is all of the energy of movement of the particles in a substance
Internal energy is the same as temperature
Increasing temperature will increase the internal energy of a substance
Internal energy is measured with a thermometer
True
False
Describe the energy transfer occuring in the picture
The cold is going from the environment to the tea
The cold is going from the tea to the environment
The heat is going from the tea to the environment
The heat is going from the environment to the tea
What will happen to the temperatures of the tea and the room in this picture if you left the tea out all day?
The temperature of the tea and the room will increase
The temperature of the tea and the room will decrease
The temperature of the tea will increase and the temperature of the room will decrease
The temperature of the tea will decrease and the temperature of the room will increase
Why does the temperature of a liquid decrease during evaporation?
All of the particles turn from liquid to gas
The fastest particles turn from liquid to gas
Random particles turn from liquid to gas
The slowest particles turn from liquid to gas
What are possible ways of transferring energy?
Evaporation
Radiation
Conduction

Based on this infrared image here, select which statement(s) are TRUE
The top of the tea pot is hotter than the bottom of the tea pot
The hand holding the tea pot is emitting radiation energy
The water being poured is hot
the bottom of the tea cup is hotter than the bottom of the tea pot
Conduction transfers energy by...
Emitting energy
the fastest particles moving from the liquid to become a gas
particles vibrating and hitting into each other
The change in density that occurs during conduction moving the substance to a different place
Conduction happens best in solids because...
The particles in solids are closer than the particles in liquids and gases
The particles in liquids are unable to vibrate
Gases are too light to do conduction
Gases and liquids do not have particles
Convection can occur...
In a gas
Where two solids are touching
Without contact
In a liquid
The difference between a thermal conductor and a thermal insulator is...
How well the substance turns from a solid to a liquid
How well the substance transfers heat energy
How well the substance reacts with fire
How well the substance changes state
The same material can be used as a thermal insulator to keep hot things hot and to keep cold things cold
True
False

When the light is turned ON...
The black thermometer's temperature will increase more quickly.
The white thermometer's temperature will increase more quickly.
Neither thermometers's temperature will increase.
Both thermometers's temperatures will increase at the same speed.
