_______is the thermal energy that flows from one substance to another when the
substances differ in temperature.
Heat
Isaac wants to make s'mores. He holds a marshmallow on a metal skewer over a
fire. A few seconds later, the marshmallow is cooked and the skewer feels warm.
What most likely happened?
Thermal energy in the form of heat moved from the fire to the skewer and marshmallow.

producing a lot of heat and is smoking. Where is the error in her statement?
Her computer is producing thermal energy, not heat.
Which best explains why water boils in a pot sitting over fire?
Thermal energy from the fire moves to the water in the form of heat.
If a cup of coffee is at 90°C and a person with a body temperature of 36°C touches
it, how will heat flow between them?
from the cup to the hand

inside the house and release it outside the house. What can be said about the
coils when they are accepting the heat inside the house?
They must be cooler than the air inside the house.
How do the metal aluminum coils in an air conditioner help keep a house cool?
They insulate the house from outside thermal energy. "NC"
They conduct thermal energy from inside the house and release it outside the house.
They insulate the surrounding air from indoor thermal energy.
They conduct thermal energy from outside the house and release it inside the house.
When Object 1 came into contact with Object 2, Object 2 got warmer. What can be
concluded about the objects before they came into contact with each other?
Object 1 had faster-moving particles.
How does a foam-filled winter coat help keep a person warm?
, It slows down the transfer of thermal energy from outside to inside the coat. "NC"
It slows down the transfer of thermal energy from inside to outside the coat.
It speeds up the transfer of thermal energy from outside to inside the coat.
It speeds up the transfer of thermal energy from inside to outside the coat.
Which describes how fast-moving particles assist in transferring thermal energy
to a cup after hot tea is poured into it?
They collide with slow-moving particles.
What must be true about two objects for conduction to take place?
The objects must be different temperatures and they must be in contact.
Conduction can occur within a single substance, but parts of the substance must
have which property?
different temperatures
different textures
different particle sizes "NC"
different colors
Conduction involves the transfer of electric charge or
thermal energy

The diagram shows the sun's interior. Convection currents are present in the
convection zone.
Which best describes how fluids change as they travel through different portions
of the convection currents?
They become more dense at the outer portion of the convection currents
Which area of Earth is most similar to the sun's convection zone?
the mantle

mixture for three minutes. When she takes the cup out, the handle is very warm.
Steam rises from the cup, so she blows it before taking a sip. In which part of this
scenario can convection be best observed?
rising steam from the cup of cocoa

Which best describes what is happening in the diagram?
At point 4, thermal energy from warm air over the land is transferred upward toward
cooler areas of the atmosphere
Water is boiling in a clear pot, as shown in the picture.
