Modes of Thermal Energy Transfer
This mode of thermal energy transfer occurs when two solids are in contact with one another
What is conduction
This is the measurement of the speed of the particles in a substance on average
What type of energy is stored within the molecular bonds within food?
Chemical energy
What are particles always doing even in a solid?
What is vibrating or moving.

Thermal energy
What has more energy when sitting on a shelf: a bowling ball or a feather?
Bowling ball
Why does a frozen lake have more thermal energy than a hot block of metal?
Because it has so many more particles.
What is the variable that you measure?
What is the dependent variable
Is an ice cube radiating thermal energy?
Yes
How is heat different from thermal energy?
Heat is the movement of thermal energy - not the thermal energy itself.
What is the starting and finishing type of energy that is involved in sunlight hitting a plant and the plant making sugar out of the sunlight?
Radiant/Light -> Chemical
How does energy get transferred between particles?
Collisions.

What are radiation, conduction, convection
373 K
When you open a refrigerator inside of a closed room, why does the temperature of the room increase?
How come solids are generally better conductors of thermal energy when compared to gasses?
Because their molecules are closer together.
How many miles are between the Earth and the Sun?
