Matter
What is Matter?
Anything that has mass and takes up space.
Which has more thermal energy? A cup of hot tea or an iceberg? Why?
An iceberg. It contains more heat because it's bigger.
What are conductors?
a material that easily allows the flow of heat
What are the 3 types of heat transfer?
Conduction, Convection, Radiation
transfer thermal energy very quickly
Thermal conductors
What is Heat Transfer?
Thermal Energy exchanges between objects of different temperatures
Thermal energy always moves from objects with _______ temperatures to objects with ________ temperatures.
Higher
Lower
Insulators _______ thermal energy transfer.
Minimize
The transfer of energy by the movement of electromagnetic waves.
Radiation.
True or False: The transfer of energy drives the movement of matter within a system and between systems.
True
True or False: Energy and matter can be created and destroyed.
False. Energy and matter cannot be created or destroyed.
All of the matter in the same location
Environment
If two objects have different temperatures, in which direction will heat move? For how long?
From warm to cold until both temperatures have leveled out.
Can only happen in liquid and gases. Heat transfer that is caused by the rising of hotter, less dense fluids and the falling of cooler denser fluids.
Convection
Heat transfer through a fluid
What is Convection?
the energy of motion is known as
kinetic energy
Define Thermal Energy.
The total kinetic energy of tiny particles that make up matter.
Define Temperature.
The average kinetic energy of all the particles in a material.
The transfer of thermal energy that occurs in solids, liquids, and gases when 2 substances of different temperatures touch.
Conduction.
Amount of matter in an object, which affects energy transfer
Mass
