Multiple Choice

Basic unit of matter; found in all living and non-living things

• atom

• cell

• electron

Multiple Choice

matter

• building block of everything

• anything that takes up space and has mass

• Total energy of motion in the particles of a substance

Multiple Choice

States of matter

• a molecule in which one side of the molecule is slightly negative and the opposite side is slightly positive

• The amount of mass per unit of volume

• the physical forms of matter, which include solid, liquid, and gas

Multiple Choice

Thermal Energy

• Energy transfer by the circulation or movement of a liquid or gas; heat rises, cold sinks

• Energy transfer from one substance to another substance when they are touching

• Total energy of motion in the particles of a substance

Drag and Drop

The energy an object has due to its motion is called ​ ​

Multiple Choice

Conduction

• Energy transfer by the circulation or movement of a liquid or gas; heat rises, cold sinks

• Energy transfer from one substance to another substance when they are touching

• Energy transfer by electromagnetic waves, can occur without contact through empty space

Multiple Choice

Convection

• Energy transfer by the circulation or movement of a liquid or gas; heat rises, cold sinks

• Energy transfer from one substance to another substance when they are touching

• Energy transfer by electromagnetic waves, can occur without contact through empty space

Multiple Choice

Radiation

• Energy transfer by the circulation or movement of a liquid or gas; heat rises, cold sinks

• Energy transfer from one substance to another substance when they are touching

• Energy transfer by electromagnetic waves, can occur without contact through empty space

Multiple Choice

Temperature

• basic unit of matter

• A measure of how hot or cold something is based on the average kinetic energy of the particles of a substance.

• The amount of mass per unit of volume

Multiple Choice

Energy can’t be created or destroyed; energy moves from high to low energy (heat flows to cold)

• Law of Thermodynamics

• Law of Conservation of Matter

• Conduction

• Polar Molecule

Multiple Choice

Polar Molecule

• a molecule in which one side of the molecule is slightly negative and the opposite side is slightly positive

• a very cold molecule

• basic unit of matter
