Basic Concepts of Matter and Energy

What is mass?

• amount of matter in object

• amount of space an object takes up

• anything that has volume

• objects packed tighter

What is volume?

• amount of matter in an object

• tightly packed "stuff"

• amount of space an object takes up

• made up of small particles known as atoms

What is density?

• made up of small particles known as atoms

• amount of matter in an object

• amount of space an object takes up

• how tightly packed the "stuff" (mass) is in a certain amount of space

What is higher density?

• anything that has mass and volume

• objects packed tighter

• amount of space an object takes up

• amount of matter in an object

What is the formula for density?

• D = m/v

• D = v/m

• D = m * v

• D = m/m

What is convection?

• causes energy to move from the warmer object to the cooler object

• movement of energy as light and heat

• movement of energy between objects that are touching

• movement of energy caused by the circulation and density

What is conduction?

• Boiling water is an example

• movement of energy between objects that are touching

• movement of energy caused by the circulation and density

• movement of energy as light and heat
