Thermal Energy Quiz Supplemental (Atomic Structure, Heat Transfer, Density)

Heat energy from the sun is transferred to Earth by:

• conduction.
• radiation.
• convection.
• insulation.

Heat CANNOT travel by conduction through a:

• vacuum
• gas
• liquid
• solid

Air spaces between the feathers of a down-filled coat cause the coat to be a good thermal:

• convector.
• conductor.
• radiator.
• insulator.

Of the following, the GREATEST amount of thermal energy would be contained in:

• an ice cube.
• a room full of air at 100°C.
• a cup of hot chocolate.
• the North Atlantic Ocean.

Objects with a high density have:

• a large volume for their mass.
• a small volume for their mass.
• a large volume for their temperature.
• a small volume for their temperature.

The density of an object depends on which of the following?

• a. How closely the atoms or molecules are packed in the material
• b. The size of the object
• c. The mass of each atom or molecule that makes up the material
• d. Both A and C

How does the density of a thin silver wire compare to a silver ring?

• It is higher.
• It is lower.
• It is the same.
• You can’t tell without the numbers.

What is the density of a metal ring that has a volume of 3.10 cm³ and a mass of 60 g?

• 0.5 g/cm³
• 4.65 g/cm³
• 19.3 g/cm³
• 21.7 g/cm³

A particle with zero charge found in the nucleus of an atom is called a(n):

• electron.
• proton.
• neutron.
• positron

Electrons are held in place outside the nucleus by:

• electromagnetic force.
• gravitational force.
• strong nuclear force.
• weak force.
