Thermal Energy Transfer

Question 1

Thermal energy

Answer 1

is the energy an object has because of the movement of its molecules and heat can be transferred from one object to another object

Question 2

Temperature

Answer 2

is a measurement of how fast the atoms or molecules are moving.

Question 3

Heat Transfer

Answer 3

is energy from one object to another due to a difference in temperature

Question 4

Fahrenheit

Answer 4

is the scale of temperature, the freezing point of water is 32 degrees, and the boiling point is 212 degrees.

Question 5

Celsius

Answer 5

is the melting point of pure water at sea level (normal pressure). 100° Celsius is the boiling point of water at normal pressure.

Question 6

Kelvin

Answer 6

is a unit to measure temperature.

Question 7

Conduction

Answer 7

is when heat moves from one object to another object through direct touch.

Question 8

Convection

Answer 8

is a way in which heat travels. It occurs when heat is transferred by the movement of liquids or gases.

Question 9

Radiation

Answer 9

is the energy that moves from one place to another. Light, sound, heat, and X-rays are examples of radiation.

Question 10

Solid

Answer 10

a solid, the particles fit very closely together. They are repeatedly vibrating and twisting but they do not move past their neighbor particles because the particles are very close to each other.

Question 11

Liquid

Answer 11

s a form of matter. It is settled between solid and gas. Liquid has an almost-fixed volume, but no set shape. Every small force makes a liquid change its shape by flowing. Because of that, gravity makes liquids always take the shape of the contain

Question 12

Gas

Answer 12

is an air-like substance that can move around freely or they might flow to fit a container. … If they get out a container they spread very easily. Gases are all around us in the air that we breathe.

Question 13

Conductor

Answer 13

is substances that an electric charge can pass through without difficulty. An electric charge cannot pass through an insulator easily. Different types of atoms make a substance a conductor or an insulator. … Each atom is made of particles called electrons orbiting around a central nucleus.

Question 14

Insulator

Answer 14

is any material that keeps energy such as electricity, heat, or cold from easily transferring through is an insulator. Wood, plastic, rubber, and glass are good insulators.

Question 15

Conservation of Energy

Answer 15

is the amount of energy in a system never changes. No new energy is created, and no old energy is destroyed.

Question 16

State (of Matter)

Answer 16

Solids, liquids, and gases are different states of matter that have different physical properties.
