Classifying the methods of heat transfer

Multiple Choice

Everything in the universe can be classified as either ____.

• Energy or Matter

• Helpful or Harmful

• Good or Evil

Multiple Select

Some examples of energy are ____.

(Pick 3!)

• Heat

• Glasses

• Light

• Earth

• Sound

What is temperature?

• Temperature is a measure of how fast matter is moving.

• Solids have a low temperature because the matter moves slowly.

• Gases have a high temperature because the matter moves quickly.

• Scientists measure the temperature using a thermometer, and report their observations using degrees Celsius.

Multiple Choice

What tool is used to measure temperature?

• Thermometer

• Scale

• Meter Stick

• Stopwatch

Heat Transfer

• When two objects have different temperatures, energy will move from the hotter object to the colder object.

• The movement from energy from a hot object to a cold object is called heat transfer.

• Heat transfer will continue until the two objects have the same temperature.

Multiple Choice

You put a hot coffee cup in a cold room.

How will the heat transfer?

• From the cup to the room

• From the room to the cup

Multiple Choice

You leave the window open on a cold winter day.

How will the heat transfer?

• From the classroom to outside

• From outside to the classroom

Classifying Heat Transfer

• Remember that classify means to divide into groups.

• Conduction - heat transfer through solid objects

• Convection - heat transfer through liquids and gases

• Radiation - heat transfer through waves

• This classification lets scientists predict how temperatures will change.

Multiple Choice

Classify means ____.

• Put things together

• Divide things into groups

• Introduce to a school

• Make more fancy

Multiple Choice

To make it easier to study Heat Transfer, scientists classify the methods into

3 categories

Those categories are:

• Producers

  Consumers

  Decomposers

• Stop

  Drop

  Roll

• Helpful

  Harmful

  Neutral

• Conduction

  Convection

  Radiation

Multiple Choice

When scientists have classified all of the heat transfer in a system, they can ___.

• Predict how temperatures will change

• Take a break

• Control how temperatures will change

where ___."

Conductors vs Insulators

• Solids that speed up the transfer of heat are called "Conductors."

• Metal, diamond, and graphite are conductors.

• Conductors have tightly-packed particles, which make heat easy to transfer.

• Solids that slow down heat transfer are called "Insulators."

• Wood, plastic, and cloth are insulators.

• Insulators have loosely-packed particles, which make heat hard to transfer.
