Heat transfer S8P2D: understanding the ways in which heat can be transferred

Introduction

You will be learning about heat transfer and how it realtes to your everyday life. 

Task

read the following information. After you have completed the reading complete the questions in evaluation

  • radiation
  • induction
  • convection
  • conduction

A form of energy that can move from a hot place to a cooler place; the transfer of energy from one body to another.

  • Celsius
  • Fahrenheit
  • Freezing point
  • Heat

Which type of heat transfer is happening when the sun warms your face?

  • convection
  • conduction
  • radiation

What is the direct transfer of heat from one substance to another substance that is touching called?

  • radiation
  • convection
  • conduction
  • troposphere

What is convection?

  • Transfer of heat by the movement of currents within a fluid
  • Transfer of heat from one particle to another without the movement of matter
  • The transfer of energy by electromagnetic waves
  • A conductor
  • An insulator

Which of the following energy transfers would be correct?

  • Thermal energy from a hot drink is transferred to cold hands.
  • Thermal energy from the refrigerator is transferred to a hot pie in the refrigerator.
  • An ice cube loses thermal energy to a hot cup of tea as it melts.

Which of the following best explains why the end of a spoon sticking out of a cup of hot water also gets hot?

  • The hot water causes a chemical reaction to take place in the spoon.
  • The heat from the hot water is conducted to the spoon handle.
  • The hot water heats the air surrounding the upper part of the spoon.
  • The hot water causes a physical change in the spoon handle.

Circle the following materials that would make good conductors

  • Copper
  • Glass
  • Plastic
  • A sweatshirt
  • Gold
  • Wood
  • Rubber
  • Aluminum

Which transfers thermal energy better?

  1. A conductor
  2. An insulator

 Thermal Energy ALWAYS moves from COLD to HOT.

  1. True
  2. False

Which of the following is not a form of heat transfer?

  • conduction
  • convection
  • transpiration
  • radiation

The faster the particles of a gas are moving, the

  • lower their energy and the higher their temperature.
  • greater their energy and the lower their temperature
  • lower their energy and the lower their temperature.
  • greater their energy and the higher their temperature

Thermal energy is transferred from a                          object to a                          object.

  • cooler, warmer
  • colder, same temperature
  • same temperature, warmer
  • warmer, cooler

A measure of the average kinetic energy of the particles of a substance is its

  • temperature
  • pressure
  • force
  • volume

If Mr. Lovering burns his hand grabbing a hot cup of coffee, what type of thermal energy transfer has taken place?

  • Radiation
  • Convection
  • Conduction
  • Equilibrium

When energy is added to a liquid without changing its phase, the particles will...

  • move faster
  • be arranged more disorderly
  • move away from their fixed positions
  • move further apart
