Heat Transfer

Frage 1 von 11

1

What are the 3 ways heat can be transferred?

Wähle eine der folgenden:

  • Insulation, conduction, radiation

  • Conduction, radiation, convection

  • Convection, conduction, irradiation

Erklärung

Frage 2 von 11

1

Materials that are poor conductors of heat and that can sometimes block heat transfer are called insulators.

Wähle eins der folgenden:

  • WAHR
  • FALSCH

Erklärung

As air is , its particles gain energy and move apart, becoming dense. This hot air is less dense than cool air and so it is pushed by the cooler air around it.

Erklärung

Frage 4 von 11

1

Mark the correct boxes that show examples of conduction.

Wähle eine oder mehr der folgenden:

  • Being warmed by an open fire

  • Heat flowing from a warm coffee cup to your hands

  • Water being heated in a saucepan

  • A saucepan getting hot on a stovetop

Erklärung

Frage 5 von 11

1

Substances that transfer heat easily are known as conductors.

Wähle eins der folgenden:

  • WAHR
  • FALSCH

Erklärung

Frage 6 von 11

1

Convection currents occur in

Wähle eine oder mehr der folgenden:

  • Solids

  • Liquids

  • Gases

Erklärung

1

Wähle von der Dropdown-Liste, um den Text zu vervollständigen.

Radiation transmits heat as ( invisible, light, radio ) waves that travel at the speed of ( light, sound, Lewis Hamilton's racecar, Winx ). Heat travels through empty space between the Earth and the Sun. Heat from the sun cannot be transferred by ( conduction, radiation, infiltration ) or convection because there are no ( particles, dust, snowflakes ) to vibrate or flow in the vacuum of space.

Erklärung

Frage 8 von 11

1

What happens to heat energy when it hits a surface?

Wähle eine der folgenden:

  • reflected, absorbed and transmitted

  • reflected, rebounded and absorbed

  • rebounded, transmitted and infiltrated

Erklärung

Fülle die Lücken, um den Text zu vervollständigen.

coloured objects heat up more in sunlight than lighter coloured objects. This is because they are good of radiation, whereas lighter objects most of the heat and don't heat up as quickly.

Erklärung

1

Temperature tells us how hot or cold something is.

Wähle eins der folgenden:

  • WAHR
  • FALSCH

Erklärung

Wähle eine der folgenden:

  • A form of energy that describes the energy of all particles in an object

  • a measure of the temperature of an object

  • hot and cold
