Frage 1
Frage
What are the 3 ways heat can be transferred?
Antworten
-
Insulation, conduction, radiation
-
Conduction, radiation, convection
-
Convection, conduction, irradiation
Frage 2
Frage
Materials that are poor conductors of heat and that can sometimes block heat transfer are called insulators.
Frage 3
Frage
As air is [blank_start]heated[blank_end], its particles gain energy and move [blank_start]further[blank_end] apart, becoming [blank_start]less[blank_end] dense. This hot air is less dense than cool air and so it is pushed [blank_start]upwards[blank_end] by the cooler air around it.
Antworten
-
less
-
heated
-
further
-
upwards
Frage 4
Frage
Mark the correct boxes that show examples of conduction.
Antworten
-
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
Frage 5
Frage
Substances that transfer heat easily are known as conductors.
Frage 6

Convection currents occur in
Frage 7
Frage
Radiation transmits heat as [blank_start]invisible[blank_end] waves that travel at the speed of [blank_start]light[blank_end]. Heat travels through empty space between the Earth and the Sun. Heat from the sun cannot be transferred by [blank_start]conduction[blank_end] or convection because there are no [blank_start]particles[blank_end] to vibrate or flow in the vacuum of space.

Frage 8
Frage
What happens to heat energy when it hits a surface?
Antworten
-
reflected, absorbed and transmitted
-
reflected, rebounded and absorbed
-
rebounded, transmitted and infiltrated
Frage 9
Frage
[blank_start]Dark[blank_end] coloured objects heat up more [blank_start]quickly[blank_end] in sunlight than lighter coloured objects. This is because they are good [blank_start]absorbers[blank_end] of radiation, whereas lighter objects [blank_start]reflect[blank_end] most of the heat and don't heat up as quickly.
Antworten
-
Dark
-
quickly
-
absorbers
-
reflect
