what type of heat transfer is detected by a thermal imaging camera to produce this image

• conduction

• convection

• radiation

• all of them

Answer explanation

a thermal imaging camera absorbs infrared and produces an image. The colours in the image are 'false'. The camera works out which areas are hotter and shows them as more red in the image.

what is this image showing?

• conduction

• convection

• radiation

• all of the above

Answer explanation

Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy.

When this happens a convection current is set up
