Convection is when heat from LIQUIDS and GASES is transferred from hot areas to cooler areas. • When liquids and gases are heated the particles become lighter and rise. If we take a look at my cup of tea, the steam you can see is a good example. As the steam rises from the tea it shows the heat transferring from the hot liquid and into the cooler air above it. • When a fire spreads through convection, the heated air rises and creates convection currents, which is when the hot air transfers into cooler air and heats it up. This process feeds the fire more oxygen and it continues to grow. • For more information about how fires spread and Fire Awareness, head over to our website - https://www.ihasco.co.uk/courses/deta...
