the metal rod has a pin attached with wax.
Oliver measures the time it takes before the pin falls off the rod.
the pin takes 45 seconds before it falls.

a.) describe how Oliver makes hie result more reliable.



b.) oliver does a risk assessment for his investigation.

He considers the safety hazards.
Describe TWO of the safety hazards in Olivers investigation.

1.

2.​

Answer 1

He can make the experiment more reliable by repeating the experiments about three times and then taking the average value.

What is thermal conduction?

Conduction is a mode of heat transfer in which there is no actual movement of the particles of the substance. Oliver can make his results more reliable by accurately observing the time taken before the pin falls off and by repeating the experiments about three times and then taking the average value.

Also, he need to;

1. Avoid an outburst of flame.
2. Prevent the hot metal from touching his skin.
