When investigating the effect of temperature on the rate of respiration, why do you need tube Q with glass beads?
To make sure it is a fair test - the volume of glass beads needs to be the same as the volume of soda lime
It is a control variable - it allows you to see what happens without the soda lime
It is a control - changes in temperature could also cause the bubble to move and this allows you to take that into account
Glass beads have a high specific heat capacity so it makes it easier to maintain a constant temperature in the tubes
Answer explanation
Hmm, I hope this one made you think outside the box a little!
