Oxygen uptake by living organisms
Absorbs CO2CO_2CO2 produced during respiration
Control - same mass as organisms
O2O_2O2 uptake reduces gas volume in tube
V=π×r2×dV = \pi \times r^2 \times dV=π×r2×d

Rate of respiration increases
Enzymes work more efficiently at higher temps
To control temperature
Insects, maggots, woodlice, germinating peas
Corrosive - causes skin burns
Volume of oxygen taken up
Use digital manometer for better precision
