[T.h.o.m.a.s.]

dat koelertje zal net iets meer ml's mengsel bevatten dan een slangetje alleen als dat allemaal vol zit heb je net wat meer bij

A given volume of methanol expands about .12% for each degree (Celsius) of temperature increase. If one put 500 liters of methanol in a tank designed to maximize heat transfer with the surrounding air and the temperature rose 20 degrees, the volume would increase by 12 liters
Methanol expands much more than any common metal (aluminum expands roughly .0075% per volume per degree Celsius or .0025% per linear unit), and although some liquids (acetone, methyl ethyl keytone) have a somewhat higher coefficient of expansion methanol is relatively inexpensive and safe to handle--and unlike water one doesn't run the risk of damage during freezing weather.
