A new foam product expands depending on the liquid temperature and time after mixing.
Its formula is given by V = where
V is the volume of the final expansion in litres
T is the time in minutes
F is the volume of foam liquid before curing in litres
The maximum temperature for this to work is 20 degrees Celsius.
At the maximum temperature, what is the volume if the foam liquid is 15 litres?
I know right! This is exactly how it was given in my practice test.
