Sour milk?

Question

You have two cartons of milk (the same size carton). One is nearly empty, the other is only half full. They both have exactly the same use-by date and are being kept in exactly the same conditions. The milk in which carton goes off first ...?

Answer 1

the smaller caton
acidity %age will increase quicker 1mg in 10ml is higher than 1mg in 75ml.
although microbial growth will be same (2X every20min). microbes will release lactic acid that will make milk sour

Answer 2

I disagree, I think the carton with the least in will turn quicker. This is because there is simply a smaller volume, in which the bacteria and therefore, toxins, can thrive. In the half full carton, the toxins will be equally distributed through the liquid, and therefore it would take longer to have any effect.

Answer 3

The nearly empty one due to there being more space in the carton and this will let more air in, turning the milk off

Answer 4

You'll need to qualify what 'nearly empty' and 'half full' are. You could be talking about the same amount of milk in which case they would both go off at the same time.

Answer 5

at the same time, because the surface of the milk is the same size - you'll notice it quicker with the almost empty one though, since there's less milk to sour. ;)

Answer 6

At the same time , since the conditions are the same

Answer 7

It is without a doubt the one you pour a glass of milk from. One of Murphy's laws I am certain.

Answer 8

neither they are the same so degrade at the same time and rate.
ta da...

Answer 9
