A physical chemistry postgraduate entrance examination question
Thread Content
Three children bought a popsicle. Each of them ate a third of it and could only suck it. After the first child finished sucking, he said:: This popsicle is not very sweet. The second child said after finishing sucking: This popsicle is quite sweet. The third child said after finishing sucking: This popsicle is okay. ask: The ages of these three children. I heard this from my classmates. There is no answer. After thinking for a long time, I still found nothing.
I don’t have enough education and qualifications, I don’t know
According to your description, this question should test the phase diagram of the mixture. When the solid mixture melts, the time for sugar to precipitate is different, so the degree of sweetness is also different.
The second child is younger than the first and third children.
asked curiously: Is this a postgraduate entrance examination question for which school? It's ridiculous. You can test a person's specific age from this. So I think the poster made it up.
What's this? The first person left saliva on the popsicle, the second person ate saliva and popsicles, and the third person ate saliva
After thinking about it for a long time, I still have no answer. Is there something wrong with this question?
This question should test the phase diagram of the mixture, which requires the composition of the analyte!
I think we should examine the distribution of the two components after solidification of a homogeneous mixture of sugar and water!
You can recall how you ate popsicles when you were a child. The eating methods of different age groups should be different. If you suck hard enough, it will feel very sweet. If you suck hard enough, it will even feel a little bitter.
