Answer:
in an atom or molecule, no two electrons can have the same four electronic quantum numbers. As an orbital can contain a maximum of only two electrons, the two electrons must have opposing spins.
The two types of data are Qualitative and Quantitative data. Qualitative data is the data that cannot be quantified or measured where as quantitative data is quantified that is measured in terms of numbers.
The given statement 17 birds drink from the pond over the course of 2 hours describes the number of birds that drink water over a given amount time. So, it represents quantitative data. Hence the given statement that The following statement describes qualitative data: 17 birds drink from the pond over the course of 2 hours is false.
The answer is A, when these particles are heated they tend to speed up.
4. A good example would be heating a tin can of water using a Bunsen burner. Initially the flame produces radiation which heats the tin can. The tin can then transfers heat to the water through conduction. The hot water then rises to the top, in the convection process.
