A scatter graph.
A line graph because time is a continuous variable
spread sheet
A scatter graph with one variable plotted along the x-axis and the other along the other axis.
The best graph for minutes would probably be a line or bar graph to measure something over time. Your welcome!

It is a histogram.

You're generally going to put the independent variable on the horizontal axis, ie the variable that you decided to change in the experiment. If it is a continuous variable (ie a run of numbers) then you will be plotting a line graph and joining with a line or curve of best fit. If your variable is categoric ie has labels rather than numbers, or if it is whole-number only, then you're going to be plotting a bar graph.
It can be, but not necessarily. If I had the heights (continuous variable) of a class of students I might use a histogram. Conversely, if I had the number of cars (discrete variable) driving by every minute, I would use a line graph. It all depends on which kind of graph conveys the information to your audience in the best way.
A graph going down from GAS to SOLID best represents a change in phase from a gas to a solid.
A value of the variable when the polynomial has a value of 0. Equivalently, the value of the variable when the graph of the polynomial intersects the variable axis (usually the x-axis).
Scatter graph i think. Hope that helps!
