So.... for 2 classes we did graphs by using the microsoft excel.
Graphs that were taken includes: Density of Water, Density of Hot water, Temperature Vs volume of gas and lastly Mass Vs Volume.
How to graph?
As an example, here's how to graph the Density of Water.
STEPS:
- open excel
- plug in all the numbers for volume(mL) and mass (g) { make sure its separated into 2 columns}
- highlight both column then click "chart"
- choose "scatter"
- lable: title, subtitle, trend line type ( highlight + click "show formula" to get the formula) , x and y value
- click "add decimal place ( or something)" if the # keeps rounding itself to 1 ( this refer to the last 2 graph that we did)
- NOW, you get to design your graph. BE creative. Do ANYTHING you want. Lol
Question: Which one has a higher density? Cold water or Hot water?
Answer: Cold water, because as you heat water its molecules gain kinetic energy and the water becomes much less denseVIDEO!
