Why is it easier for humans to walk through air than liquid water? It is easier to push an object through air than through water. This is because air is less dense than water. Since air is less dense this means there is less matter, or less “stuff”, in a certain area of air than […]
Can a translation undo a reflection?
Can a translation undo a reflection? No. The translation followed by a reflection would put a figure in a different location in the plane when compared to the same reflection followed by the same translation. Summarize, or have students summarize, the lesson. We can sequence rigid motions. What does translation do to an image? Translation […]
Why do cheetahs have very little genetic variation?
Why do cheetahs have very little genetic variation? Even though the number of cheetahs grew to as many as 100,000 during the 19th century, their genetic variability remained low due to the extreme bottleneck event that took place thousands of years previously. What are the two types of variation? There are two forms of variation: […]
Is pigment ink better for heat transfers?
Can aluminum be magnetized?
Can aluminum be magnetized? In our everyday experience aluminum doesn’t stick to magnets (neither does copper). Most matter will exhibit some magnetic attraction when under high enough magnetic fields. But under normal circumstances aluminum isn’t visibly magnetic. Why is stainless steel jewelry so cheap? Stainless steel not only mimics the look of fine, precious metal, […]
Which WiFi frequency is best?
Which WiFi frequency is best? Ideally, you should use the 2.4GHz band to connect devices for low bandwidth activities like browsing the Internet.

What gases are least ideal?
What gases are least ideal? 1 Answer. Sulfur dioxide should be the least volatile, have the greatest intermolecular interaction, and thus its behaviour is LEAST like the ideal. What is the difference between ideal gas and non ideal gas? Real gas and Ideal gas. As the particle size of an ideal gas is extremely small […]
What is average distance?
What is average distance? The average distance is the average shortest path of a graph, corresponding to the summa of all shortest paths between vertex couples divided for the total number of vertex couples. In quantitative terms, “high” and “low” are better defined when compared to the total number of nodes in the graph. How […]
What are the factors affecting the solubility?
What are the factors affecting the solubility? Solubility is the maximum amount of a substance that will dissolve in a given amount of solvent at a specific temperature. There are two direct factors that affect solubility: temperature and pressure. Temperature affects the solubility of both solids and gases, but pressure only affects the solubility of […]
Why are Fraunhofer lines missing?
Why are Fraunhofer lines missing? Fraunhofer lines are dark absorption lines in the solar spectrum that can be seen when sunlight is passed through a prism to separate it into the colors of the rainbow. These dark lines were segments of colors missing from the complete spectrum. … Can you touch dry ice? Dry Ice […]
