Which Cannot be separated physically? What is a Pure Substance? It is something which cannot be divided into parts by physical means, as it’s all made up of the same thing. Pure substances are either elements or compounds. Elements can NOT be separated into other types of matter (physically or chemically). What are the examples […]
How do you calculate water current?
How do you calculate water current? To calculate the water flow (in m3/s) multiply the average water velocity by the average cross-section. To express this water flow in litres per second (l/s), multiply the result (in m3/s) by 1000. 0.486 m3/s x 1 000 = 486 l/s. What is the speed in still water? Still […]
What are the basic components of a simple circuit?
What are the basic components of a simple circuit? A circuit is the path that an electric current travels on, and a simple circuit contains three components necessary to have a functioning electric circuit, namely, a source of voltage, a conductive path, and a resistor. What is the definition of a simple circuit? A simple […]
Does the buoyant force on a floating object depend on the weight?
Does the buoyant force on a floating object depend on the weight? The buoyant force depends on the mass of the object. The buoyant force depends on the weight of the object. The buoyant force is independent of the density of the liquid. The buoyant force depends on the volume of the liquid displaced. What […]

How do you interpret a chi square test?
How do you interpret a chi square test? For a Chi-square test, a p-value that is less than or equal to your significance level indicates there is sufficient evidence to conclude that the observed distribution is not the same as the expected distribution. You can conclude that a relationship exists between the categorical variables. What […]
Which state of matter has the greatest amount of molecular motion?
Which state of matter has the greatest amount of molecular motion? gas What has the greatest molecular motion? They are in constant motion and also different from molecules such as liquid molecules have more freedom of movement compared to solid molecules. At the same time they show less movement compared to gaseous molecules. In other […]

What gases are released when wood burns?
What gases are released when wood burns? When wood is burned, the combustion reaction produces heat and emissions in the form of water, organic vapors, gases, and particulates. The emissions of most concern are carbon monoxide (CO), carbon dioxide (CO2), sulfur oxides (SOx), and nitrogen oxides (NOx). Does burning wood cause global warming? Scientists estimate […]
