Are temperature and moles directly proportional? At constant temperature and pressure the volume of a gas is directly proportional to the number of moles of gas. At constant temperature and volume the pressure of a gas is directly proportional to the number of moles of gas. What happens to pressure when volume and temperature decrease? […]

Is every 13th wave bigger? It is not true that every 13th wave is larger than the others, as claimed in the film. In fact, there exists no pattern in wave sizes. In the original Kon-Tiki documentary, it was shown that the crew simply waited for a wave big enough to carry them over the […]

What does current flow mean? Current flow basically means the flow of electric charges with respect to time. In an electric circuit, when the electric charge is flowing in one direction, the current will flow in the opposite direction. From Ohm’s law, the current can be defined as the voltage through the circuit per unit […]

What is the main distinction between primary and secondary source? Primary sources can be described as those sources that are closest to the origin of the information. Secondary sources often use generalizations, analysis, interpretation, and synthesis of primary sources. Examples of secondary sources include textbooks, articles, and reference books.

Is Pi a Radian? Radians are not measured in Pi, they are just a number. A radian is defined as the ratio between the length of a circular arc and the radius of the circle. For example if the arc goes around 360 degrees (a full circle), the radians are 2PiR divided by R. The […]

Is sweating positive or negative feedback? Another example of negative feedback occurs when your body’s temperature begins to rise and a negative feedback response works to counteract and stop the rise in temperature. Sweating is a good example of negative feedback. Is body temperature positive or negative feedback? (b) Body temperature is regulated by negative […]

Do lights in equal distance away from you have the same brightness? The intensity or brightness of light as a function of the distance from the light source follows an inverse square relationship. Notice that as the distance increases, the light must spread out over a larger surface and the surface brightness decreases in accordance […]
