What happens when water cools below 4? Right when the water freezes to ice, the ice becomes significantly less dense than the water and continues to float on the lake’s surface. Below 4° Celsius, water becomes less dense as it gets colder, causing water about to freeze to float to the top. What happens when […]
How do you solve accuracy and precision?
How do you solve accuracy and precision? Find the difference (subtract) between the accepted value and the experimental value, then divide by the accepted value. To determine if a value is precise find the average of your data, then subtract each measurement from it. This gives you a table of deviations. Then average the deviations. […]
What is the thermoelectric power?
What is the thermoelectric power? The conversion of thermal energy into electrical energy. Thermoelectric generation relies on a fuel source (e.g. fossil, nuclear, biomass, geothermal, or solar) to heat a fluid to drive a turbine. What is thermoelectric diagram? Thermo-electric Diagram. A diagram indicating the change in potential difference for a fixed difference of temperature […]
What 3 things affect the speed of sound?
What 3 things affect the speed of sound? Factors Affecting The Speed of Sound The Density of Medium: Sound requires a medium to travel. The density of the medium is among the factors which affect the speed of sound. The Temperature of The Medium: Higher the temperature, the higher is the speed of sound in […]
Does cold water help hurricanes?
Does cold water help hurricanes? Once they move over cold water or over land and lose touch with the hot water that powers them, these storms weaken and break apart. Recent studies have shown a link between ocean surface temperatures and tropical storm intensity – warmer waters fuel more energetic storms. What weakens a hurricane? […]
