What makes it look like stars are moving? There are actually two different reasons why stars appear to move across our sky. The first is because the Earth is spinning and second because the Earth itself is moving around the Sun. At the same time as the Earth is moving around the sun it is […]
Why is skim milk bad for you?
Why is skim milk bad for you? Skim can leave you feeling unsatisfied, which leads many people to fill up on less-healthy “non-fat” foods. This is because saturated fats like those found in whole milk trigger the release of the hormone cholecystokinin, which makes you feel full. 5. Skim milk has been linked with “transient” […]

Does ethanol have a high surface tension?
Does ethanol have a high surface tension? Ethyl alcohol has some hydrogen-bonding, but one side of it is a hydrocarbon ( CH bonds), so the hydrogen-bonding in the big picture is not nearly as prominent. Therefore, since water molecules on a liquid surface are harder to push down on the surface tension is higher for […]
What is the efficiency of a power cycle?
What is the efficiency of a power cycle? The gross thermal-to-electric efficiency of these cycles in currently operating power-tower plants is typically between 30% and 40% at turbine inlet temperatures <600°C. At higher input temperatures, the thermal-to-electric efficiency of the power cycles increases following Carnot’s theorem. What is the efficiency of Otto cycle? Variation of […]
