Does hot water have a higher entropy? The entropy increases whenever heat flows from a hot object to a cold object. It increases when ice melts, water is heated, water boils, water evaporates. The entropy increases when a gas flows from a container under high pressure into a region of lower pressure. Does cold or […]
Is riding a bike mechanical energy?
Is riding a bike mechanical energy? When you ride a bicycle, several things happen that require energy and it’s transformation. You pedaling the bike is transforming chemical energy, supplied by the breakdown of the food you eat, into mechanical energy to turn the pedals. The chemical energy is potential and the mechanical energy is kinetic. […]

What happens if you ice for more than 20 minutes?
What happens if you ice for more than 20 minutes? Greater than 20 minutes of icing can cause reactive vasodilation, or widening, of the vessels as the body tries to make sure the tissues get the blood supply they need. Studies have also shown 30 to 40 minutes in between icing sessions are needed to […]

How do you test if a solution is saturated?
How do you test if a solution is saturated? If more solute is added and it does not dissolve, then the original solution was saturated. If the added solute dissolves, then the original solution was unsaturated. A solution that has been allowed to reach equilibrium but which has extra undissolved solute at the bottom of […]
What solution did not dissolve?
What solution did not dissolve? A saturated solution at a given temperature is one that will not dissolve any more solute when the solution is in contact with solid solute. The solubility of a substance at a given temperature is the amount of it required to produce a saturated solution in a given amount of […]
How many 12v batteries can I connect in parallel?
How many 12v batteries can I connect in parallel? Technically, there’s no limit, but there is at least one caveat… No two batteries will have EXACTLY the same terminal voltages. That means, even for two batteries hardwired together, the slightly higher-voltage one will end up ‘charging’ the slightly lower voltage one. Does resistance affect battery […]
