Is it safe to drink deuterium?

Is it safe to drink deuterium? The breakthrough involves the use of heavy water as a chemical tracer. Made by swapping water’s hydrogen atoms with their heavier relative, deuterium, heavy water looks and tastes like regular water and in small doses (no more than five tablespoons for humans) is safe to drink. How much of […]

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 […]

Does every room need a vent?

Does every room need a vent? Today, it is recommended to have one or multiple air vents in each room of your home or business to optimize air flow and reduce the cost of energy spent on cooling your home or office.

Why is rose quartz so powerful? “As a necklace, rose quartz is especially powerful because it’s worn close to the heart and heart chakra. This enables the heart center to open and release any tensions or stresses held there,” Birch claims. How long does it take to form rose quartz? Mine were formed in about […]

What is the most dangerous penguin?

What is the most dangerous penguin? Adélie Do penguins think humans are penguins? Penguins have no special fear of humans and will often approach groups of people. This is probably because penguins have no land predators in Antarctica or the nearby offshore islands. Instead, adult penguins are at risk at sea from predators such as […]

What factors affect London forces?

What factors affect London forces? The strength of London dispersion forces depends on the size of the molecule or atom. Larger atoms and molecules have more electrons. This leads to larger dipoles being established. London dispersion forces increase the larger the atomic size. What is the relationship between surface area and London dispersion forces? London […]

How can you identify a metal?

How can you identify a metal? Take your piece of metal and test its magnetization by sticking a magnet to it. If your metal sticks to the magnet, the metal could be cast iron or steel. If the metal does not stick to the magnet, your metal could be copper, brass, solver or aluminum. Which […]

Is there no friction on ice?

Is there no friction on ice? When a skate moves over the surface of ice, the friction between the skate and the ice generates heat that melts the outermost layer of ice. But ice is still slippery even when you’re standing still. If you stand on ice without moving, no friction exists to generate heat, […]
