Is absolute dating better than relative? In relative dating, fossils are dated according to the depth at which they were buried. While in the absolute dating, isotopes of carbon are used for dating fossils. The absolute dating is more precise than relative dating because it tells the exact age of the fossils. What is the […]

Does Vantablack absorb heat?
Does Vantablack absorb heat? Vantablack converts light energy over a wide spectral range into heat energy, making it the blackest substance known (99.965% absorption of incident radiation). How much does Vantablack heat up? Vantablack absorbs up to 99.965% of visible light and can be created at 400 °C (752 °F). Can Vantablack boil water? Fun […]
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 […]
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, […]
What are 2 examples of gametes?
What are 2 examples of gametes? Examples of Gametes. The two most common gametes are sperm and ova. These two haploid cells can undergo internal or external fertilization and can differ from each other in size, form, and function. Some species produce both sperm and ova within the same organism. What are 3 types of […]
What is the relationship between metallic and ionization energy?
What is the relationship between metallic and ionization energy? Metallic character refers to the level of reactivity of a metal. The metallic character increases as you go down a group. Since the ionization energy decreases going down a group (or increases going up a group), the increased ability for metals lower in a group to […]
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. Do laundry rooms need vented doors? Most Dryer manufacturers will mandate a certain […]
