What are the conditions of one dimensional system?
What are the conditions of one dimensional system? Hence, in a one-dimensional system, temperature gradients exist along a single coordinate direction, and heat transfer occurs exclusively in that direction. The system is characterized by steady state conditions if the temperature at each point is independent of time. What is a one dimensional system? A one-dimensional […]
What is Brownian motion name two factors affecting it?
What is Brownian motion name two factors affecting it? Any factor that affects the movement of particles in a fluid impacts the rate of Brownian motion. For example, increased temperature, increased number of particles, small particle size, and low viscosity increase the rate of motion. What is Brownian motion easy? : a random movement of […]
Why is water wet?
Why is water wet? Water is wet because when you have water on your clothes or skin it evaporates into the surrounding air. Evaporation produces cooling because it’s like energy. Can I drown a fish? Fish are physically incapable of drowning because they have gills, not lungs. They can die if there’s not enough dissolved […]
What increases water supply?
What increases water supply? Dams and reservoirs Rivers transport water to the sea. Dams block rivers so that reservoirs of water build up behind, rather than drain away. This provides large supplies of drinking water all year round and reduces water insecurity , especially where precipitation may be seasonal. What is the difference between water […]
Is there friction in vacuum?
Is there friction in vacuum? The results seemed to go against the laws of physics: The vacuum, by definition, is completely empty space and does not exert friction on objects within it. As a decaying atom moves through the vacuum, it really does experience some kind of force resembling friction. Is there friction on the […]
What happens if you drink liquid helium?
What happens if you drink liquid helium? Although helium is nontoxic and inert, it can act as a simple asphyxiant by displacing the oxygen in air to levels below that required to support life. Inhalation of helium in excessive amounts can cause dizziness, nausea, vomiting, loss of consciousness and death. What is colder than liquid […]
Is calcium more reactive than magnesium?
Is calcium more reactive than magnesium? These metals are less reactive than the neighboring alkali metal. Magnesium is less active than sodium; calcium is less active than potassium; and so on. These metals become more active as we go down the column. Magnesium is more active than beryllium; calcium is more active than magnesium; and […]
What is the effect of temperature on rubber?
What is the effect of temperature on rubber? The rubber band actually expands when it gets colder! This seems counterintuitive because most materials expand when they are heated and contract when they get cold. This occurs because of the unusual polymer structure of rubber. How long does it take for rubber bands to decompose? 1 […]
Why are metals so hard?
Why are metals so hard? Metal have lots of free electrons which create a huge electron pressure (on the order of 100,000 atm), so to crush them,pressures higher than their internal electron gas pressure is required; this is why they are hard. Do metals have a giant structure? Metals consist of a giant metallic structure. […]
