Is ice made of H2O? Ice is H2O. c. Water vapor is H2O Adam Sennet has no problem with this. Water is a liquid. Can you have water vapor at 0 C? Yes, water can stay liquid below zero degrees Celsius. There are a few ways in which this can happen. The freezing point of […]

Why is there no change in temperature during a phase change? The term change of phase means the same thing as the term change of state. i.e. during phase change, the energy supplied is used only to separate the molecules ; no part of it is used to increase the kinetic energy of the molecules. […]

How much energy is stored in spring? if you stretch a spring with k = 2, with a force of 4N, the extension will be 2m. the work done by us here is 4×2=8J. in other words, the energy transferred to the spring is 8J. but, the stored energy in the spring equals 1/2x2x2^2=4J (which […]

What liquids melt faster? On average, water melted in 145 minutes; sweet tea in 119 minutes; Coke in 118 minutes; PowerAde in 115 minutes and milk melted in 102 minutes. My results were that milk melted the fastest over-all out of all the liquids. Does water melt ice faster? Assuming the air and water are […]

Why do players use leather gloves when playing baseball?

Forensic toxicologists are frequently asked to determine the timing and extent of impairment resulting from different patterns of drug and alcohol use. What is the most common type […]

What is the drag coefficient of a f1 car? Typical Formula 1 car drag coefficients are between 0.7 and 1.1, depending on the circuit the car is set up for. ! A lot of this drag is due to the wings but a lot of it is due to the uncovered wheels. What car has […]

Are ionic structures strong? Ionic compounds have regular structures, called giant ionic lattices . In a giant ionic lattice, there are strong electrostatic forces of attraction acting in all directions between the oppositely charged ions. The structure and bonding of ionic compounds explain their properties . Why do giant ionic structures dissolve in water? To […]

How do you find the flux of a curved surface? The flux associated with the base of the hemisphere is ϕ=-EπR2 (negative as it is the incoming flux). Hence, the same amount of flux wil be associated with curved surface, but the sigh of the flux will be positive as it is as outgoing flux. […]

What is the benthic zone quizlet? Benthic Zone. The bottom region of oceans and bodies of fresh water. How deep is the abyssal zone? The Abyssopelagic Zone (or abyssal zone) extends from 13,100 feet (4,000 meters) to 19,700 feet (6,000 meters). It is the pitch-black bottom layer of the ocean. The name (abyss) comes from […]
