Are 2s and 2p degenerate? The 2s and 2p orbitals have the same energy for hydrogen. They are said to be degenerate energy levels, all the same. When the electron is held in the 1s orbital, it is said to be in its ground state, its lowest energy state. When the electron is a higher […]

What is its effect to the environment? Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. Can humans improve their environment if so how? Avoid Taking Cars or Carpool When Possible. Cars are harmful […]

Why do we need to follow Seat Belts Use Act? Seat belts reduce serious crash-related injuries and deaths by about half, according to the National Highway Traffic Safety Administration. The simple act of wearing a seat belt is the single most effective way to reduce the risk of fatality in a crash. Why are seat […]

Does the Fermi level depend on temperature? The experiment shows that the Fermi level decreases with increasing temperature and has almost the same temperature dependence as the energy gap. It is pinned at about 0.63 of energy gap below the conduction band. How is Fermi level calculated? You can use our Fermi level calculator to […]

What were two major shortcomings of Mendeleev periodic table? State two limitations of Mendeleev Periodic Table Elements with large differences in properties were included in the same group. No proper position could be given to the element hydrogen. The increasing order of atomic mass was not strictly followed throughout. How were the drawbacks removed in […]

What are the 3 equations for power? Ohm’s law equation (formula): V = I × R and the power law equation (formula): P = I × V. P = power, I or J = Latin: influare, international ampere, or intensity and R = resistance. V = voltage, electric potential difference Δ V or E = […]

Is it harder to kick a deflated football? “Basically, a little bit of air removed from the ball makes it easier to kick accurately because you get more ball surface in contact with the toe,” Timothy Gay, physics professor at the University of Nebraska, told NBC News. Why does cold air make balls deflate? As […]
