Explanation:
its a chair that spins around
Answer:
Y = 3.87 x 10⁻³ m = 3.87 mm
Explanation:
This problem can be solved by using Young's double-slit experiment formula:
where,
Y = fringe spacing = ?
L = slit to screen distance = 2 m
λ = wavelength of light = 580 nm = 5.8 x 10⁻⁷ m
d = slit width = 0.3 mm = 3 x 10⁻⁴ m
Therefore,
<u>Y = 3.87 x 10⁻³ m = 3.87 mm</u>
When the pump removed the air in the bell, the balloon expanded.
<u>Option: B</u>
<u>Explanation:</u>
In order to construct our own environment in the glass jar known as bell jar system, which can be used to explore and consider our larger environment on Earths, for an instance. Here a glass jar that hinges on an airtight rubber basis i.e seals appropriately. At the top of the jar, a bung is connected to it which passed via a metal tube. It has an adjacent flexible tube that goes to a hand vacuum pump and the best hand-powered pump was made with a wine preserver.
When the pump extracts the air from the bell jar, the pressure inside the balloon naturally decreases. The balloon usually has a air pressure around it, which restricts its size, but when this air is extracted and the pressure around it decreases the gas in the balloon will expand and the balloon seems to be inflating. When you release the air back into the bell jar, it will once again compress back to its actual size.
Answer:
Because with Gibbs free energy we can determine the spuriousity of reaction occurrence
Explanation:
Gibbs energy: is a thermodynamic potential that has units of energy that gives the condition of equilibrium and spontaneity for a chemical reaction (at constant pressure and temperature).
In the chemical thermodynamics of reactions and in non-cyclic processes, there are four useful quantities called "thermodynamic potentials". These are internal energy, enthalpy, Helmholtz free energy and Gibbs free energy.
While Entropy is a thermodynamic function that is a measure of the unusable part of the energy contained in a system or matter. It serves to measure the degree of disorder within a process and allows us to distinguish useful energy, which is what becomes entirely work, of useless, which is lost in the environment.
