What is an expression of Dalton's law k constant?
Dalton's law of partial pressures states that in a mixture of gases, the partial pressure of each is the same as that gas would exert if it were alone in the same volume.
What does the proportionality constant k in coulombs law is huge in ordinary units whereas the proportionality constant g in newtons law of gravition is tiny mean?
It means that the force of electrical attraction (or repulsion) between two particles with units charges will be greater than the gravitational attraction between two particles with unit mass which are the same distance apart.
What is ideal gas constant r?
It is the value of the constant which appears in an equation relating the volume, temperature and pressure of an ideal gas. Its value is 8.314 4621 Joules/(Mol K).
Why you use k as constant in proportional values?
Any letter of the alphabet - or indeed other alphabets - can be used. The letters c and k are the more common symbols because they represent the phonetic start of "constant".Variables are often represented by the initial letter of the variable: v for velocity, t for time, m for mass and so on, or by letters at either end of the alphabet: a, b, c or x, y, z. Clearly, it can be confusing to use any of these as the constant of proportionality. So, through convention, k was selected as the default symbol.
What is 0.521 as a percentage?
To convert a decimal to a percentage, you multiply by 100. So, 0.521 multiplied by 100 is 52.1%. Therefore, 0.521 as a percentage is 52.1%.
