passing through it. In mechanics, the definition of power is the rate of doing work W. It's defined as W/t, where t is the time it takes for the work to be completed. To get the result in watts, work must be expressed in joules, and time must be ...
and the variable describes the frequency in s-1. planck’s law helps us calculate the energy of photons when their frequency is known. if the wavelength is known, you can calculate the energy using the wave equation to calculate the frequency and then apply planck’s equation to find the ...
Ea is the activation energy of the chemical reaction in Joules kB is the Boltzmann constant In both forms of the equation, the units of A are the same as those of the rate constant. The units vary according to the order of the reaction. In a first-order reaction, A has units of per...
With this calculator, you can simply determine what the specific heat capacity of a substance is without the need to calculate everything yourself. Let’s have a look at specific heat capacities of some common gases, liquids, and solids: ...
They reason that the ideal gas law (PV = nRT) can be used to calculate n, the number of moles of gas, provided they can determine P, V, and T. Knowing n, they can determine the mass of gas because they know that 1 mole of helium has a mass of 4 gm. The pressure gauge on ...
