Are you looking for the word "enthalpy"? It's defined as the heat content of a system. We can never know the actual enthalpy of a system, only measure changes in it.
Las leyes de los gases son un conjunto de leyes químicas y físicas que permiten determinar el comportamiento de los gases en un sistema cerrado.
Parámetros de las leyes de los gases

Answer:
ethane=c2h6
ethyne=c2h2
ethene=c2h6
Explanation:
ethane has single bond between carbon atoms(it is alkane.) ethyne has triple bond between carbon atoms(it is alkyne) ethene has double bond between carbon atoms (it is alkene)
Answer:
The longest wavelength is 2.19 × 10⁻⁷ m.
Explanation:
The work function (ф) is the minimum energy required to remove an electron from the surface of a metal. The minimum frequency required in a radiation to submit such energy can be calculated with the following expression.
ф = h × ν
where,
h is the Planck's constant (6.63 × 10⁻³⁴ J.s)
ν is the threshold frequency for the metal
In this case,
We can find the wavelength associated to this frequency using the following expression.
c = λ × ν
where,
c is the speed of light (3.00 × 10⁸ m/s)
λ is the wavelength
Then,
