Answer:
When a low cost fuel is available, internal combustion drivers surpass all others in compactness and low cost of installation and operation. For example, gas compression on a large scale has long been done with integral engine compressors.
Answer:
If the container is cooled, the gas inside likewise gets colder and its pressure is observed to decrease.
Explanation:
Since the container is rigid and tightly sealed, both the volume and number of moles of gas remain constant. If we heat the sphere, the gas inside gets hotter and the pressure increases.
The minimum energy required to remove an electron from a potassium metal can be obtained by subtracting the energy of the incident photons from the kinetic energy of the removed photoelectrons. Based from the given values, the following equation is obtained:
Minimum energy required = 4.23×10^-19 J - <span>1.864×10^-21 J
</span>
We then get 4.2114 x 10^-19 J as the minimum energy required to remove the electron. We then convert this into units of energy per mole. This is to be done by using Avogadro's number which result to the following equation:
Minimum energy required per mole = 4.2114 x 10^-19 J x 6.022 x 10^23 mol^-1
The final answer is then 253.608 kJ/mol
