Potential energy is turned in to kinetic and kinetic I believe is being used in motion. potential means stored kentic means energy of movement.

From coefficients in the equation, for each mole of propane combusted, three moles of carbon dioxide molecules are produced. Thus
![n(CO_2) = 3 \; n(C_3H_8)](https://tex.z-dn.net/?f=%20n%28CO_2%29%20%3D%203%20%5C%3B%20n%28C_3H_8%29%20)
The question implied that the temperature and pressure on both carbon dioxide
and propane are those under room conditions- so these values are supposed to be interchangeable; thus by the ideal gas equation
![V(CO_2) = \frac{P \cdot V}{n(CO_2) \cdot R \cdot T} = \frac{P \cdot V}{3 \; n(C_3H_8) \cdot R \cdot T} = 3 \; V(C_3H_8) = 3 \cdot 4 \; cm^3 = 12 \; cm^3](https://tex.z-dn.net/?f=%20V%28CO_2%29%20%3D%20%5Cfrac%7BP%20%5Ccdot%20V%7D%7Bn%28CO_2%29%20%5Ccdot%20R%20%5Ccdot%20T%7D%20%3D%20%20%5Cfrac%7BP%20%5Ccdot%20V%7D%7B3%20%5C%3B%20n%28C_3H_8%29%20%5Ccdot%20R%20%5Ccdot%20T%7D%20%3D%203%20%5C%3B%20V%28C_3H_8%29%20%3D%203%20%5Ccdot%204%20%5C%3B%20cm%5E3%20%3D%2012%20%5C%3B%20cm%5E3%20)
Answer:
Explanation:
However, the model was misleading in several ways and ultimately destined for failure. The maturing field of quantum mechanics revealed that it was impossible to know an electron's position and velocity simultaneously. Bohr's well-defined orbits were replaced with probability “clouds” where an electron is likely to be.
