A 100 W light bulb is placed in a cylinder equipped with a moveable piston. The light bulb is turned on for 2.0×10−2 hour, and t
drek231 [11]

Answer:

(a) ΔU = 7.2x10²

(b) W = -5.1x10²

(c) q = 5.2x10²

Explanation:

From the definition of power (p), we have:

p = \frac {\Delta W}{\Delta t} = \frac {\Delta U}{\Delta t} (1)

<em>where, p: is power (J/s = W (watt)) W: is work = ΔU (J) and t: is time (s) </em>  

(a) We can calculate the energy (ΔU) using equation (1):

\Delta U = p \cdot \Delta t = 100 \frac{J}{s} \cdot 2.0\cdot 10^{-2} h \cdot \frac{3600s}{1h} = 7.2 \cdot 10^{2} J  

(b) The work is related to pressure and volume by:

\Delta W = -p \Delta V

<em>where p: pressure and ΔV: change in volume = V final - V initial      </em>

\Delta W = - p \cdot (V_{fin} - V_{ini}) = - 1.0 atm (5.88L - 0.85L) = - 5.03 L \cdot atm \cdot \frac{101.33J}{1 L\cdot atm} = -5.1 \cdot 10^{2} J

(c) By the definition of Energy, we can calculate q:

\Delta U = \Delta W + \Delta q

<em>where Δq: is the heat transfer </em>

\Delta q = \Delta U - \Delta W = 7.2 J - (-5.1 \cdot 10^{2} J) = 5.2 \cdot 10^{2} J    

I hope it helps you!

Why was einstein not happy with the probable positions of electrons in the orbitals?
Naddik [55]

Since electron orbitals are described as probability clouds, Einstein disagreement with the probable positions of electrons in the orbitals is that, It is not possible to know the orbit of an electron when the position is under probability.

According to Bohr's theory, it is difficult to locate electron or cannot be located in a definite region. Electron has to be found in an orbit and nowhere else. When the probability of finding an electron in a given spherical shell around the nucleus is plotted the distance of the electron from the nucleus for the hydrogen atom, the graph indicates that the probability of finding the electron increases as the distance between the electron and the nucleus decreases

Bohr claimed that electrons a entities had only probabilities if they weren't observed. While Einstein argued that they had independent reality.

But in wave mechanics Model, there is a slight chance of knowing the location of the electron.

Heisenberg uncertainty principle also claim the possibility of knowing the position of electron. Albert Einstein also claim that; to determine the position of an electron to an accurate extent, you would have to compromise your ability to know it's momentum. This inaccuracy will eventually affect the measurement of momentum which will be extremely uncertain.

Since electron orbitals are described as probability clouds, Einstein disagreement with the probable positions of electrons in the orbitals is that, It is not possible to know the orbit of an electron when the position is under probability.
