Answer:
E. There is not enough information to find the final temperature.
Explanation:
We do not the actual masses of ice and water involved in the question, so we cannot determine if the water freezes or the ice melts. So, there is not enough information to find the final temperature.
Answer:
0.34 x 10^-3 m^3
Explanation:
P1 = 6 x 10^5 N/m^2
T1 = 10 degree C = 10 + 273 = 283 K
T2 = 35 degree c = 35 + 273 = 308 K
Pressure remains constant , P2 = P1
P1 V1 = R T1
V1 = (8.314 x 283) / (6 x 10^5) = 3.92 x 10^-3 m^3
Now, let the Volume is V2
P1 V2 = R T2
V2 = (8.314 x 308) / (6 x 10^5) = 4.26 x 10^-3 m^3
Change in volume, v = V2 - V1 = (4.26 - 3.92) x 10^-3 = 0.34 x 10^-3 m^3
Answer:
D. move up to another shell that would form
Explanation:
An atom has protons, neutrons and electrons. Protons and neutrons are present in the nucleus and electrons orbit the nucleus in fixed shells. An electron can jump to higher shell when it gains energy and lower one when it loses energy. Thus, when single electron in hydrogen atom is given a small amount of energy, it would jump to another higher shell.

Explanation:
The process you're fishing for is "polarization", but that's a
misleading description.
Polarization doesn't do anything to change the light waves.
It simply filters out (absorbs, as with a polarizing filter) the
light waves that aren't vibrating in the desired plane, and
allows only those that are to pass.
The intensity of a light beam is always reduced after
polarizing it, because much (most) of the original light
has been removed.
A laser light source may be thought of as an exception,
since everything coming out of the laser is polarized.
