Answer:
a) a space in an atom where an electron is most likely to be found
Explanation:
Atomic orbital is the mathematical function which describes wave-like behavior of the electrons present in the atom.
It is used to calculate probability of finding the electron of the atom in any region around nucleus of the atom. Atomic orbital is the physical region or a three dimensional space where the probability of finding the electron is more than 90% which also means that the space where an electron is most likely to be found. They are boundless space and have definite energy.
Option A best describes atomic orbital.

The process of a gas to a liquid is called condensation
Avogadro's number tells you that in one mol of element (sulfur) there are 6.022x10^23 atoms...
So,
1 mol : 6.022x10^23 = x mol : 1.2x10^2
x = 1.99 x 10^-22 mol
*Although this should be correct, you might want to check your question again. You probably misinterpret the question... you want 1.2x10^23 !! :) check it.
Temperature of the same cup of water will rise by 6 °C unless it boils.
<h3>Explanation</h3>
.
However, neither 
nor 
is given.
Adding 
to this cup of water of mass rises its temperature by 
.
In other words,
.
Both and are constant for the same cup of water unless the water boils. It's possible to reuse the value of 
in the second calculation. Here's how:
