Answers
The mass of protons and neutrons are both 1 amu (atomic mass unit). The mass of the electron is 0.00054. Therefore, when determining the isotopes when given mass, you only focus on the neutrons as they are the subatomic particles that are significantly affecting the atomic mass.

A sandblasted rock should be much smoother, since the sand blasts away any rough edges. It will, however, be slightly smaller due to losing those edges.
A sandblasted rock differs from a non-sandblasted rock in various aspects, including a change in texture and color of the rock's surface.
Sandblasting is a process in which a high-pressure stream of sand or other abrasive material is used to remove material from the surface of an object.
The most noticeable difference between a sandblasted rock and one that hasn't been sandblasted is the texture of the surface. A sandblasted rock will typically have a rough, pitted surface, while an unsandblasted rock will have a smoother surface.
Sandblasting can also change the color of a rock. If the rock has a layer of surface material that is a different color than the underlying rock, sandblasting can remove the surface layer and expose the underlying rock.
Therefore, a sandblasted rock would differ from a rock that hasn't been sandblasted in several ways such as change in texture and color of a rock's surface, creating a rough, pitted texture and exposing the underlying rock.

Explanation:
Combine Gas law is a combination of three gas laws which are Boyle's Law, Charles' Law, and Gay-Lussac's Law.
Combine gas law states that the ratio of the product of pressure and volume and the absolute temperature of a gas is equal to a constant.
Hence the equation becomes:
where P = pressure,
V = volume,
T = absolute temperature,
k = constant.
Now we know that Kelvin = °Celsius + 273
For all gas law problems it is necessary to work in the Kelvin scale because temperature is in the denominator in the combined gas laws (P/T, V/T and PV/T) and can be derived in the ideal gas law to the denominator (PV/RT) . If we measured temperature in Celsius we could have a value of zero degrees Celsius and this would solve as no solution, as you cannot have zero in the denominator.
However, if we reached zero in the Kelvin scale this would be absolute zero and all matter would stop and therefore there would be no gas laws to worry about.
