Absolute zero is the temperature at which the motion of particles that constitute heat will be minimal. The answer is A. It is the lowest temperature that is theoretically possible. It is zero on the kelvin scale, but equivalent to -273.15°C. Hope i helped.

The correct answer is A. The temperature at which the motion of particles theoretically ceases.

Explanation:

The term "absolute zero" is used to refer to a temperature (degree of heat) in which particles have no movement or only minimal vibration as in this temperature the energy of particles is affected. Due to this, the absolute zero is one of the lowest temperatures that exists as it is equivalent to -273 °C or -459 °F, although it has been proved temperature can be even lower at certain circumstances. According to this, "absolute zero" is mainly defined by the lack of motion in particles and thus, the correct answer is "he temperature at which the motion of particles theoretically ceases".

Answer:

The increasing order of conductivity is O< Ge< Mn.

Explanation:

Electrical conductivity is defined as the measure of the ability of a material to conduct electrical current through it. The conductivity depends on the atomic and molecular structure of the material.

Metals are good conductors because they have a structure with many electrons with weak bonds, and this allows their movement instead non-metals have between four and eight valence electrons, which lack this tendency.

The conductivity increases in the periodic table from top to bottom and from right to left.

oxygen is a nonmetal therefore it is a bad conductor.

Germanium is a metalloid whose conductivity is greater than a nonmetal and worst than a metal.

Manganese is a metal,in this case, it is a good conductor.

Magnesium has three common isotopes.
sladkih [1.3K]

Answer:

Explanation:

percentage abundance of third isotope = 100 - ( 78.900 + 10.009)

= 11.091 %

Atomic mass

24.1687 x .789 + 25.4830 x .10009 + 24.305 x .11091  

19.069 + 2.5506 + 2.69566

= 24.3153 amu

Simple distillation is best used to separate two liquids that have boiling points that differ by
emmasim [6.3K]
The boiling points need to differ by 50 degrees to enable their complete separation ie of two different liquids. The separation occurs by first evaporation of one of the liquids and then its condensation and collection. It is a physical process not a chemical one.
