The difference between these two atoms is in the number of neutrons, and this coincides with the definition of isotopy.

Nitrogen 14 (14N) is the isotope of nitrogen whose nucleus consists of 7 protons and 7 neutrons. It is one of two stable isotopes of nitrogen, and accounts for 99.636% of the nitrogen present on Earth.

Nitrogen (15N) is the nitrogen isotope whose nucleus consists of 7 protons and 8 neutrons. It is the second of two stable isotopes of nitrogen, and represents 0.364% of the nitrogen present on Earth.

The number indicates the mass number of the atoms of the element. 15N, therefore, is heavier than 14N. Mass number is the total number of protons and neutrons in the nucleus of the atom. While 14N has 7 protons and 7 neutrons, 15N has 7 protons and 8 neutrons.

crimeas [40]

The population of rabbits on the volcanic island in big portion will dye out, some as a direct consequence from the volcanic eruption, and some because of the lack of food resources. Because the food will be much more scarce, the rabbits will become much smaller, thus needing less food, and also the reproduction process will be much slower and delayed, and as the island recovers from the eruption, the small remaining population of rabbits will start adapting on the new food sources. Once the rabbits are adapted to the new food resources their population will start rising again.

12 If pressure is applied to a rock until its volume is
mote1985 [20]

Answer: The correct answer to the question is option 2

If pressure is applied to a rock until it's volume is reduced by one half how the new density compares to it's original density is ; THE NEW DENSITY IS TWICE IT'S ORIGINAL DENSITY.

Explanation: Density is defined as mass divided by volume,density increases with pressure and it's determined by spaces between atoms in the object being measured.

Density is directly proportional to Pressure,so when pressure increases, Density increases and when pressure decreases,density decreases.

Density is indirectly or inversely proportional to temperature. so when pressure and density increases, temperature remains constant.

This is applicable to the scenerio with the rock in the question,as the pressure on the rock is increasing,the density is increasing too.
