Answer:
Kindly check explanation section.
[tectonic activity].
Explanation:
What the team of geologists were talking about is known as the continental drift. The term continental drift which was introduced in the 1500s by people like Abraham Ortelius was mot accepted because the reasons backing it were not sufficient enough. The work on Continental drift was also worked on by people like Charles Lyell, Alfred Russel and Wegener. The term continental shift is used by geologists and other scientists to explain the movement of continents over time. The movement of continents is actually the movement on tectonic plates.
Although the movement of continents has not been accepted generally in those times, there has been modern evidence to back it up such as the record on fossils found in in several continents which are similar.
Diego‘s little brother should be told that different continents move at different rate and the movement is on the tectonic plates.
At high temperature the gas would diffuse out as the pressure increases and at extremely low temperature the solid becomes compact.
Explanation:
The states of matter largely depends on the temperature. Any substance when crosses the threshold temperature its phase changes.
When temperature is low the motion of molecules is also low and internal energy also gets low. Solid have tendency of settling in low energy level and have highly compact molecules. At low temperature the solid would compress as molecules would be highly condensed.
Gas in the nature has its molecules quite far apart in matter. According to Kinetic theory of gases the increase in temperature causes rapid collisions of the gas molecule as the kinetic energy of molecules increases. The greater force of collision would cause increase in pressure of the container and increased diffusion rate.
I believe its Sodium Chloride.
I hope that helps!
Density is defined as " the ratio of mass of the substance to its volume ". i.e.
d = m/v ------------------------ (1)
volume of the steel sample is required, so putting mass of the steel sample and its density in equation (1),
8 = 80 / v
It implies that,
v = 80 / 8
v = 10 cm^3
Each isotope of Oxygen has a different number of neutrons
<h3>Further explanation
</h3>
The elements in nature have several types of isotopes
Atomic mass is the average atomic mass of all its isotopes
Isotopes are atoms has the same number of protons but has a different number of neutrons.
So Isotopes are elements that have the same Atomic Number (Proton)
Some of the isotopes of oxygen are:
Each isotope has 8 protons and 8 electrons but has a different number of neutrons
For O-16: number of neutrons = 16-8 = 8
For O-17: number of neutrons = 17-8 = 9
For O-18: number of neutrons = 18-8 = 10
