Answer:
Explanation:
Bose–Einstein condensate is what happens to a dilute gas when it is made very cold, near absolute zero ( −273.15 °C or −459.67 °F). It forms when the particles that make it up have very low energy. The gas has extremely low density, about one-hundred-thousandth the density of normal air.
I do hope I helped you, sir! :)
If you have 200. 0 g of radioisotope with a half-life of 5 days. 25g of isotope would remain after 15 days
Isotopes are members of an element family that have the same number of protons but differ in the number of neutrons. The atomic number of an element on the Periodic Table is determined by the number of protons in its nucleus. Carbon, for example, has six protons and has atomic number 6.
Radioisotopes are elemental radioactive isotopes. They can alternatively be defined as atoms with an unstable neutron-proton combination or surplus energy in their nucleus.
Radioisotopes are critical components of medical diagnostic techniques. They can be utilized for imaging to examine the dynamic processes taking place in various sections of the body when combined with imaging devices that register the gamma rays emitted from within.

Answer:
Variables and independent variables
Answer:
1 = strontium
2 = technetium
3 = silver
Explanation:
Strontium is present in 2 group of periodic table. It is alkaline earth metal. It is most reactive element and can not found free in nature. it is insoluble in water but react with water and form strontium hydroxide and hydrogen gas is also produced. It is radioactive element.
It is similar to the calcium and can incorporated into bones. The food rich with strontium is used to avoid the osteoporosis. It is found in leafy vegetables, grains, sea foods etc.
In given series strontium is highest in reactivity then technetium, while the technetium is more reactive than silver. The silver is less reactive as compared to both given elements.
Answer:
The physical states that are represented by each graph region are the liquid and the solid, the highest temperature is the liquid and as it freezes it becomes a solid. The particles change because when it's a liquid, it isn't that compact it's just spreading smootly but as it freezes the atoms start to stick together and become compact.
Explanation:
Hope that made sense!
