The main class of high-temperature superconductors are in the class of copper oxides (only some particular copper oxides) especially the Rare-earth barium copper oxides (REBCOs) such as Yttrium barium copper oxide (YBCO).
<h3>What superconducting material works with the highest temperature?</h3>
As of 2020, the material with the highest accepted superconducting temperature is an extremely pressurized carbonaceous sulfur hydride with a critical transition temperature of +15°C at 267 GPa.
<h3>How do high-temperature superconductors work?</h3>
High-temperature superconductivity, the ability of certain materials to conduct electricity with zero electrical resistance at temperatures above the boiling point of liquid nitrogen, was unexpectedly discovered in copper oxide (cuprate) materials in 1987.

Answer:
No
Explanation:
In my opinion water doesn't evaporates when is spills on a fabric or a shirt someone is wearing. The fabric or cloth whatever you may call it sucks the water, making you feel your shirt wet. But as the time passes it will slowly dry due to the sun or the warmth surrounding the area the fabric is at.
What mass of the following chemicals is needed to make the solutions indicated?
Answer:
271.6g
Explanation:
The mass of the chemicals need to make the needed solution can be derived by obtaining the number of moles first.
Given parameters:
Volume of solution = 1L
Molarity of HgCl₂ = 1M
number of moles of HgCl₂ = molarity of solution x volume
= 1 x 1
= 1 mole
From;
Mass of a substance = number of moles x molar mass;
we can find mass;
Molar mass of HgCl₂ = 200.6 + 2(35.5) = 271.6g/mol
Mass of the substance = 1 x 271.6 = 271.6g
Your answer is (4) 4, because the alpha particle is a helium nucleus (either an ion or an ejected particle from alpha decay), and it has a mass number of 4, being consisted of four nucleons, (2 protons and 2 neutrons).
