Answer:
The correct answer to the following question will be "Particles".
Explanation:
- A particle seems to be a little component of something, it's little. When you're talking about a subatomic particle, that would be a structured user likely won't see because it's quite unbelievably thin, but it has a tiny mass as well as structural integrity. Such particles seem to be tinier than that of the particles or atoms.
- Such that the light which shines on the bit of metal could dissipate electrons, the particles seem to be more compatible with the light.
very cold temperatures
Explanation:
A superconductor performs best at very cold temperatures.
A superconductor is a perfect conductor that is able to allow the passage of electricity and heat without resistance.
- In superconductors, under certain conditions, resistance ceases to exist.
- Examples are aluminium, niobium e.t.c
- A conductor allows heat and current to pass through but with little resistance.

The number of atoms that are in 0.32 g of copper are
3.01 x10^21 atoms
<u><em>calculation</em></u>
<u><em> </em></u>Step 1: find the number of moles of Copper
moles = mass/molar mass
= 0.32 g /63.5 g/mol=0.005 moles
Step 2: use the Avogadro's constant to determine the number of atom
in 0.005 moles of Cu
that is according to Avogadro's law 1 mole =6.02 x10^23 atoms
0.005 moles=? atoms
by cross multiplication
= (0.005 moles x 6.02 x10^23 atoms) / 1 mole= 3.01 x10 ^21 atoms
