More the number of turns, more will be the magnetic field produced.
Hence wire A will have magnetic field greater than wire B.
Hope this helps!
Answer:
24 atoms of H or 1.4 x 10²⁵ hydrogen atoms
Explanation:
simple method
1 H₂O has atoms of hydrogen and 1 atom of oxygen
while 12H₂O will have 24 atoms of hydrogen and 12 atom of oxygen
by Avagadros number
molar mass of water H₂0=18.01528 g/mol
1 mole of H₂0 have 2 moles of Hydrogen
one mole of water= 6.02⋅10²³water molecules =1.2 x 10²⁴hydrogen atoms
12 mole of H₂O = 1.2 x 10²⁴ x 12= 1.4 x 10²⁵ hydrogen atoms
<u />
1.4 x 10²⁵ hydrogen atoms in 12 moles of H₂O
<u />
thermal contact
When heat flows from one object or substance to another it is in contact with, the objects or substances are said to be in thermal contact. The state where objects in thermal contact with each other reach the same temperature, no heat flows between them.
