Answer:
Absolute zero is the lowest limit of the thermodynamic temperature scale, a state at which the enthalpy and entropy of a cooled ideal gas reach their minimum value, taken as zero kelvin.
No chemical because, its changeing the stuff
Answer:
Magnetism is believed to be caused by the alignment of small, numerous sub-units called : <em><u>Domains</u></em>
<em><u></u></em>
Explanation:
Domains : A magnetic domain is the region in which in which magnetic field of the atoms are grouped together and aligned.
- In unmagnetized material all the magnetic Domains point in different direction.
- In magnetised material (ferromagnets , antiferromagnets) , The Domains point in a particular( fixed Pattern) direction.
Answer:
6.02×10^23 atoms
Explanation:
Avogadros constant is a number that states the amount of atoms in one mole of a substance which is 6.02×10^23 to 3 significant figures.
The ice will float on the lake
<h3>Further explanation</h3>
Given
Mass of ice 57 g and a volume of 62 cm³
Required
Density
Solution
Density formula:
Input the value :
ρ = 57 g : 62 cm³
ρ = 0.919 g/cm³
Because the density of ice is less than water, it will float on the lake
.
