Answer:
There is one scientific method
it starts with an
OBSERVATION
then a HYPOTHESIS
which goes to planning, creating an EXPERIMENT
and finally a conclusion for your results
Explanation:
Answer:
Solid will sublime into a gas.
Explanation:
Triple point is a temperature where the three states of a substance coexist.
If the pressure is lower than the triple point, the substance does not exist as a liquid, so it is impossible that solid melts, or that the solid remains as a solid.
Liquid state is not stable.
Answer: -Water molecules surround solute molecules.
Explanation: The solubility of substances is governed by: Like dissolves like, which states that polar compounds are soluble in polar solvents and non polar compounds are soluble in non polar solvents.
Water being a polar solvent is able to dissolve only polar solutes and not able to dissolve non polar solutes.
The polar solutes when dissolved in water are surrounded by water molecules and due to high dielectric constant of water the polar molecules are separated and thus get dissolved in water.
<span>The heating of the metal would result in an energy expenditure
</span>that would make mining copper counterproductive
<span>The expenditure of the process is comparative
to how much material (rock, dirt, whatever) you have to process. The more will
be the material to be route, the larger will be the equipment, or the longer you have
to run it, and the more power and other other materials you need. so that is why its expensive to extract copper from contaminated lan</span>
