Answer:
When a solution is heated, the solvent evaporates, leaving behind the dissolved solids as residue. When a solution containing dissolved solutes is heated, the solvent will evaporate.
Explanation:
. P.S. Evaporation to dryness cannot be use for solutions like sugar solution because the sugar will decompose upon heating.
Answer:
Gas, has no shape but does take up volume
Answer:
New temperature T2 = 707.5 K (Approx.)
Explanation:
Given:
Old pressure P1 = 2 atm
Old temperature T1 = 283 K
New Pressure P2 = 5 atm
Find:
New temperature T2
Computation:
Using Gay-Lussac law;
P1 / T1 = P2 / T2
So,
2 / 283 = 5 / T2
New temperature T2 = 707.5 K (Approx.)
I believe it's the second option. 2 or more elements joined together such that the elements have lost their individual identity in favour of a new set of properties.
