<span>1) To form a solution </span>one substance must dissolve in another. 2) A salt is dissolved in water, which has a boiling point of 100°C. The boiling point of the solution will be <span>greater than 100°C. </span>3) During the formation of a solution, energy is <span>either released or absorbed. </span>4) <span>A student dissolved equal amounts of salt in equal amounts of warm water, room-temperature water, and ice water.</span>The salt dissolved most quickly in the warm water.
1.one substance must dissolve another : the solvent breaks the the solute causing it to dissociate into the solvent it can be both solids or gases that dissolve in the solute
2.the melting point will be higher than 100 degrees as the salt causes the solution to gain a higher melting point
3.either released or absorbed : energy is required to dissolve the solute but the solute may also release energy
4.the salt dissolved most quickly in the warm water : as there is more energy for the solute to dissolve
It is important to only test one variable at a time because you need to be able to disprove or prove a problem with just one independent variable. When you have several variables in the experiment, it would be impossible to know which variable honestly caused the end result.
Since most of the data scientist collect is quantitative, data tables and charts are usually used to organize the information • Graphs are created from data tables • hope that helps love!
