When a substance changes from a solid to a liquid what is the name of the process?
- A.
Evaporation
- B.
Boiling.
- C.
Melting.
- D.
Sublimation.
Correct Answer
C. Melting.Explanation
When a substance changes from a solid to a liquid, the process is called melting. This occurs when the substance's temperature increases and reaches its melting point, causing the solid particles to gain enough energy to break their rigid structure and transition into a liquid state. Evaporation refers to the process of a liquid turning into a gas, boiling specifically refers to the rapid vaporization that occurs when a liquid reaches its boiling point, and sublimation is the process in which a solid directly turns into a gas without passing through the liquid state.Rate this question:

In fractional distillation crude oil is separated into the different compounds that it is made up from. To do this the compounds must be changed from liquids into gases. Which of the following will help change the liquids into gases?
- A.
By cooling the crude oil.
- B.
By keeping the crude oil at room temperature
- C.
By heating the crude oil.
- D.
By adding water to the crude oil.
Correct Answer
C. By heating the crude oil.Explanation
Heating the crude oil will help change the liquids into gases. This is because heating increases the temperature of the crude oil, causing the molecules to gain energy and move more rapidly. As a result, the intermolecular forces holding the liquid molecules together weaken, allowing them to escape into the gas phase. This process is known as vaporization or evaporation. By heating the crude oil, the different compounds can be separated based on their boiling points, as each compound will vaporize at a different temperature.Rate this question:

Which separation technique is most suitable for obtaining a dissolved solid from a solvent?
- A.
Chromatography.
- B.
Distillation
- C.
Crystallisation.
- D.
Filtration.
Correct Answer
C. Crystallisation.Explanation
Crystallisation is the most suitable separation technique for obtaining a dissolved solid from a solvent because it involves the formation of crystals from a supersaturated solution. By cooling or evaporating the solvent, the solute molecules come together and form solid crystals, which can then be separated from the remaining liquid. This method is particularly effective for substances with high solubility in a solvent and allows for the purification and isolation of the solid compound.Rate this question:

A soft drinks company have had many complaints about the drink they sell leaving sugar in the bottom of the glass when served with ice. When the drink is made in the factory, sugar is added until a saturated solution is formed at room temperature. What is the most likely explanation for the solid sugar appearing in the drink?
- A.
When heated the sugar solution becomes more dilute.
- B.
When cooled by the ice the solution cannot dissolve as much sugar and so a saturated solution is formed.
- C.
When cooled by the ice the liquid sugar condenses and turns back into solid sugar.
- D.
Different liquids have different melting and boiling points.
Correct Answer
B. When cooled by the ice the solution cannot dissolve as much sugar and so a saturated solution is formed.Explanation
When the drink is made in the factory, sugar is added to the point where a saturated solution is formed at room temperature. However, when the drink is served with ice, the temperature decreases, causing the solution to cool down. As the temperature decreases, the solubility of sugar in the solution decreases, meaning that the solution cannot dissolve as much sugar as before. This leads to the excess sugar precipitating out of the solution and appearing as solid sugar in the drink.Rate this question:
