Questions and Answers

1.

A SUBSTANCE DISSOLVES IN A LIQUID TO FORM :
- A.
  
  Soloution
- B.
  
  Product
- C.
  
  Gas
Correct Answer
A. Soloution

Explanation
When a substance dissolves in a liquid, it forms a solution. A solution is a homogeneous mixture where the solute (substance being dissolved) is evenly distributed and dispersed in the solvent (liquid). This process occurs at a molecular level, where the solute particles are surrounded by solvent particles and become uniformly dispersed throughout the liquid. Therefore, the correct answer is "solution."

WATER IS A -------------------- & ICE IS A ----------------------.

Correct Answer
A } LIQUID , GAS , CHEMICAL B}SOLVENT , SOLID , SOLOUTION

Explanation
Water is a liquid at room temperature and pressure, and it can exist in the form of a gas when heated. Ice, on the other hand, is the solid form of water, which occurs at temperatures below 0 degrees Celsius. Therefore, the correct answer is A) liquid, gas, chemical. The options B) solvent, solid, solution are incorrect as they do not accurately describe the physical states of water and ice.

CONDENSATION IS THE REVERSE OF:
- A.
  
  SUBLIMATION
- B.
  
  SOLIDIFICATION
- C.
  
  EVAPORATION
- D.
  
  BOILING
- E.
  
  NONE
Correct Answer
C. EVAPORATION

Explanation
Condensation is the reverse of evaporation because it involves the conversion of a gas or vapor into a liquid. During condensation, the molecules in a gas or vapor lose energy and come together to form a liquid. This process is the opposite of evaporation, where a liquid turns into a gas or vapor by gaining energy and breaking apart its molecules.

BOILING WATER IN A KETTLE CAUSES ITS LID TO RISE AND LET OUT STEAM DUE TO:
- A.
  
  MOISTURE
- B.
  
  PRESSURE
- C.
  
  HEAT
Correct Answer
B. PRESSURE

Explanation
When water is heated in a kettle, it starts to boil and convert into steam. As the water boils, it releases steam which increases the pressure inside the kettle. This increased pressure pushes against the lid of the kettle, causing it to rise and let out the steam. Therefore, the correct answer is pressure.

WATER TURNS INTO ICE @ :
- A.
  
  I00 DEGREES CELCIUS
- B.
  
  II0 DEGREES CELCIUS
- C.
  
  O DEGREES CELCIUS
Correct Answer
C. O DEGREES CELCIUS

Explanation
Water turns into ice at 0 degrees Celsius. This is because at this temperature, water molecules slow down and come closer together, forming a solid crystal lattice structure. Below 0 degrees Celsius, water molecules lose enough energy to freeze and become ice. Therefore, 0 degrees Celsius is the freezing point of water and the temperature at which it turns into ice.

POURING A PINCH OF SALT ON THE SURFACE OF CUBIC ICE CAUSES IT TO :
- A.
  
  FREEZE
- B.
  
  EVAPORATE
- C.
  
  BOIL
- D.
  
  MELT
Correct Answer
D. MELT

Explanation
When a pinch of salt is poured on the surface of cubic ice, it causes the ice to melt. This is because salt lowers the freezing point of water. When salt is added to ice, it disrupts the ice crystals and prevents them from forming a solid structure. As a result, the ice starts to melt and turns into liquid water.
