Grade 6 Chemistry Quiz: Condensation and Hydrolysis

Condensation is the process of ________ turning into liquid.

• plasma

• solid

• light

• gas

What is the primary factor that affects the rate of evaporation?

• Humidity

• Wind speed

• Temperature

• Pressure

Explain the concept of humidity in relation to condensation.

• Humidity is the amount of carbon dioxide present in the air, and high humidity can lead to condensation.

• Humidity is the amount of dust present in the air, and high humidity can lead to condensation.

• Humidity is the amount of oxygen present in the air, and high humidity can lead to condensation.

• Humidity is the amount of water vapor present in the air, and high humidity can lead to condensation.

Give an example of a real-life situation where condensation occurs.

• Glass of cold water on a hot day

• Melting ice cream

• Boiling water

• Burning wood

What is hydrolysis in the context of carbohydrates?

• Chemical reaction in which a compound is built up by the addition of water

• Chemical reaction in which a compound is broken down by the addition of carbon dioxide

• Chemical reaction in which a compound is broken down by the addition of water

• Chemical reaction in which a compound is broken down by the addition of oxygen

How does hydrolysis break down carbohydrates?

• By using heat to break the chemical bonds

• By using water to break the chemical bonds between the carbohydrate molecules.

• By using air to break the chemical bonds

• By using light to break the chemical bonds

What are the products of hydrolysis of carbohydrates?

• Complex sugars

• Simple sugars

• Proteins

• Lipids

Explain the role of enzymes in the hydrolysis of carbohydrates.

• Enzymes speed up the synthesis of carbohydrates

• Enzymes have no role in the hydrolysis of carbohydrates

• Enzymes break down complex carbohydrates into simpler sugars.

• Enzymes convert carbohydrates into proteins

Provide an example of a carbohydrate that undergoes hydrolysis in the human body.

• Protein

• Water

• Vitamin C

• Starch
