EOG Matter Review

Front

What process allows green plants to control the amount of water stored in their leaves?

Back

Transpiration is the process by which plants release water vapor into the air, helping them regulate water levels.

Front

What is the total mass of a solid formed when 200 grams of liquid 1 and 100 grams of liquid 2 are mixed?

Back

The total mass of the solid substance formed is 300 grams, as mass is conserved in chemical reactions.

Front

What could cause grass to be wet in the morning if it didn't rain?

Back

When the air cooled overnight, water vapor condensed on the grass, causing it to be wet.

Front

What does the Law of Conservation of Matter state?

Back

The Law of Conservation of Matter states that the total amount of matter stays the same after it undergoes change.

Front

What process is responsible for the disappearance of a puddle of water after a sunny day?

Back

Evaporation is the process that causes the puddle of water to disappear as it turns into vapor.

Front

Define photosynthesis.

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What is condensation?

Back

Condensation is the process by which water vapor in the air cools and changes into liquid water, forming droplets.

Front

Explain the term 'evaporation'.

Back

Evaporation is the process by which liquid water turns into water vapor, usually due to heat.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is respiration in plants?

Back

Respiration is the process by which plants convert glucose and oxygen into energy, releasing carbon dioxide and water.
