RP: Osmosis

What is the purpose of using a cork borer in the experiment?

• To measure the mass of the potato cylinders

• To ensure all potato cylinders have the same diameter

• To record the length of potato cylinders

• To mix different sucrose solutions

Why is it important to have potato cylinders of the same length?

• To compare results more easily

• To facilitate uniform absorption of solutions

• To ensure accurate weighing

• To make it easier to mix solutions

What tool is used to measure the length of potato cylinders?

• Balance scale

• Ruler

• Vernier calipers

• Cork borer

What does the experiment aim to demonstrate with different sucrose solutions?

• The boiling point of water

• The effect of sugar on boiling water

• The impact of solution concentration on osmosis

• The solubility of sucrose in water

What is the significance of using a top pan balance in this experiment?

• To accurately measure the mass of cylinders

• To determine the sugar concentration

• To measure temperature changes

• To mix solutions more effectively

What change was observed in the potato cylinder placed in distilled water after 24 hours?

• Decrease in length

• No change in mass

• Increase in mass

• Decrease in mass

What does an increase in mass of the potato cylinder indicate about osmosis?

• Water is leaving the potato cells

• Sucrose is entering the potato cells

• No osmotic activity is occurring

• Water is entering the potato cells

Why might the potato cylinders need to be dried before weighing?

• To remove excess water that might skew mass measurements

• To prevent evaporation

• To cool down the samples

• To make them easier to handle

How is the percentage change in mass calculated in the experiment?

• (Initial mass - Final mass) / Final mass * 100

• (Final mass + Initial mass) / Initial mass * 100

• (Final mass - Initial mass) / Initial mass * 100

• Final mass / Initial mass * 100

What does the graph in the experiment illustrate?

• Temperature changes in the solutions

• Changes in pH level due to sucrose

• The relationship between sucrose concentration and mass change

• The boiling points of different sucrose solutions
