For answer of question number 26 see the attachment .

Hope it will help you.

Answer 2

26. A is KOH (Potassium Hydroxide) and B is Water

27. Increasing Angle of Incidence on angle of refraction proportionally increases the angle of emergence.

Explanation:

• Question 26 is an experimental set-up to prove that Carbon-di-oxide is evolved during the respiration process of plants. For this KOH, Germinating Seeds, A beaker containing water are set up.θ∅
• Due to aerobic respiration of the seeds, the water level rises in the bent tube thus proving the process of respiration.
• Question 27: Increasing the Angle of incidence on the angle of refraction increases the emergence angle. This can be determined using Snell's law.
