- 2. _____________ number is a term used in colloidal chemistry. It is defined as the minimum amount of protective colloid in milligrams which prevents a color change from red to violet of 10ml gold sol by the addition of 1 ml of 10%NaCl solution.
- 3. A capacitance of 2 µF is required in an electrical circuit across a potential difference of 1.0 kV. A large number of 1 µF capacitors are available which can withstand a potential difference of not more than 300 V. The minimum number of capacitors required to achieve this is
- 7. An electric dipole has a fixed dipole moment p → , which makes angle θ with respect to x-axis. When subjected to an electric field → ∧ E E 1= i , it experiences a torque → ∧ T1= τ k . When subjected to another electric field → ∧ E 3 E 2 1 = j it experiences a torque → → T T 2 1 =− . The angle θ is
- 8. ∆U is equal to ______ work

- 13. is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells. It occurs concurrently with two types of nuclear division called mitosis and meiosis, which occur in animal cells.
- 15. the second stage of cell division, between prophase and anaphase, during which the chromosomes become attached to the spindle fibres.
