4 Multiple choice questions
- Electric current is equal to the potential difference across the conductor divided by resistance (I=v/R)
- When a substance is dissolved in a solvent, the solution formed will have a lower freezing point, higher boiling point, and less vapor pressure than the pure solvent.
- Galaxies recede from each other with a velocity proportional to their distance.
- The total pressure of a gas mixture is equal to the sum of the partial pressures of the components
4 True/False questions
Coulomb → The force between two electric charges is inversely proportional
to the square of the distance between them and directly proportional to the product of their charges
Henry → The solubility of a gas in a liquid is directly proportional to the partial pressure of the gas
Snell → The ratio of the sine of an angle of incidence to the sine of the angle of refraction is a constant.
Charles → Galaxies recede from each other with a velocity proportional to their distance.
