Study Notes
Gas Laws and Properties
- In a gas vessel, the mass of oxygen gas can be calculated given the volume, pressure, and temperature.
- Avogadro's principle states that the volume of gas is proportional to the amount of substance in moles at constant pressure and temperature.
Atomic Structure
- A deuteron is a nucleus of a deuterium atom, consisting of one proton and one neutron.
Forces and Units
- The unit "N" in a 500-N block refers to the force of 500 Newtons.
Kinetic Energy
- When two objects have the same kinetic energy, but one has twice the mass of the other, the heavier object has half the velocity of the lighter object.
Chemical Compounds
- The law of definite proportions states that when two or more elements form more than one compound, the ratio of the masses of one element that combine with a given mass of another element in the different compounds is a ratio of small whole numbers.
Atomic Radii
- The radius of a phosphorus atom is 1.10 Å, which is equivalent to 110 pm.
Gas Solubility
- Henry's law asserts that the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the solution.
Material Properties
- The ratio of lateral strain to longitudinal strain in a material is called Poisson's ratio.
- Within the elastic limit, stress is directly proportional to strain.
- The modulus of resilience is the property of a material defined as the work done in producing strain per unit volume.
- The proportional limit is the mechanical property that refers to the stress at which a material exhibits a specified deviation from proportionality of stress and strain.
- Hooke's law holds good up to the proportional limit.
Elastic Collisions
- In an elastic collision between two particles, if the initial kinetic energies of the two particles are equal, the ratio of their velocities is given by the ratio of their masses.
Simple Harmonic Motion
- To triple the period of simple harmonic motion, the weight suspended vertically from a spring coil must be changed by a factor of 3^2.
Fluid Dynamics
- Reynold's number is the ratio of inertial force to viscous force in a liquid.
- Newtonian fluids are characterized by a constant viscosity, which is independent of the shear rate.
