Study Notes
Electron Configuration
- A hypothetical element with an electron configuration of 1s22s22p63s23p5 has an atomic number of 11.
- It is a member of Group V, also known as the Nitrogen Group.
- It is located in the fifth position of the p-block, along the third period of the periodic table.
Boyle's Law
- Boyle's Law states that the volume of a gas is inversely proportional to the pressure.
- An example of its application is a tire becoming harder as more air is pumped into it.
Biomolecules
- Despite the diversity among organisms, they are all made from the same set of biomolecules composed of monomeric units.
- The exception is ash from burnt rice hulls and straws, which is rich in compounds that can neutralize acidic soil.
Acid Rain
- Acid rain occurs when sulfur released in burning fossil fuels combines with water in the atmosphere.
- It does not occur when carbon dioxide combines with water in the atmosphere, or when phosphorus-rich water in lakes evaporates to form phosphoric acid.
Plant Propagation
- When a gardener propagates a plant by taking cuttings, he covers the plant and pot with a lightly perforated polythene bag to reduce transpiration and prevent water loss.
Nitrogen Cycle
- It is difficult to integrate nitrogen gas from the atmosphere into the nitrogen cycle of the biosphere because nitrogen is very abundant in the atmosphere.
- Nitrogen is not quickly absorbed by living organisms, and oceans do not quickly absorb nitrogen gas.
Biogeochemical Cycles
- After a lightning strike, mushrooms thrive due to the involvement of the nitrogen cycle.
Seasonal Winds
- PAGASA announces the approach of seasonal winds known as Amihan and Habagat, which are internationally known as Northeast and Southwest monsoon.
Food Webs
- If all snakes are killed in a simple food web, the population of frogs and grasshoppers would increase.
Fog Formation
- Fog forms when the ground has lost heat by radiation, and the air near the ground cools, causing the water vapor to condense.
Earthquake Measurement
- Intensity refers to the strength of an earthquake, while magnitude refers to the degree of destruction it causes at the epicenter.
- Intensity cannot be measured while magnitude can be measured using a seismograph.
Refrigeration
- It is not advisable to repeatedly open the door of a refrigerator because it leads to wastage in electrical energy.
Speed of Sound
- The speed of sound is usually lowest in gases and highest in solids.
- This is because the particles in a gas are farther apart, making it harder for the sound wave to propagate.
Mirrors
- A convex mirror is used in cars to give the driver a wider area and smaller image of the traffic behind.
Thunder and Lightning
- We hear thunder some seconds after seeing lightning because light travels faster than sound.
Specific Heat
- Water has a higher specific heat than iron, meaning it heats more slowly than iron.
Colorblindness
- If a colorblind man marries a woman with normal vision and no history of the disease, it is most probable that all of their daughters will be carriers.
Plant Growth
- Albino corn seedlings may grow several inches tall but will eventually die due to their inability to produce their own food.
Organismal Response
- Mimosa pudica, or Makahiya, responds to a given stimulus by closing its leaflets when touched, a phenomenon called thigmotropism.
