[@wynter_true6103]

There is a correction in evaporation stage ,the intermolecular forces are broken because they were already weakened in the melting stage.

[@KCSEBIOLOGY]

please confirm which time in video.. .

[@wynter_true6103]

1.01

[@KCSEBIOLOGY]

melting and weakening in this case ni still correct. some books say they weaken some say they break. however, in physics we see that energy can never be broken or diminished, its only converted to another form.. therefore, hi ni biology, weakening or breaking of the force, is same thing according to our case

[@annjanty4852]

Thanks so much. I'm a bit confused in solubility part in chromatography. We were told by our chem teacher that pigments which are more soluble and less adsorbed are carried furthest

[@KCSEBIOLOGY]

this is a great insight 😱

[@IreneChepleting-n1x]

So is it correct??

How do you know that a graph is pure or impure..... ?!

[@KCSEBIOLOGY]

a pure graph has sharp melting and boiling point. an impure graph doesnt have sharp melting and boiling point.

[@MurdhiaHassan]

When giving the point on difference between luminous and non luminous , how would you give the point on being sooty without using a negative statement on non luminous

[@KCSEBIOLOGY]

you could say, the Luminous flame produces more soot while the non luminuous flame produces less soot

[@sadana_57]

I have a question concerning luminous and non luminous flame . Our chem teacher taught us that in luminous we say has less heat and more light as separate points and non luminous we say more heat less light . But you mentioned at 47:55 that we should avoid negative answers . So is using less light / less heat okay?

[@KCSEBIOLOGY]

Heey sasa. The teacher is very right.. by negative i meant,, like example;; Luminous produces light while Non Luminous does NOT produce light. Using NOT is negative so avoid using this.. Your teacher also avoided the negative. You see instead of the teacher saying Does NOT, he said that Non Luminous produces less light, which is right. So interms of Light and Heat. We can say this to avoid using NOT. *Luminous produces much light while Non Luminous produces less light. (Dont say Non Luminous does NOT produce light. Utapata wrong) *Luminous produces less heat while Non Luminous produces much heat. (Dont say Luminous does NOT produce heat. Utapata wrong)

What are the uses of bases for a form 1

[@KCSEBIOLOGY]

hallo. if you are to mention uses of bases,, mention a specific base, then its use.. do not generalize and say bases are used for this or that. mention a specific base and say its use as explained below;;; 1. **Sodium Hydroxide (NaOH)** - **Soap Making:** Used to produce soaps and detergents by saponifying fats and oils. - **Paper Manufacturing:** Employed in the pulping process to separate lignin from cellulose fibers. - **Drain Cleaning:** Common ingredient in drain cleaners to dissolve organic matter. 2. **Potassium Hydroxide (KOH)** - **Biodiesel Production:** Used as a catalyst in the transesterification process to produce biodiesel from vegetable oils or animal fats. - **Battery Electrolytes:** Utilized in alkaline batteries as an electrolyte. 3. **Calcium Hydroxide (Ca(OH)₂)** - **Soil Treatment:** Known as lime, used to neutralize acidic soils in agriculture. - **Water Treatment:** Used to soften water by removing carbonate hardness. 4. **Ammonia (NH₃)** - **Fertilizers:** Used to produce various nitrogen-based fertilizers, such as ammonium nitrate. - **Cleaning Products:** Commonly found in household cleaners for its effectiveness in breaking down grime and grease. 5. **Magnesium Hydroxide (Mg(OH)₂)** - **Antacids:** Used in medications like milk of magnesia to neutralize stomach acid and relieve indigestion. - **Laxatives:** Acts as a laxative by drawing water into the intestines. 6. **Sodium Bicarbonate (NaHCO₃)** - **Baking:** Used as a leavening agent in baking to cause dough to rise. - **Fire Extinguishers:** Component of some fire extinguishers for its ability to produce carbon dioxide and smother flames. - **Cleaning Agent:** Used as a mild abrasive and deodorizer in household cleaning products. 7. **Calcium Carbonate (CaCO₃)** - **Construction:** Used as a primary component in cement and mortar. - **Antacid:** Used in over-the-counter antacids to neutralize stomach acid. 8. **Lithium Hydroxide (LiOH)** - **Batteries:** Used in the production of lithium-ion batteries. - **Carbon Dioxide Scrubbers:** Employed in spacecraft and submarines to remove CO₂ from the air. These specific examples illustrate the diverse applications of bases in various fields.
