![[MRSM Taiping] Biology : Energy Value in Food Sample Experiment by Cikgu Shairah](/img/1.gif)
Thank you again sir, chemistry was good but they gave procedure so biology is going to be unguided. Again thank you very much for this amazing work and explanation
It's my pleasure. One more to go. 💪🏼💪🏼💪🏼
i am forever grateful for your videos sir. I've been watching your 3 videos on amali and whether it helped me or not, I'm just grateful for it. thank you so much sir.
ps: so far your videos did help😊
You're most welcome 😊
Thank you Mr.Ruel, your videos helped me a lot! Physics and chemistry was good thanks to you 🙏🏻
I'm very glad to know that! All the best for the last Amali 🔥🔥🔥
thank you for the chemistry video sir.. i really did well today
You're most welcome. I'm glad you managed to do well
Thank you sir for these 3 days. I really hope tomorrow experiment going to be smooth. Mind if I ask, what would be the operational definition for this experiment and the energy value itself?
I dare not give you one because of the inconsistencies in the mark schemes for this year itself. Even with last year there are inconsistencies. I can only advice you to use
- "RV depends on MV"
- "which is shown by OBSERVATION"
Hi sir.. i just saw this video.. quite helpful and nice explanation..
At the same time could you can make a video regarding topics we have to focus highly for biology this year spm?
I will definitely be doing SPM last minute revision closer to the actual Paper. Subscribe so you don't miss any post 😁
@@MrRuelTuitionthank you sir.. im waiting for the topics which are highly possible to come out..😃
Sir, for the 2nd precaution step how should you write it? just write "after the groundnut has completely burnt" ?
Yeap just add it to the sentence like that.
4:00
thank you very much sir i felt nervous right away for bio when i saw chem's paper got procedure
It's alright. Just remain calm, read the question carefully, and power through 💪🏼💪🏼💪🏼
thank you so much for your encouragement sir ! @@MrRuelTuition
Hi teacher, what if our mounting needle is already fixed in a cork, how do we write the procedure with that part
You can use the same line that I used in the procedure but replace plasticine with cork.
23:39 Sir nak tanya graf ni nak plot ikut skala macam mana boleh tolong jelaskan, terima kasih ❤
Paksi y memang boleh ikut skala seperti biasa, tetapi paksi x tiada skala. Hanya ada dua sampel makan sahaja
2:06 sir can I write the fixed variable as the volume of distilled water?
Tqvm for this video sir, truly grateful. 🙏
Technically it is the same, but I would stick to mass as that is the choice in the textbook.
@@MrRuelTuition ok sir, tqvm
Sir, how to write if relationship is asked between food sample and energy value?
It is not very likely for this to be asked, but if it does come out, you can do comparison. "X has a higher energy value than Y".
thank you sir ! your chemistry video saved me!😅
You're most welcome! I'm glad it helped
Sir what if i said “set apparatus as shown in the diagram” will my mark be deducted?? Or should i just mention it to be more specific??
my tution teacher mentioned that if you do this you will not get full marks for that question. Only do this if you are running out of time.
According to all the sample markschemes for 2023, the full procedure is required. However, they will only award marks for "method to control variables" and "safety precaution". If you really can't remember all, then at least you must list this down.
@@MrRuelTuition owhhhh i see… thanks a lot sir!
we love you sir thank you so much
You're most welcome 😁. All the best 🔥🔥🔥
thank you sirrr
You're welcome. All the best!
thank u sir wish for me to do well tomorrow !!
All the very best!
Hi sir,
Energy value is the total amount of heat released when food sample is
burned completely and it is shown by the final temperature of distilled water
affected by different types of food sample.
Can I use this as my answer for operational definition sir?
Or is there any other sample answer, sir?
Thank you
This answer is as complete as I can come up with.
Make sure it has
- RV depends on MV
- which is shown by OBSERVATION
Okay sir thank you @@MrRuelTuition
Also teacher the operation definition is RV depends on the MV right?
This is the usual practice. However I cannot confirm this as even the markschemes within this year are contradictory.
I advice my students to include
- RV depends on MV
- this is shown by OBSERVATION
Thank you sir
You're most welcome. All the best! 🔥
sir temperature must write in one decimal place?
Yes, since we are using a thermometer to determine the temperature
hi sir thermometer in my school is one division represent one degree
should i need to write in 1d.p,? @@MrRuelTuition
thank you so much sir. just finished chemistry exam and your video helped a lot ❤
I'm really glad it helped. Last Amali. Let's go!
Hi excuse me sir, for hypothesis i answered higher the...., higher the..... im worried because i didn't say increase/decrease... please tell me it can be accepted
higher temp hcl,shorter time taken
to dissolve completely,so correct
@@chokyikzan thank you
Can no problem. Don't worry about it. It is finished.
Can the CV be volume of distilled water as well teacher?
Technically yes, but I always advice my students to follow textbook, which is mass of water.
for 25:24 isn’t it heat energy instead of js energy tc ?
Yes, you are right. It should be heat energy.
Sir, is it lipid > protein > carbo or
lipid > carbo > protein??
Actually carbohydrates and proteins are the same. Lipid is slightly more than double the value.
I see, tqsm sirr!
Mr.Ruel thanks a lot but my chemistry 1/time against temperature graph is curve ! It shouldn't be.😭
It is correct
According to form 6 syallabus.. 1/Time over temperture is curve graph and shouldnt pass the origin because rate of reaction stopped completely only when temperature is -273..
So yeah i think you did well during exam
Don't worry. Theoretically it should be a curve.
@@sd.kfz.2kettenkrad390 thanks :) i hope i did well but depend on textbook it should be a straight line.
@@MrRuelTuition ow thanks a lot :)
Someone boiled the HCl using measuring cylinder and the measuring cylinder broke and spilled hcl everywhere today
Lol,someone in my class broke both the beaker and temperature in one go
I hope no one was injured
My chemistry graph is false😢
Don't worry about it. Graph is only one part. You've done your best. Focus on the next!
My data is weird 😢
Me 2 I get higher temperature but lower rate of reaction😢 my graph is curve decreasing lol
i thought my teacher lying energy value coming out
There is a possibility that energy value will come out.
lol hahaha
Thank you again sir, chemistry was good but they gave procedure so biology is going to be unguided. Again thank you very much for this amazing work and explanation
But there is no rule saying that it must have one unguided what. Have possibilities that 3 subjects is guided
@shawnwong3231 Really? I don't know man my teachers told me one of them might be unguided
You're most welcome. It's true that there is a possibility that all are guided, but it's good to be prepared.
