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

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?

@MrRuelTuition 8 ай бұрын

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"

Sir, how to write if relationship is asked between food sample and energy value?

@MrRuelTuition 8 ай бұрын

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".

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??

@nuurerdeynaa7132 8 ай бұрын

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.

@MrRuelTuition 8 ай бұрын

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.

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

@MrRuelTuition 8 ай бұрын

This answer is as complete as I can come up with. Make sure it has - RV depends on MV - which is shown by OBSERVATION

@somethingcrazy2784 8 ай бұрын

Also teacher the operation definition is RV depends on the MV right?

@MrRuelTuition 8 ай бұрын

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

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.
