for the methods of each practical, where do i get them because you gave the method for this topic in this video but not for some of the rest of the topics
Im a bit confused because my teacher taught us this in college the other day but told us we have to divide the 'heat energy released' value by 1000 before calculating the 'energy released per mole value' but you havent done that. Does it matter?
I suspect that you are confusing the mass of the fuel burned, the molar mass of the fuel and the mass of the water heated. 100ml of water has a mass of 100g
And all 5 practicals pls
This has made the practical stick so much better in my head, and I’m terrible at maths
great to hear from you

There are a bunch of practicals that you should be familiar with. You should have done them in your lessons. Look at my other unit 3 videos
You're going to be the only reason i pass. Can you please please go through a past paper ❤
THANK YOU SO MUCH!!
you're welcome
Can u go through a past paper pls before the unit 3 exam?

it depends on the units you are using for specific heat capacity
kJ / kg C or J / g C
1kJ = 1,000J
@@btecappliedsciencehelp oh, thank you
is the m just 100 by default, and is the delta T 20.5 by default?
I said the temperature rise was about 20 so there is some variation
100ml of water is used each time measured with a measuring cylinder
