I'm pretty sure it is Chemical store to kinetic store to gravitational store, remember it was all only 4 marks so they wouldn't be expecting you to write any more that 5 per category

yeah i think it will be 2 marks for the first point and one for the other two

Yh I thought that as well but there was a question where u had to round to 2SF so I think that played a part as well

Oh I got some crazy numbers for that question :s-smilie:

Yh there wasnt even that much u could say for that
thats why i talked about particles having more energy and the internal energy increasing as well

same i said that

I put something like this i believe:
The increase of temperature means particles have more kinetic energy meaning they travel at higher speeds which increases the probability of the particles colliding which generates more internal energy. In addition to it the concentration, means more particles per the volume of the pressure cooker meaning greater chance of collision happening meaning more energy generated. - basic answer of what I put, expanded my points a bit more

Yh probably, science are quite generous with the mark scheme

Did anyone get 3.4 for one of the calculation 5 markers?

omfg same i ended up rounding it to like 34,000,000,000 i think

What numbers did u get! Mine was like 3.4 x 10 to the power of -6 😭😭

I think the answer was just 3.4 because you had to divide it by 1000 to get the amps

3.4 beccause you had to divide milliamps by 1000

i got A B D C, i calculated the gradients of each, the higher gradient the more unstable- it link to the decay formuka which is activity/time period, which is the same as the axis
