The answer to physics is calculations.

The answer to the 6 marker was 40

what 6 markers?

I got 40 for the 6 mark specific heat thing

how, it was asking for the specific heat capacity of water?

I got 4800 for spec heat cap

(edited 4 years ago)

for the specific heat capacity of water, it was 4751, converted to 2sf is 4800

6 marker on specific heat capacity:
Had to calculate E(energy transferred) by using E = P X T as you were given the power and time was 120 seconds if I tenner correctly. However the power was in Kw so you needed to convert to watts. Then sub in to specific heat capacity equation.

yeh, i used the energy transfered equation [power(W) x time(s)]. converted kW to W and i got 312000J. Rearranged the specific heat capacity equation to find specific heat capacity and got 48000J/kg °C

how did you get that mate? i got 4800J/kg°C

how did you get that mate? i got 4800J/kg°C

2.6 x 1000 = 2600
2600÷(0.80x80) = 40

Yeah I got it 6 marks in the bag.

No mate, first part is correct but then you would multiply 2600W by 120s to give 312000J and then do 312000/(0.80 x 82) = 4756.09756
= 4800J/kg°C

Original post by Paolo3100

2.6 x 1000 = 2600
2600÷(0.80x80) = 40

how was the specific heat capacity question worded? can't seem to remember it

did the paper have two 6 markers?

Yeah, one was about the movement of air molecules of the different states of argon, and the other was a calculation of specific heat capacity

did the paper have two 6 markers?

anyone else get something like 0.1212 for the mass of water

Original post by Paolo3100

The answer to the 6 marker was 40

no it wasnt ur meant to use another equation because u needed thermal energy change

Did anyone get 14:19 for ratio question at the end?
