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
2.6 x 1000 = 2600
2600÷(0.80x80) = 40

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

2.6 x 1000 = 2600
2600÷(0.80x80) = 40

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

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