Seconds, aren't i supposed to be using that? This is confusing lol.
I always get told you're supposed to use SI units, and for mass that's kg and time s :(
This still isn't making sense to me:
Right so the equation for specific heat is:
c = q/(m*delta t) right?
So if we are using 6.8 x 10^ 5 as q, and 1500grams for mass, and change in t is 322 seconds, that would give us:
c = (6.8 x 10^5)/((1500)(322))
But that gives me an answer of like 1.4...
Homework Statement
mass, m, of water in kettle
1.5 kg
power rating, P, of kettle
2.1 kW
time interval, t, for heating
322 seconds
starting temperature
4 °C = 277 K
finishing temperature
100 °C = 373 K
temperature change, ΔT
96 K
electrical energy supplied, E = P × t...
