    Specific Heat Capacity of water in a kettle

    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 :(

    Specific Heat Capacity of water in a kettle

    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...

    Specific Heat Capacity of water in a kettle

    Oh..But i thought you always take the mass in SI which is kg? Ok thanks

    Specific Heat Capacity of water in a kettle

    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...
