Homework Statement
380g of a liquid at 12'C in a copper calorimeter weighing 90g is heating at a rate of 20 watt for exactly 3 minutes to produce a temperature of 17'C. If the specific heat capacity of copper is 40Jkg-1K-1, the thermal capacity of the heater is negligible, and there is a negligible heat loss to the surroudnings, obtain a value for the specific heat capacity of the liquid.
Homework Equations
VxI = MC(x2 - x1) + q
The Attempt at a Solution
I genuienly don't have a clue about this.
+q is negligible.
So what are we meant to do for this? I assume we get two values for the equation of the calorimeter and the liquid, minus them and make it C =.
Is that correct? But what values do we sub in for where (I know what everything stands for =/).
Any help is apprectiated!
Thank you.
