ok so i have to find the specific heat capacity of a metal.
the question says: draw a graph of time vs temp (which i have done) and from the equation E=mCÄè calcuatle the specific heat capacity? and ideas?
the second part is i have to calculate the thermal conductivity of a metal rod using this formaular: Q/t = ëA ((è2 - è1)/X) i dont know if i have to rearange this, but i have to find ë (thermal conductivity) i think x is length of rod, theta1 - theta2 is the temp difference, A is the cross sectional area...sooo any ideas, im truly stumped

" The specific heat capacity (the symbol c or s, also called specific heat or SHC) of a substance is defined as heat capacity per unit mass. The SI unit for specific heat capacity is the joule per kilogram kelvin, J·kg-1·K-1, which is the amount of energy required to raise the temperature of one kilogram of the substance by one kelvin. Heat capacity can be measured by using calorimetry."

haha no, but that helps a bit thanks

Jezza you have missed out a lot of important details of your experiment and I do not immediately recognise all the symbols used in your equation. You need to give a lot more detail before it is possible to answer your questions fully.

yea it wasnt like that when i did it, umm è is meant to be theta, and this ë, is lambda
oh yea and this Ä, is delta
