thanks for all the advices :) @Chestermiller I'm currently not at home so i dont know the exact data but maybe we could first work with imaginary values (if thats possible) and when i get home ill try to apply the procedure to the real data: L = 0,1m k = 0,5 W/m*K c_p = 1000 J/kg*K R = 2000...

thank you very much for your efforts. but unfortunately i'm a bit stumped because i don't know how to implement/apply this. I don't know if this is important to know, but I only have discrete values. So I only know the surface temperature at the time before heating and 20 seconds after heating

My very first thought was this: Assumption: surface temperature presents the average temperature of the whole cube (so the cube is really small/thin) First, you could calculate the heat absorbed during heating Q_h = m * c_p * (T_1 - T_0) Then the cooling Q_c = m * c_p * (T_2 - T_1) We...

Hello guys, [FONT=arial]I am currently running an experiment in my hobby room: I want to heat a cube in a microwave and then measure the surface temperature. Unfortunately, it takes about 20 seconds, so the cube cools down during this time which means I don't measure the actual temperature...

@Steve4Physics oh that was my mistake. I actually only wanted to show the function of the heating process but I accidentally let the temperature sensor continue to run after the heating process and forgot to shorten the diagram on the time axis, which is why a quadratic function is displayed and...

And the DeltaT would be T(10) - T(0)? i.e. the temperature at the end of heating minus the temperatur before the start of heating right? But can you think of any way to interpret the integral of a temperatur-time graph, even if we have to multipy/divide it by something beforehand? Or should I...

The cube is heated using a microwave "oven". Unfortunately, I cant tell you the exact distance to the heat source, but I hope that it probably doesn't matter any more (correct me if I'm wrong), as the heat is "generated" in the specimen itself because of the heating mechanism of the microwaves...

Thanks Lnewqban for the warm welcome and the quick reply. You're absolutely right. Perhaps it will help if I explain the exerpiment: I have a test specimen (cuboid) that has a hole in it. A temperature sensor is inserted into this hole to measure the heating of the test specimen from inside...

Hello everyone, hope you are all well. I have the following problem: I have a temperatur-time graph. If you determine the integral of this graph, you get the unit [kelvin*second]. This unit is as far as I know meaningless. Is it possible to mathematically "transform" the area under the curve...
