    Heat Measure
AI Thread Summary
To measure the transfer of heat from a heater to a solid, it is essential to assume that all the power from the heater, measured in watts, is directed entirely to the solid without any energy loss to the environment. In this ideal scenario, watts can be converted to joules per second, allowing for the calculation of energy transferred by multiplying the heater's power by the duration it operates. The fundamental principle is that the energy lost by the heater equals the energy gained by the solid. This relationship can be expressed using the formula Q = (mass of the solid) * (specific heat capacity of the solid) * (rise in temperature), where Q represents the heat transfer. This approach is suitable for basic physics calculations, though real-world applications will typically involve some energy loss.

*eh hem*, this is my first post in this forum and i have a query on heat transfusion, i think i have the right forum though.

how do you measure the transfer of heat from a heater of certain watt's to a solid of certain mass?

thank you in advance,
ben

FIrst, you have to make a huge assumption that the "watts" (this is the power of the heater) is going entirely into the thing being heated, and none of the energy is leaking into the atmosphere or anything else. For beginner physics this is OK, although int he real world you can be guaranteed that some energy will go elsewhere.

So, since "watts" is the same thing as "joules per second", then you multiply "watts" times the number of seconds that heater is on. Heat is the transfer of thermal energy. Power times times equals energy.
 
well in a perfect system

energy lost by your heater = energy gained by the solid
Q = (Mass of solid)*(specific heat capacity of solid)*(rise in temp)
 

Thread 'Entropy and configurations of microstates'

I was watching a Khan Academy video on entropy called: Reconciling thermodynamic and state definitions of entropy. So in the video it says: Let's say I have a container. And in that container, I have gas particles and they're bouncing around like gas particles tend to do, creating some pressure on the container of a certain volume. And let's say I have n particles. Now, each of these particles could be in x different states. Now, if each of them can be in x different states, how many total...

Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'

Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...
