Heat transfer / dissipation

Physics Asked by Dubi Katz on September 18, 2020

I have a hollow cylinder made of material A (eg. glass).
Inside the cylinder I have some liquid (material B, eg. water).

On the outside of the cylinder, wrapped around it, I have a metal wire (material C, eg. copper).
We use the resistance of the wire with the appropriate current to generate heat.

All parameters are known apriori (room temperature, materials’ temperature, volume, etc.).

The questions:
(1) Paramterically, how do I calculate the time it takes to heat the material inside the cylinder to
a target temperature?
(2) Similarly, once I turn off current to the wire, how long for the material inside the cylinder to cool down to a target temperature?

Thanks!
