Hi
I have a test in the next week on Thermal Physics but we have not yet covered specific latent heat.
The spec says: "Calculations including continuous flow."
What are these calculations?
Thank you

Q is heat absorbed/released during a phase change (J), L is specific latent heat (J kg^-1)
L quantifies how energy consuming/releasing a substance is when undergoing a phase change, controlling for mass.
Heat is absorbed in endothermic processes e.g) solid -> liquid -> gas. The reverse phase changes are exothermic (heat released).
When a phase change occurs, temp is constant. Q = mcΔT involves temp changes i.e) whilst substance maintains phase.
Each substance has 2 L values, 1 for melting point (solid/liquid) and 1 for boiling point (liquid/gas).
