A sparsely planted forest is likely to have small scale fires while a densely packed one has the potential to burn completely — this shift is called a phase transition.
A cup of warm water is suspended in a large pot of boiling water. Will the water in the cup ever boil?
Assume that the pot never runs out of water.
For how many seconds would you need to focus the Fresnel lens on a penny in order to melt the entire coin?
Details and assumptions:
Suppose you have a glass of water that contains an ice cube. What happens to the water level in the glass when the ice melts?
When \(\displaystyle T\) crosses \(T_c\), however, there is a qualitative shift in the allowed values of \(m^*\), and the system undergoes a phase transition.
Suppose we're working with the system at a temperature \(\displaystyle T\) below \(T_c\) such that \(T-T_c=-10\), find \(\lvert m^*\rvert\).
