The first-order phase transitions
between a two-dimensional (2d) gas and the
2d solid of the first monolayer have been studied for the noble gases
Ar, Kr and Xe on a NaCl(100) surface in
quasi-equilibrium with the three-dimensional (3d)
gas phase.
Using linear temperature ramps,
we show that the widths of the hysteresis
loops of these transitions as a function of the
heating rate, r, scale with
a power law 
, with α between 0.4
and 0.5 depending on the system.
The hysteresis loops
for different heating rates
are similar. The island area of the condensed layer was found to grow
initially with
a t4 time dependence.
These results are in agreement with theory,
which predicts 
and hysteresis loop similarity.
