The heat can be used to boost the thermal expansion of the liquid air.
The researchers also included projections for sea level rise in Europe that includes the effects of thermal expansion, ice melt and storm surges.

The other significant factor being the thermal expansion of seawater itself.

The probe was repeatedly turned towards and away from the sun, in the hope that thermal expansion and contraction would free the antenna, but to no avail.
While ice melt is a major contributor to the height of the seas, there are other important factors especially thermal expansion caused by the warming of the waters.

The leads also need to be flexible enough to deal with the large thermal expansion of the chip relative to the plastic on which it is mounted yet another engineering headache.
The agency said worse case scenarios, including the contribution of polar ice melt and thermal expansion, could result in much higher levels occurring but these were now thought to be unlikely.
The main difference between the thermoacoustic system and Stirling's original idea is that, instead of using thermal expansion of the working fluid to push the piston, it uses powerful pulses of sound.

Now on the scale of the next century, the projections are suggesting that, between the ice and thermal expansion of the ocean, that we're likely to see upwards of a meter of sea level rise.
The study estimates that roughly half of that 0.43 inch rise was caused by thermal expansion of the oceans (as water warms, it becomes less dense and expands), some from from runoff from melting glaciers, and the rest from melting of Greenland and Antarctica ice sheets.
