What materials heat up under pressure and for how long?

what materials heat up under pressure and for how long??

I was just wondering are there any two rocks or combination of rocks that when their flat surfaces are pushed together cause heat? If the pressure is very high is that heat quite considerable??

or maybe there are liquids that do the job better? are there any two materials that heat up when under pressure??

and if under a constant pressure do they stay in a constant elevated heat state?

I'm sure a physics guy here would have the abilities to find that type of material even if it was lost

Temperature and pressure are independent from each other. High pressure does not cause heat. Said that, it's probably worth also mentioning the fact that increasing the pressure on a gas may cause its temperature to increase due to mechanical work - not heat - done on the gas.

Air works well for that.

But constant pressure will not do anything.
Energy equals Force times distance. (force applied to an object times the distance over which that object is being pushed.)
If the pressure is constant and nothing moves the distance is zero.

Work is force times distance. With seismic events, the Distance can be very small but the Forces are huge. The heat tends to be generated most when there's 'sliding' between plates. Look up Subduction. You get a lot of volcanoes in subduction zones.

I can tell you that any material can potentially heat up under pressure, but the amount and duration of the heat will vary depending on the specific properties of the material. Generally, materials with low thermal conductivity and high compressibility, such as certain types of rocks and minerals, can experience a significant temperature increase when placed under high pressure. The amount of heat generated will also depend on the amount of pressure applied and the duration of the pressure.

In terms of liquids, some fluids such as gases and oils can also experience a temperature increase when compressed, but again, the extent of the heating will depend on the specific properties of the liquid and the amount and duration of the pressure.

As for whether the materials will stay in a constant elevated heat state under constant pressure, it will also depend on the material's properties and the level of pressure applied. Some materials may reach a thermal equilibrium where the temperature remains constant, while others may continue to heat up as long as the pressure is applied.

In terms of finding a specific material that can generate a significant amount of heat under pressure, it would require further research and experimentation. It is possible that such a material may have been discovered in the past, but it may not have been widely known or utilized. I would be interested in exploring this topic further and potentially discovering new materials with unique properties.
