Plasma
It is found to be in the fourth State of Matter - Plasma: Proxima Centauri is a Star.
It is a highly charged plasma.
Proxima Centauri's surface is believed to be in a plasma state, as it is a red dwarf star. This means that its atoms have been stripped of their electrons, creating a highly ionized and extremely hot environment.

The movement of matter in the sun due to temperature differences is known as convection. Hotter material near the Sun's core rises while cooler material near the surface sinks, creating a continuous cycle of convection currents. This movement of matter helps transport heat from the core to the surface, contributing to the Sun's energy emissions.
It is challenging to find a material that can withstand the temperature of the surface of the Sun, which is around 5,500 degrees Celsius. Tungsten has one of the highest melting points of any metal at 3,422 degrees Celsius and is used in high-temperature applications, but even it would not survive the extreme heat of the Sun's surface.
Alpha Proxima, but don't think it will matter, all life on earth will end pronto.
No. Temperature is a property of matter - just like mass or length.
A liquid has surface tension.
how temperature can bring about changes in the state of matter
When you add energy to matter, its temperature increases. This is because the added energy increases the kinetic energy of the particles in the matter, which manifests as a rise in temperature.
Cold is not a matter, it is a characteristic of a matter (a low temperature).
