That pretty well applies to all matter. Whenever matter is heated, it expands. Maybe, what you intended to ask is what substance heats up when it expands. If that is your question, the answer is HYDROGEN. In fact, it can heat sufficiently to autoignite. This is one of the hazards associated with working with compressed hydrogen.

By the laws of physics, when the temperature of a substance is increased, its volume also increases. It is a derivation of Charles Law, a gas law that states the volume of a gas will increase when its temperature is increased. And vice-versa. The only exception is 'water'. It's volume will increase when its temp is decreased below freezing. So essentially, pick whatever substance you want, and it's volume will increase (it expands) when it's heated. Some substances expand at faster rates than others. This principle is used in the making of thermostats.

many substances will expand once heated because of an increase in the kinetic energy of its particles which allows them to move farther apart from each other. Hence expanding the substance. some substances which will expand are solids like metals (eg. mercury in a thermometer), gas particles expand to fill the entire container and once heated they will move even faster and farther apart and liquids also expand once heated so much so that the particles of the liquid eventually leave the liquid as a gas (ie. boiling or evaporation).

006 is correct, all substances expand as the temerature is increased. There is though, the exception of the H20 phase change from ice to water in which it acually contracts due to the geometry of the strong hydrogen bonds which are formed only at lower temperatures (0ºC at 1 atm).

That's just about every substance.

Umm, gas?
Oh, not water between 0 and 4C. Water contracts at those temperatures (which is why ice is less dense than water)

Ummmm... that 's just about every substance that I know of.
