Heat isn't so much about a particular chemical makeup as it is about a property of matter; how fast the particles vibrate, or in other words, a kind of random kinetic energy of the components of matter. The more violently they vibrate, the hotter the substance is. On a microscopic scale, heat is manifest as translational motion (for example, gaseous atoms or molecules traveling at high speed), vibrational motion (for example, atoms in a molecule bouncing around a specific position in their bond), and rotational motion.
Microwaves can heat up other substances besides water. They work by causing molecules in food to vibrate and generate heat, so they can heat up a variety of materials, not just water.
water
Substances with low specific heat capacity include metals like aluminum and copper, as well as gases like helium and hydrogen. These substances heat up and cool down quickly compared to substances with higher specific heat capacities.
A substance that has a low specific heat needs less heat to increase its temperature. In other words under a constant heat flux it will heat or cool more quickly than the higher specific heat substances.
Heat patches contain substances that react with oxygen to produce heat when exposed to air. This reaction generates heat that warms up the patch when it is removed from its packaging and exposed to the air.
friction
Substances with high specific heat capacities require more energy to heat up a unit mass by 1 degree Celsius. Water has one of the highest specific heat capacities of common substances, meaning it requires a significant amount of energy to raise its temperature. Metals like lead and mercury, on the other hand, have lower specific heat capacities and require less energy to heat up.

Substances with low specific heat have the ability to heat up or cool down quickly with a small amount of energy. Common examples include metals like copper and aluminum, which have low specific heat compared to substances like water.

Empty dishes do not heat up in a microwave because there is nothing for the microwave energy to interact with and convert into heat. The microwaves require water molecules or other substances to absorb them and generate heat, which is why only food or liquids heat up in the microwave.
