yes solids do burn.
No, there are plenty of solids that don't burn. Rocks, for example, don't burn (not including coal, which is a kind of rock). If all solids burned, the entire planet Earth would have burned up a long time ago, leaving nothing but ashes floating in space.
to burn liquids and solids
Solids (like cotton) do not burn unless they release volatile organic compounds. It is these released volatiles that actually burn, not the solid itself.
Flammable substances are those gases, liquids and solids that will ignite and continue to burn in air if exposed to a source of ignition.
A substance's ability to burn is called its flammability. It refers to how easily a material catches fire and sustains combustion. Factors that influence flammability include the presence of flammable gases, liquids, or solids in the substance.
Flammable solids are substances that can ignite easily and sustain combustion, such as wood, paper, or some metals like magnesium. These materials can pose a fire hazard and need to be handled and stored carefully to prevent accidental fires.
When butter is heated, it melts and undergoes a process known as clarification, where the milk solids separate from the fat. As it continues to heat, the milk solids may brown and give the butter a nutty flavor. However, if heated for too long, the milk solids can burn and give the butter a burnt or bitter taste.
Applying heat to grass will not cause it to melt but to burn. Glass is a silica compound that due to the addition of soda softens at about 1500 °C (2700 °F) It is not a true "melting point" since amorphous solids do not have sharp melting points like crystalline solids do.
Crystalline solids have a particular geometric organization of their atoms. Amorphous solids do not.
Not all solutes are solids.
Solids don't change their size or shape.
spongy solids are those solids which are porous...................simple and straight forward...
