Definition: A type of organic compound that has a single ring structure and contains nitrogen. It is important in biology as it forms part of DNA and RNA, specifically in the bases uracil, cytosine, and thymine.

Example: Pyrimidine is essential for the synthesis of nucleic acids in living organisms.

Definition: Relating to or containing a type of mineral known as pyrite, which is often called fool's gold due to its metallic luster and pale brass-yellow hue.

Example: The geologist examined the pyritic rocks for signs of gold deposits.

Definition: Relating to or made up of rock fragments that come from volcanic eruptions.

Example: The pyroclastic flow destroyed everything in its path during the volcanic eruption.

Definition: A substance that causes an increase in body temperature, leading to fever.

Example: The doctor explained that a pyrogen can trigger a fever in response to infection.

Definition: Relating to the generation of heat or fever, often associated with the production of heat in a physical or biological context.

Example: The pyrogenic response in the body can lead to an increase in temperature during an infection.

Definition: The scientific study of how heat or flames affect materials, especially in relation to explosives and chemical reactions.

Example: Pyrology is essential for understanding how different materials react to high temperatures.

Definition: To break down or change a material by applying heat without oxygen, causing it to decompose.

Example: The waste was pyrolysed to convert it into useful energy.

Definition: The process of breaking down a substance through the application of heat, resulting in a chemical change.

Example: Pyrolysis is often used to convert organic materials into biofuels.

Definition: In a way that involves the chemical decomposition of organic materials through the application of heat in the absence of oxygen.

Example: The waste was treated pyrolytically to reduce its volume and toxicity.

Definition: To heat a substance in the absence of oxygen to cause it to break down chemically.

Example: The researchers decided to pyrolyze the organic waste to produce biochar.
