Definition: Describing a material that generates an electric charge in response to a change in temperature.

Example: The pyroelectric sensor detects changes in heat and converts them into electrical signals.

Definition: A material that generates an electric charge in response to a change in temperature.

Example: The scientist studied the properties of a pyroelectric material for use in sensors.

Definition: The production of electric charge in certain materials when they are heated or cooled.

Example: Pyroelectricity is used in some sensors to detect changes in temperature.

Definition: A toxic white crystalline substance used in photography and to treat some skin conditions.

Example: Pyrogallol is often used as a developer in black and white photography.

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: A soft mineral that is black or dark gray and is mainly made of manganese dioxide, commonly used as an ore for manganese.

Example: Pyrolusite is often found in sedimentary rocks and is a key source of manganese for industrial use.

Definition: A substance that is produced when organic material is broken down by heat in the absence of oxygen.

Example: The pyrolysate from the process can be used as a fuel or chemical feedstock.

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.
