Definition: The study of the physical processes involving the emission of electrons from heated materials.

Example: Thermionics plays a crucial role in the development of vacuum tubes and other electronic devices.

Definition: A type of electrical component that changes its resistance based on temperature, often used in temperature sensing and control.

Example: The thermistor helped regulate the temperature in the heating system.

Definition: A chemical mixture made of aluminum and iron oxide that produces a lot of heat when ignited, often used in welding and explosives.

Example: The workers used thermite to weld the metal parts together.

Definition: Related to the study of the relationship between heat and chemical reactions.

Example: The thermochemical properties of the substance were analyzed during the experiment.

Definition: A person who studies or works in the field of thermochemistry, which is the branch of chemistry that deals with the heat involved in chemical reactions.

Example: The thermochemist conducted experiments to understand the energy changes during the reaction.

Definition: This is a field of chemistry that studies how heat is involved in chemical reactions and changes in physical states.

Example: Thermochemistry helps scientists understand how much heat is released or absorbed during a reaction.

Definition: A layer in a body of water that separates warmer water on top from colder water below, where the temperature changes quickly as you go deeper.

Example: The fish prefer to stay in the thermocline where the temperature is just right for them.

Definition: A device that measures temperature by using two different metals joined together, which creates a voltage that indicates the temperature difference.

Example: The engineer used a thermocouple to monitor the temperature of the furnace.

Definition: Able to live or remain active at high temperatures, particularly during processes like pasteurization.

Example: Some bacteria are thermoduric, meaning they can survive the heat during pasteurization.

Definition: Relating to the branch of physics that deals with heat and temperature and their relation to energy and work.

Example: The thermodynamic properties of the gas were analyzed in the experiment.
