To record temperature using such an instrument

plural of thermonuclear weapon

plural of thermodynamic temperature

Thermodynamics that studies a thermodynamic system as an undivided whole, described by macrostate variables such as volume, pressure and temperature, instead of considering the thermodynamic system as an ensemble of moving molecules.

Thermodynamics that studies a thermodynamic system as an ensemble of moving molecules, considering the macroscopic temperature as an average kinetic energy of the microscopic molecules.

activated by heat

(physics) A localized physical system consisting of interacting components, called degrees of freedom

(physics) A set of values (state variables) that together constitute a complete specification of the thermodynamic properties of a system.

(measuring instrument) A device consisting principally of an alcohol thermometer, used to measure air cooling power and, indirectly, small wind speeds in circulating air, by measuring the time taken for the temperature of the bulb of alcohol to make a specified drop (100° to 95°F).

A thermometer used to measure the temperature of heated sugar syrup during the preparation of caramel and similar products.
