  2. Heat meter - Wikipedia

    en.wikipedia.org/wiki/Heat_meter

    A heat meter, thermal energy meter or energy meter is a device which measures thermal energy provided by a source or delivered to a sink, by measuring the flow rate of the heat transfer fluid and the change in its temperature between the outflow and return legs of the system.

  3. Vacuum flask - Wikipedia

    en.wikipedia.org/wiki/Vacuum_flask

    A vacuum flask (also known as a Dewar flask, Dewar bottle or thermos) is an insulating storage vessel that slows the speed at which its contents change in temperature. It greatly lengthens the time over which its contents remain hotter or cooler than the flask's surroundings by trying to be as adiabatic as possible.

  4. Thermal bag - Wikipedia

    en.wikipedia.org/wiki/Thermal_bag

    A thermal bag is a type of thermally insulated shipping container in the form of a bag which can be carried, usually made of thermally insulating materials and sometimes a refrigerant gel. It is used to help maintain the temperature of its contents, keeping cold items cold, and hot items hot.

    In fact, this equation is more than a phenomenological equation, it gives an operational, or experimental, definition of temperature. A thermometer is a tool that measures temperature - a primitive thermometer would simply be a small container of an ideal gas, that was allowed to expand against atmospheric pressure.

  7. Calorimeter - Wikipedia

    en.wikipedia.org/wiki/Calorimeter

    Energy is released by the combustion and heat flow from this crosses the stainless steel wall, thus raising the temperature of the steel bomb, its contents, and the surrounding water jacket. The temperature change in the water is then accurately measured with a thermometer.

  8. Vacuum packing - Wikipedia

    en.wikipedia.org/wiki/Vacuum_packing

    When foods are frozen without preparation, freezer burn can occur. [citation needed] It happens when the surface of the food is dehydrated, and this leads to a dried and leathery appearance. Freezer burn also changes the flavor and texture of foods. Vacuum packing reduces freezer burn by preventing the food from exposure to the cold, dry air.

  9. Thermometer - Wikipedia

    en.wikipedia.org/wiki/Thermometer

    Mercury thermometer (mercury-in-glass thermometer) for measurement of room temperature. [1]A thermometer is a device that measures temperature (the hotness or coldness of an object) or temperature gradient (the rates of change of temperature in space).
