A Junkers Calorimeter is a device for determining the heating capacity of a gas - that is, how many joules one can get by burning a set volume of that gas. It's usually [natural] gas from the mains, but could be any flammable gas.
The device is essentially a Bunsen burner with a cooling jacket. The jacket is cylindrical in shape, about 80cm tall, with water running through it. The burner sits inside the cylinder. The calorimeter allows the user to measure the temperature of water flowing in and flowing out. Once steady-state is reached, with those two temperatures steady, the water flowing through is collected for a specified period of time. Measuring the mass of the water and the temperature rise in the water, the operator can calculate the number of joules which went into the water to heat it. There is a flow meter on the fuel gas, so the operator can also calculate the volume of gas that was burned in the same time period. The amount of energy, in J, available per litre of gas can then be calculated.
A Junkers calorimeter is a flow calorimeter, with heat transfer happening continuously, as opposed to a batch calorimeter.
The design dates back to the late 1800s.
what role did prussian junkers play in prussian society NEW RESPONDENT The Junkers were the descendants of the Teutonic Knights, who in the Middle-age times dominated Prussia. They were deprived of most of their political power in the seventeenth and eighteens century by the Hohenzollern kings. But nonetheless they were able to acquire vast land estates, retaining local administrative authority, dominating the court , army and civil service. They also were holding most of the ministries and public offices. The great economic growth, outcome of the industrial revolution, gave birth to a new class of manufacturers, merchants and professionals, who tried to force their way beside throne and Junkers. They were rebuffed by the strong alliance between the king and the reactionary Junkers' élite, whose prominent role was to last until 1918.

Junkers
Junkers were influential landowners in Germany and Prussia under the German Empire and the Weimar Republic. Junker comes from the Middle High German word, Juncherre, which means 'young nobleman.'
Bomb calorimeter is the apparatus used to find the change in internal energy with respect to heat capacity at constant pressure.
yes it can
Yes energy can be measured directly with a calorimeter. The calorimeter will measure the temperature as it changes in a reaction.
The population of Junkers is 40,000.
Junkers was created in 1895.
Hugo Junkers was born on February 3, 1859.
Hugo Junkers was born on February 3, 1859.
The noble landowners of Prussia were known as Junkers.
bomb calorimeter is heat combustion
A calorimeter is used to keep heat contained in a single place as the calorimeter absorbs very little heat and the amount it absorbs can easily be calculated. To use the calorimeter heat the liquid you want (or cool) and place it in the calorimeter cup and put that in the calorimeter and place the lid on top and the thermometer in the thermometer's hole. There you go. Simple as that. A calorimeter is used to keep heat contained in a single place as the calorimeter absorbs very little heat and the amount it absorbs can easily be calculated.
