Heating randomizes the alignment of the atoms.
At a specific high temperature, called Curie point, the ferromagnetism disappear.
By heating the homogenate. proteins are innactivated by heat and enzyme activity is lost
Direct heating can be thermodynamically wasteful because a significant amount of heat is lost to the surroundings during the heating process. This leads to lower efficiency in converting energy to heat, as the heat is not efficiently retained or transferred to the substance being heated. This wastage results in higher energy consumption and costs.
The amount of water loss from cuso4·5h2o can be determined by measuring the weight of the crucible and compound before and after heating. The initial weight represents the compound with water, and the final weight after heating will show the loss of water as the difference in weight. By subtracting the initial weight from the final weight, the amount of water lost can be calculated.
Up to cca. 480 0C iron(II) sulfate lost crystallization water; after this temprature the sulfate is decomposed in iron oxide and sulfur oxide.
it is not feromagnetic
they are iron nickel cobalt and manganese
It is lost in heating the resistive material of the rheostat.
Maxwell's equations ... electro-magnetism.
Ferromagnetism
Yes, nickel is ferromagnetic. It exhibits ferromagnetism due to its atomic structure, specifically the alignment of its magnetic moments in domains that can be easily magnetized in the presence of an external magnetic field.
1/3 rd lost
By weighing the sample before and after heating to dehydration.
Cobalt, iron, and nickel exhibit ferromagnetism at reasonable temperatures. Check the Wikipedia article on "ferromagnetism", for additional materials that exhibit ferromagnetism - some of them are compounds, and some only exhibit ferromagnetism at temperatures that are too low for many practical uses (for example, Dysprosium requires a temperature below 88 kelvin).
Obtain ASE certification in heating and AC systems.
At a specific high temperature, called Curie point, the ferromagnetism disappear.
