How heat is produced
WebHow is heat produced? Heat can be produced in many ways such as burning, rubbing, and mixing one substance with another. Heat can move from one object to another by conduction. How is the heat produced by an electric current related to resistance? – Additional Questions Why heat is produced in wires when current flows? WebStep 1: Reaction of acetylene with oxygen Note that the enthalpy of combustion of acetylene (∆H) = -1301.1 kJ/mol. The equation representing the burning of 1mol of acetylene is: C2H2(g) + O2 --> CO2 (g) + H2O (l) Step 2: Calculation of heat Enthalpy of combustion of acetylene is -1301.1 kJ/mol.

WebAccording to the equation, 2 moles of nitromethane on combustion gives 1418 kJ of heat. Thus, the heat produced by the combustion of 91.15 moles of nitromethane: Heat produced=1418kJ/2moles*91.15= 129250.7 J Need a fast expert's response?

Heats of combustion are usually determined by burning a known amount of the material in a bomb calorimeter with an excess of oxygen. By measuring the temperature change, the heat of combustion can be determined. A 1.55 gram sample of ethanol is burned and produced a temperature increase of 55oC in 200 …
Web24 jan. 2024 · 1. If the amount of current flowing through a resistor is doubled, then the heat produced will become four times. 2. If the resistance of the conductor is doubled, then the heat produced will also get doubled. Similarly, the heat produced in the conductor reduces to half when the resistance of the conductor becomes half. 3. Web14 dec. 2015 · The simple answer is that the sun, like all stars, is able to create energy because it is essentially a massive fusion reaction.

They produce heat because the surfaces on small scales are rough like canyons rather than flat like the ocean. As these rough surfaces come into contact with each other they repel. When two atoms are brought very close together they store potential energy. When they move apart that energy becomes kinetic.
Web22 jan. 2024 · The most common technique is to extract hydrogen from water, which is two parts hydrogen and one part oxygen (hence H2O). Doing this is fairly simple. You can use heat and chemical reactions to release hydrogen from organic materials such as fossil fuels. But this is enormously polluting.
