About 75% of heat is generated in the shear zone
Because almost no heat is produced during this reaction. That is why it is often called "cold light".
Heat is produced when energy is converted, in one of many ways, from one form to another. Electric heaters convert electricity to heat; rubbing your hands together (friction) converts kinetic energy to heat, fire (exothermic reactions) convert chemical energy to heat, and so on.
"friction"
the right side
energy used for the machine will get lost as heat .machine parts will get worn out.
Converts to heat
If the reaction is exothermic then heat is produced.
heat is produced
Annealing.
heat
Respiration produce ATP mainly.CO2,H2O and heat also produced.
There are N in fuel. In very high heat N is oxidized into its maximum
Respiration produce ATP mainly.CO2,H2O and heat also produced.
In machining operations, a live center rotates with the workpiece, reducing friction and heat. A dead center does not rotate and can cause more friction and heat buildup.
The unit of measurement used to measure the amount of heat produced during metabolism is kilocalorie (kcal). This unit is commonly used to quantify the energy content of food as well.
Well, honey, when you're breaking down those macronutrients during respiration, your body is like a little furnace, producing heat as a byproduct. You can measure this heat production using a calorimeter, which basically tells you how much energy is being released during the process. So, yeah, next time someone asks you why you're hot stuff, you can tell them it's just your cells working hard during respiration.
The free energy (delta G) is the measure of the amount of energy produced or consumed in a reaction. Enthalpy (delta H) is a measure of the amount of heat produced or consumed in a reaction. These two quantities can sometimes be the same. When they are not, the other missing component where heat can be consumed or produced is work.
