endothermal การใช้

The reaction energy ( the " Q-value " ) is positive for exothermal reactions and negative for endothermal reactions.
You can measure the total human electrochemical waste heat quite easily, it's basically what raises endothermal body temperature above ambient temperature, but I won't go into the details . talk ) 21 : 00, 23 March 2015 ( UTC)
But in the 1970s, Dr . John Ostrom of Yale University and other scientists theorized that at least some dinosaurs were truly endothermal : capable of maintaining constant temperature by adjusting their metabolisms to warm or cool their own blood, compensating automatically for environmental temperature changes.
