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.
