Because we are warm blooded, ectothermic are cold blooded and can controll thier body temp. Therefore they have a lower BMR ( Basal metabolic rate )
No, spiders are not endothermic; they are ectothermic organisms. This means that they rely on external environmental sources to regulate their body temperature rather than generating their own heat internally. As a result, their metabolic rate and activity levels are influenced by the temperature of their surroundings.
An endothermic reaction can be spontaneous at room temperature if the increase in entropy of the system is large enough to overcome the energy input required for the reaction. This can happen if the products of the reaction have higher entropy than the reactants. As a result, the overall change in free energy can be negative even though the reaction is endothermic.
Endothermic reactions are the type of chemical changes that absorb heat energy from their surroundings. In these reactions, the products have higher energy content than the reactants, resulting in a decrease in temperature in the surrounding environment.
This question is oddly worded, but I am assuming that the author means to ask "in chemical equations for endothermic reactions, is the change in energy (delta H) positive or negative?". For endothermic reactions, heat is absorbed during the reaction, so the energy of the products is higher than the energy of the reactants. Since dH = H(products) - H(reactants). Therefore, dH is positive.
Although it is hard to predict if a reaction will be exothermic or endothermic, there are many factors that can be considered when trying to determine it. first endothermic reactions usually employ the breaking of strong bonds, and the creation of weak bonds. While exothermic reactions usually break weak bonds and create strong bonds. Sadly these are the only ways to predict if a reaction will be endothermic or exothermic, altough there are other methods that could be used that are much more complex.
Endothermic
Kinetic energy has more energy than products.
endothermic means it is absorbing heat. the heat within the organism would be warmer than the surrounding environment over time.
In an endothermic reaction, the products have a higher heat content than the reactants. This means that energy is absorbed from the surroundings, resulting in a decrease in temperature.
In an endothermic reaction, the products have higher energy than the reactants. This means the reactants have lower energy compared to the products.
thermoregulation occurs in ectotermic & endothermic organism according to the change of ground temperature.Generally ectotermic / poikilothermic animals obtain heat from the enviroment than the metabolic rate to raise their body temperatures is bcoz,they have low metabolic rate & unable to maintain their body temperature within the narrow limits using physiological mechanism.Example of organism are non-vertabrates,fish, amphibia & reptiles.Lizard are reptiles, which we noticed that they are nocturnal.this is bcoz during day time they move to dark area / find shelter under rock in order to obtain heat energy from the surrounding or enviromemt.So they able to save energy to prey at night time.However, endothermic or homoiothermic animals rely on metabolic heat to maintain their body temperature able to maintain the body temperature by physiological mechanism.example are bird & mammal's.This is how different kind of organism maintain the body temperature according to the enviroment.
An endothermic reaction absorbs heat from its surroundings, causing a decrease in temperature. In a chemical equation, if the products have a higher energy content than the reactants, it indicates that the reaction is endothermic. This can be determined by examining the enthalpy change (∆H) of the reaction.
In an endothermic reaction, the products are generally less stable than the reactants. This is because the reaction absorbs heat from the surroundings to proceed, indicating that the products have higher potential energy than the reactants.
No, leeches are not endothermic; they are ectothermic organisms. This means that they rely on external environmental temperatures to regulate their body heat, rather than generating their own heat internally. As ectotherms, their metabolic processes and activity levels are influenced by the surrounding temperature.
No, spiders are not endothermic; they are ectothermic organisms. This means that they rely on external environmental sources to regulate their body temperature rather than generating their own heat internally. As a result, their metabolic rate and activity levels are influenced by the temperature of their surroundings.
Endothermic reaction: In an endothermic reaction, the products are higher in energy than the reactants. Therefore, the change in enthalpy is positive, and heat is absorbed from the surroundings by the reaction therefore enthalpy change show positive sign in a endothermic reaction..
No, crayfish are not endothermic; they are ectothermic organisms. This means that they rely on external environmental conditions to regulate their body temperature, rather than generating heat internally. As a result, their metabolic processes and activity levels can be significantly influenced by the temperature of their surrounding habitat.
