What property of water helps cells maintain a constant temperature even when chemical reactions release energy?
The high specific heat capacity of water allows it to absorb a large amount of heat before its temperature significantly increases. This property helps cells maintain a stable temperature by absorbing excess heat produced during chemical reactions, which prevents sudden changes in temperature that could harm the cell's function.
Does pka changes with temperature?
pKa (dissociation constant) is variable with temperature.
What is the regulation of body temperature?
The part of the body that regulates our core body temperature is the region of the brain called the hypothalamus. It monitors the temperature of the blood that passes through it, and orders any physiological changes that are required to maintain a constant 37oC.
Is the rate constant dependent on temperature?
Yes, the rate constant of a reaction is typically dependent on temperature. As temperature increases, the rate constant usually increases as well. This relationship is described by the Arrhenius equation, which shows how the rate constant changes with temperature.
What usually happens in general for a gas at a constant volume?
The gas volume become constant when the pressure is increased to a point that makes the distance between the gas molecules equal to zero at this point no more increase of temperature with pressure is observed. Or if the pressure and temperature are kept constant within a system then the volume can also be constant as long as you are able to maintain the pressure and temperature at constant level.
What is homeostasis What?
Homeostasis is the maintenance of a constant internal environment in organisms even when there are external changes. For example, the body is able to maintain its same temperature of 98.6 even when it is really cold.
What is the term used to describe the constant temperature at which a pure liquid changes to vapour?
Boiling point
What is maintaining a relatively constant internal body temperature an example of?
Maintaining a relatively constant internal body temperature is an example of homeostasis. Homeostasis refers to the processes by which biological systems regulate their internal environment to maintain stable, constant conditions despite external changes. This regulation is crucial for optimal functioning of enzymes and metabolic processes within the body.
Specific rate constant?
specific rate constant is an experimentally determined proportionality constant which is different for different reactions and changes only with temperature.
Define a specific rate constant?
The specific rate constant a proportionally determined constant that is usually different for various reactions with changes in temperature.
What is the process of maintaining a relatively constant internal environment despite changes in the external environment despite changes in the external environment is called?
Homeostasis, which is the maintenance of the conditions in the cell or within the body that maintain life, despite changes that may be occurring on the outside of the body. Such as temperature. The body will maintain a internal temperature of approx. 98*6 even if it is 108 degrees or -20 below outside the body.
What happens to the speed of a wave if the medium temperature and pressure do not changes?
remains constant
