What else can I help you with?
What is the name of the theory that states species evolve during short periods of rapid change?
It is called Punctuated Equilibrium. Some Evolutionary apologists, notably Richard Dawkins, have down played this aspect of Neo-Darwinistic theory.
Which of the following correctly matches the equilibrium receptor to the type of equilibrium it monitors?
maculae/static equilibrium
What theory states that species stay the same for a long time and then change quickly because of environmental changes?
Good ol' punctuated equilibrium.
What is a model of evolution in which short periods of drastic changes in species are separated by long periods of little or no change?
Punctuated Equilibrium, I believe is the answer.
How does the punctuated equilibrium model of evolution states that evolution occurs rapidly?
Gradualism is the theory that evolution occurs slowly and consistently along periods of time. On the other hand, punctuated equilibrium is the theory that evolution does not occurs for long periods of time and then suddenly evolves rapidly in a small short period of time.
What is difference between physical and chemical balance?
The difference is that chemical equilibrium is the equilibrium of products and reactants in a reaction while physical equilibrium is the equilibrium of the physical states of the same substance.
What does Le Chtelier's principle state?
Le Chatelier's principle states that a system at equilibrium will respond to a disturbance by shifting its equilibrium position in a way that minimizes the effect of the disturbance. This means if you change the conditions of a reaction at equilibrium, the system will adjust to counteract that change and establish a new equilibrium.
What is the LeChatlier?
The Chatelier's Principle states that when a dynamic equilibrium is disturbed by changing conditions then the position of equilibrium shifts to counteract the change to reestablish equilibrium. A chemical reaction is at equilibrium and experiences a change in pressure, temperature, or concentration of products , equilibrium will shift in opposite directions to offset change.
In what system can reactants exist in different physical states?
heterogenous equilibrium
What do the lines on phase diagram represent?
equilibrium between two states
When a change is introduced to a system in equilibrium the equilibrium shifts in the direction that relieves the stress on the system is known as?
Le Chatelier's Principle. This principle states that when a system in equilibrium is subjected to a change, it will adjust to counteract the change and restore equilibrium.
The law of thermodynamics states that two systems that are each in thermal equilibrium with a third system are in thermal equilibrium with each other?
The zeroth law of thermodynamics states that if two systems are in thermal equilibrium with a third system, then they are in thermal equilibrium with each other. This law helps define temperature and sets the basis for building thermometers. It ensures that a consistent temperature scale can be established.
What is a characteristic of chemical equilibrium but not physical equilibrium?
In chemical equilibrium, the concentrations of reactants and products remain constant over time, whereas in physical equilibrium, there is a balance between two opposing physical processes such as melting and freezing. Chemical equilibrium involves the establishment of equilibrium between reactants and products in a reversible reaction, while physical equilibrium involves the balance between different physical states of matter.
Is the temperature at which a liquid and solid states of a substance are in equilibrium is the same as the melting point and freezing point of the substance?
Yes, the temperature at which the liquid and solid states of a substance are in equilibrium is the same as the melting point and freezing point of the substance. This is because at this temperature, the rate of melting is equal to the rate of freezing, resulting in a dynamic equilibrium between the two states.
In a heterogeneous equilibrium system the reactants and products exist in what?
Different physical states
What does Le Châtelier's principle state?
A reaction at equilibrium will respond to balance a change. :D
What is consumer equilibrium?
consumer equilibrium states that consumer maximise his utility with the given income and with the given price or when a consumer getting maximum satisfaction with available resources then he will be in a state of equilibrium.
