Yes. A theory is a proposition that suggests that with all that is known at present a situation is likely to be or exist in a certain way. This can change as the evidence surrounding the proposition changes. Even thing that were once considered laws of nature and physics have been known to change as a result of new information coming to light.

What best described a theory?
a) an idea that has never been proven wrong
What do people believe about the phlogiston theory?
The phlogiston theory, which suggested that all combustible materials contained a substance called phlogiston that was released during combustion, was once widely accepted. However, it has since been discredited with the advancement of modern chemistry and the discovery of oxygen's role in combustion. Today, the phlogiston theory is considered a historical scientific misconception.
What evidence is there to prove phlogiston theory of burning was correct?
The phlogiston theory has been debunked by the discovery of oxygen. When materials burn, they combine with oxygen, not phlogiston as believed in the theory. The understanding of combustion and oxidation provided by oxygen led to the rejection of the phlogiston theory.
Is a burning candle a reversible or non reversible change?
Burning a candle is a non-reversible change because once the wax is melted and the wick is burnt, it cannot be undone to return the candle to its original state. The chemical composition of the wax and wick is changed permanently.
Is burnt toast irreversible or reversible?
Burning is an irreversible change.
Why is a hypothesis important to a scientist?
Once a hypothesis have been confirmed through numerous experimental tests, it can then become a theory. Theories are much more powerful and expansive in scope than hypotheses. Once a theory has been established, it is the role of scientist to try and disprove a theory rather than to try to reinforce its proof.
When a theory has been established a it cannot change b it must become law c it may be altered or changed or d it becomes accepted scientific principle?
Once a theory is established, it both becomes accepted scientific principle and may be altered or changed at a later point (normally upon discovery of new evidence or through revaluation of existing evidence).
Under what conditions can a scientific model or theory change?
A scientific model can change if new evidence is found. If the new evidence that has been found contradicts the model or theory then a scientific model or theory can change.
Why independent factor is taken on x-axis in a graph?
It is an established custom. There is no mathematical reason why it could not have been the other way round. But once established as a "standard" changing it can cause confusion and also some problems.It is an established custom.

How does a scientific theory from a hypothesis?
once a hypothesis has been supported in repeated experiments, scientists can begin to develop a theory.
Does a theory have to be true all the time?
Not at all. That it hasn't been proven is what makes it a theory. Once proven, it becomes a law.
How many times has wolves been relegated from the premier league since established?
Once.
What is the theory of climate change?
There is no"theory of climate change" as it has been demonstrated and observed by trained scientists for several decades.if there is a theory it is from the climate change deniers who insist that the process is "all natural" and will reduce itself without human effort.
How can a scientific theory change?
they can change by summarizing a hypothesis or group of hypotheses that have been supported with repeat testing.
Youve been noticing hair in new places yet no voice change is this puberty?
Naturally not all changes happen at once or in an established order. If you are seeing hair in new places then you are most likely entering puberty, the voice change will come later on
What do we call a theory that has successfully been tested repeatedly and has stood the test of time?
A theory that has been successfully tested repeatedly and has stood the test of time is generally referred to as a well-established or robust theory. This term indicates that the theory has consistently shown to be valid and reliable across multiple experiments and observations in various conditions.
Is a hypothesis less supported than a theory?
Yes, a hypothesis is a proposed explanation that has not been extensively tested or confirmed, while a theory is a well-supported explanation that has been validated through repeated testing and observation. In scientific terms, a theory is considered more established and supported than a hypothesis.
