Scientific Method

Pure water is evaporated faster.

A constant.

It is important to ensure that only one factor changes in an experiment (called the independent variable). All other factors need to remain constant.

graphical method is applicable only for solving an LPP having two variables in its constraints , but if more than two variables are used, then it is not possible to use graphical method. In those cases, simplex method helps to solve such problem.

In simple, in graphical method is used when the constraints contain two variables only.

But simplex method can be used to solve constraints having more than two variables.

Here is a possible comparison of a hypothesis and a theory in science:

A hypothesis is basically an educated guess, where nothing has been tested yet, whereas a theory is a hypothesis that has been tested over and over, numerous times, with the same results.

The Scientific Method is a method made by science

The scientific method can be used to provide a proof. In most cases, it cannot be disproven.

This answer makes a little sense as presented, but it's neither complete nor correct. It's generally accepted by researchers today that NOTHING can be scientifically proven to be correct. One can offer support to an hypothesis, and when a vast quantity of evidence gathered seems to do support the hypothesis, it may graduate to the level of a THEORY. That's about as close to ''proof'' as we can get. This means that stating some scientific contention is a theory is a very strong statement indeed. It means essentially that everyone in the scientific community accepts it as correct. That still doesn't mean it is correct...it simply means that all known evidence accumulated to date has demonstrated that it is.

The reason for this apparent waffling is that results that may or may not support a given hypothesis are mutable. The development of new instruments or ideas can alter results and conclusions. Over the years, this has happened many times.

There are many who believe that while science can never prove an hypothesis is right, it can be proven to be wrong. I would argue that while the idea may sometimes seem to be absolutely wrong, time and breakthrough instrumentation could alter that evidence also.

This depends very much on the conditions the mold was grown under. For instance, if we are comparing how mold grows in light versus how mold grows in the dark, our null hypothesis may be 'Mold grows more rapidly in light than in the dark'. An essential factor to consider when setting a hypothesis is to ensure that it is testable (i.e. we are able to test the validity of the hypothesis and choose to accept/refute it). Hence, a statement such as 'Mold grows better in light than in the dark' is not testable (and would thus not qualify as a hypothesis), since there is no scientific definition of what is being implied by the term 'better'.

which of these is always part of scientific method

hydrogen gas is H2

When H2 reacts with oxygen and fire (energy)

It is combustion

H2+ 02= 2(H20)

Which is water. In that state it is water vapor.

A popping noise is also made. That is water vapor racing out.

The burning splint tests, basically, is when an individual lights a splint. On lighting this splint, it should be placed near a bottle containing hydrogen gas [ H2 ]. On carrying out this action, the glowing splint may increase in size, regarding the size of the flame, that is. The Hydrogen gas, on the other hand, will make a popping sound. The intensity of the 'pop' will depend on the amount of Hydrogen gas collected in the bottle. Take care to ensure that no Hydrogen gas escapes, or is released from the bottle, until the splint is placed, at least 2 inches away from the opening of the bottle.

Tools can range from instrument of measurement like thermocouple, equipment like test tube or even a hammer for geologist, complex construction like the hardron collider to the use of knowledge like matrix operation as tools for mathematician. Tools can be invented per task of study,it is unlikely number of tools can be countable.

Though its rigorous 'rules' regarding what falls under good science, read 'science with integrity.' Namely, this is through a strong sense of empiricism via a focus on provable claims, repeatable tests, and a strong peer review system.

'Provable claims' disallows a science based on mythology, allowing only 'scientific' type ideas to enter the realm of 'good science' (this is hard to fully pin down as there may be many instances of good science that did not start with provable claims, none the less, it is considered important to have such).

'Repeatable tests' and 'peer review' ensures science is not built on false data. First, the scientist repeats their experiments until the data is strongly conclusive. Second, they send their data off to be reviewed by experts who will do their best to poke holes in it.

It is by this way that science moves from claim to test to review to theory in such a way that 'bad' science rarely finds a foothold.

it is a physical change , sublimation is a transition of a substance from the solid phase to the gas phase without passing through an intermediate liquid phase. the iodine crystals when subject to heat turns to a violet gas , and when it cools it turns back to solid form. the composition doesn't change so it n is only a physical change

Among other things, it must be based on reliable data and repeatable experimental results.
