Science Experiments

Temperature can not be used to identify a type of matter

True

Slate is not a specific mineral, and thus has no particular chemical composition. It is a sedimentary rock, lightly metamorphosed, and formed from fine grained parent material. It may include fine fossils.

a variable factor is anything in your experiment that can change. not like a control factor, which is kept constant through the whole experiment.

A wooden splint that is used in an experiment is set on fire and held over a container of gas. The color of flame and amount of popping that the woodne splint does will tell you what type of gas is in the container.

They test for different gaseous presences. Usually for oxygen, carbon dioxide or hydrogen.

Salt freezes slower (i.e. at a lower temperature) than fresh water. Generally the greater the level of dissolved substances, the harder it is for ice crystals to form, so the greater the level of cooling required. Completely saturated saltwater freezes at -6°F / -21.1° C. == ==

what are the two major groups of minerals

Jamie Craig's cool as! So's Craig :) lol

The LHC is for the most part absolutely safe. No need to worry about it causing Doomsday anytime soon. Though they say it could cause a micro black hole that would only exist for one-millionth of a second. Possibly it can create Antimatter that reacts to Normal matter. I also have read that it could create particles called Strangelets which is matter that will turn what ever it touches to its self and so on until all matter around it is a form of its self. Luckily for us the possible Black hole will not be around long enough to even tell (unless they are actually able to pick up the radiation it produces with a sensor and prove that it came from a subatomic black hole). Antimatter can be contained within a vacuum so it has no ability to react with normal matter; and Strangelets are only a scientific theory.

The red and green inks are uniformly distributed throughout the pan.

We would need to know exactly what graphs you want explained. A bar graph is used to show different values of two or more subjects. It uses horizontal and vertical bars that represent a different value. A line graph compares two different types of information by showing how they are similar and different. A pie chart is designed to show the difference between two separate subjects.

list some variables that can change in an experiment?

You will get an exact answer from working on the exipremement.(intead of hypotesising an answer from what you heard)

to isolate and test single variables

Liquids are usually measured in Liters (l) which are just slightly larger than a US quart.

Smaller quantities are often measured in milliliters (ml).

Note, many of the units in the metric system have other equivalent measurements. So, a liter is equivalent to a cubic decimeter, and a liter of water will weigh 1 kg (at 3.98°C, 1 ATM).

1 ml of water weights 1 gram (gm), and occupies 1 cubic centimeter (cc or cm3).

To be true a scientific principle must be theoretically explained and experimentally (and statistically) checked to be correct and repeatable.

I dont know u tell me
