Who was the first scientist to discover crystals?

Answers

There is no actual documentation of the first person who discovered crystals as they have been around since the formation of the Earth. but, Agust Bravais was one of the very first cryptologists. Although this is the case, the very first crystals are said to be discovered deep within the caves of Africa. Nicolas Steno first discovered how quartz crystals were formed.

What scientists do that is the basis for their investigations

Answers

The basis of any scientific investigation is a hypothesis and a research question. These guide your research and help you focus on an area that is narrow enough to study for meaningful results. The research question helps quantify how you are going to study the hypothesis.

Elements and compounds are two types of what

Answers

In the given question, elements and compounds are two types of pure substances.

A pure substance is a substance that is made up of only one type of particle, either an atom or a molecule.

An element is a pure substance that is made up of only one type of atom. Elements cannot be broken down into simpler substances by chemical means. There are 118 known elements, each with its own unique properties.

A compound is a pure substance that is made up of two or more different types of atoms that are chemically bonded together in a fixed ratio. Compounds can be broken down into simpler substances by chemical means, such as by heating or reacting with other chemicals.

Therefore, pure substances are classified into two types: elements and compounds.

Elements and compounds are two types of substances ( I think). An element is any material made up of one type of atom- there could be multiples of this atom though for example oxygen which has a formula of 02. A compound is a substance made up of more than one type of atom for example H2OHope this helped! :)

What happens when you mix table salt with glucose?

Answers

the salt will dissolve with the water but the glucose aka sugar will NOT!

Aside from the responses you will get when you break up glucose in water, which are for the most part reversible when you solidify the glucose, and the responses when you disintegrate salt in water (arrangement of a water atom "coat" otherwise known as intricate around the sodium particle), there will be no response amongst glucose and salt.

Dissolvability of either compound will be lessened to some degree by the nearness of the other compound. The expansion of salt to an over-soaked glucose arrangement may begin a crystallization procedure, yet any over-immersed sugar arrangements are difficult to solidify. Take a gander at breakfast sirup or nectar for an ordinary occurrance.

When you turn on a lamp electric energy changes to?

Answers

im pretty sure it turns into thermal energy

the answer to this question is thermal energy because when you turn on your lamp it changes from electric energy to thermal energy we all know this because it is easy to see what happens when it changes.

A group of students performed an experiment to prove the law of conservation of energy. In the experiment, a flask containing water at room temperature was shaken vigorously for a few minutes. The table shows a partial record of the temperature of the water before and after shaking.Experimental Record Temperature Before Shaking 20 °C After Shaking Unknown What best predicts the unknown temperature? (3 points) a. Less than 20 °C because the total energy of the system after shaking is lower b. Greater than 20 °C because the total energy of the system after shaking is higher c. Less than 20 °C, because the mechanical energy from shaking transforms to thermal energy d. Greater than 20 °C, because the mechanical energy from shaking transforms to thermal energy
