What happens when a Bose-Einstein condensate forms?
A. A large atom is split into many smaller atoms temporarily.
B. The atoms of the solid condense into one large superatom.
C. It causes all matter touching it to condense into a liquid.
D. The electrons separate from the nuclei forming a mass of unbound positive and negative charges.
Answer:
the answer would be B
Explanation:
The atoms of the solid condense into one large superatom. Hence, option B is correct.
What are atoms?An atom contains a central nucleus surrounded by one or more electrons.
Bose-Einstein condensation occurs at a temperature very close to absolute zero i.e 273.15 degrees centigrade. Under such conditions, a large quantity of Boson occupies the lowest quantum state, at which point microscopic quantum phenomena become apparent macroscopically. A BEC is formed by cooling a gas of extremely low density about one hundred thousandth the density of normal air, to ultra-low temperature.
Hence, option B is correct.

What is a measuring cylinder?A Measuring cylinder, a graduated cylinder, a cylinder measuring, or a mixing cylinder is a part of various laboratory materials that are used for the measurement of the volume of liquids, chemicals, or solutions during laboratory work.
Graduated cylinders have more precise and accurate measurements than the common volumetric flasks and beakers used in the laboratory. These are of various volumes ranging from small to big.
These graduated cylinders are also used for the determination of displacement. It is a measurement of the change in a volume of water when some additional materials are added to it.
This means that a graduated cylinder can be used for the determination of solid materials by taking the difference between the initial volume of water and the new volume of water.
Therefore, in this case, the mark represents a volume of 25ml.

How does a scientist test their hypothesis?
Answer:
Conducting experiments and using the scientific method.
Explanation:
Scientists (and other people) test hypotheses by conducting experiments. The purpose of an experiment is to determine whether observations of the real world agree with or conflict with the predictions derived from a hypothesis. If they agree, confidence in the hypothesis increases; otherwise, it decreases.

Answer:
[tex]V_{1} = \frac{P_{2}V_{2}T_{1}}{P_{1}T_{2}}[/tex]Explanation:
[tex]\frac{P_{1} V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}}[/tex]
First of all cross multiply
That's
[tex]P_{1}V_{1}T_{2} = P_{2}V_{2}T_{1}[/tex]
Next divide both sides by [tex]P_{1}T_{2}[/tex] in order to isolate [tex]V_{1}[/tex]
We have
[tex]\frac{P_{1}V_{1}T_{2}}{P_{1}T_{2}} = \frac{P_{2}V_{2}T_{1}}{P_{1}T_{2}}[/tex]
We have the final answer as
[tex]V_{1} = \frac{P_{2}V_{2}T_{1}}{P_{1}T_{2}}[/tex]

Molding a shape from soft, malleable material (clay or plaster) or constructing a shape from harder material (such as metal or paper). Molding is what a child does with Play-Doh or origami.
Complete question is;
Molding a shape from soft, malleable material (clay or plaster) or constructing a shape from harder material (such as metal or paper) is called what?
Molding is what a child does with Play-Doh or origami
Answer:
Modeling
Explanation:
In chemistry, we have a branch called modeling chemistry. In modeling, we organize together a series of models instead of a collection of topics. In this approach, we will begin with a phenomena that can be readily observed and are gradually develop the simplest model of matter that helps us make sense of our observations.
Now in the question, we are Molding a shape from soft, malleable materials like clay/plaster or constructing from harder materials like metal/paper. This means that we are organizing a series of models from either soft & malleable or harder materials to produce a simple model shape.
Thus, this is simply modeling.

water is 11.19% hydrogen and 88.1% oxygen by mass. Lake superior contains about 1.2x10 kg of water. what mass of hydrogen is contained in lake superior
Answer:
mass of hydrogen in lake = 11.19% of 12
= 1.3428
check if question is correct or not
Explanation:
Water is 11.19% hydrogen and 88.1% oxygen by mass. Lake superior contains about 1.2x10 kg of water the mass of hydrogen is 1.32 kg
What is mass?Mass is defined as a unit of measurement that describes the amount of matter that makeup an object.
It can also be defined as quantitative measures of inertia, fundamental properties of all matter. It is a dimensionless quantity.
As given 11.19% hydrogen is present in 1.2 x 10 kg
So, the mass of hydrogen = 11.198 % of 1.2 x 10 kg
= 11.19 / 100 x 12
= 1.32 kg
Thus, water is 11.19% hydrogen and 88.1% oxygen by mass. Lake superior contains about 1.2x10 kg of water the mass of hydrogen is 1.32 kg.

Explanation:
hope it help ^_^
Mass is the most basic property of matter and it is one of the fundamental quantities. Mass is defined as the amount of matter present in a body. The SI unit of mass is the kilogram (kg). The formula of mass can be written as:
Mass = Density × Volume
The mass of a body is constant; it doesn’t change at any time. Only in certain extreme cases when a huge amount of energy is given or taken from a body, the mass may be impacted. For example, in a nuclear reaction, a tiny amount of matter is converted into a huge amount of energy, this reduces the mass of the substance.
There are various units for calculating mass, like, kilograms, grams, lbs, pounds, etc., but the SI unit of mass is "kilograms" or kg. Every unit of mass can be converted to other units by using a proper conversion formula without affecting the meaning and essence of the quantity to be measured.

Which describes a property of water that allows plants to transfer it from their roots to their leaves?
O Water exhibits weak adhesion and cohesion, which allows capillary action to occur.
O Water exhibits strong adhesion and cohesion, which allows capillary action to occur.
Water has low surface tension, which prevents capillary action from occurring.
Water has high surface tension, which prevents capillary action from occurring.
Answer:
B water exhibits weak adhesion and cohesion which allows capillary action to occur.
Explanation:
took the test
Water exhibits strong adhesion and cohesion, which allows capillary action to occur.
What property of water allows it to move through a plant?The cohesive properties of water (hydrogen bonding between adjacent water molecules) allow the column of water to be 'pulled' up through the plant as water molecules are evaporating at the surfaces of leaf cells. This process has been termed the Cohesion Theory of Sap Ascent in plants.
What are adhesion and cohesion?Cohesion and adhesion are two water properties that describe how water molecules interact with each other. and how water molecules interact with other things like leaves or even you. Cohesion means that water likes to stick to itself and adhesion means that water likes to stick to other things.
