established way to compare the density of a substance with the density of water

presuppositions lead to absolute truths

any measurable aspect of something

The J-Tube, inverse relationship between the volume and pressure of a confined gas

evaluates how close a measurement is to the acceptable value of the measurement

an accepted model that explains something

Created a thermometer that worked on the theory that gas pressure is proportional to its temp.

an assumption that a person makes about the world to understand it from a certain point of view

Changes of pressure on a confined fluid are exerted equally throughout the fluid and container

for a scientific theory to be acceptable, it must be both true and plausible

ions with more electrons than protons and have a negative charge

An immersed object is lifted or buoyed up by a force equal to the weight of the fluid displaced

amount of matter in an object

change in the neutrons or emitting or absorbing high energy rays or particles

God made humans to subdue the earth and have dominion over it (Genesis)

Pressure differences in an unconfined fluid causes ___________________

an inclination one has about an idea after thinking about its pros and cons

the study of the composition of substances and how they act in the presence of other substances

every model is an imperfect representation of something

the one property besides hardness that sets solids apart from the other states of matter is ___

At a given point in a body of water, the pressure is exerted equally in all directions

the amount of matter in an object

anything that is observable and measurable

Volume of a fixed amount of gas changes in the same as its absolute temp at constant pressure

The greater the height the lower the pressure, the lower the height the higher the pressure

a scientist with a secular worldview may still discover or accomplish great things in his life

Does Pascal's Principle take Newton's 3 laws into account?

Developed the law of partial pressures

Partial pressure of each gas depends only on its temp and the density of molecular mass 

has two or more substances together

Water pressure depends almost entirely on depth.  Water pressure due to depth alone is called?

which is not a state of matter

change in a substance that affects the kinds of atoms and/or the way they are bonded together

the space enclosed or occupied by an object

This scientist studied the flow of water through pipes of different sizes.

any kind of information or observation used in an investigation

a model that describes a phenomenon but doesn't or can't explain it 

are made of only one substance

The most common application of Pascal's Principle is found in the application of _____________?

the fundamental model of matter

vapor returning to a solid

deals with how matter and energy interact

Fluids flowing close to a curved surface tend to follow the shape of that surface.

a bias that a person holds to it without thinking about it, it is often unreasonable

every person is born with his or her own world view

the melting and retreat of a glacier is a physical change

the initial model to explain the phenomenon 

study of phenomena that happened in the unobserved past and that are not happening today

Equal volumes of gas contain equal numbers of particles at the same temp and pressure

examines phenomena that exist or occur in the present

The earliest ACCURATE pressure instrument was built by

parcels with an unbalanced electrical charge

evaluates how exactly a measurement is made

ions with more protons than electrons and have a positive charge

a workable explanation or description 

the process that scientists use to solve problems

when solids seem to evaporate

any particle of matter smaller than an atom

The net force acting perpendicular to the surface and the area which it acts.

the proton is the smallest particle of matter that makes up all other matter

The study of how fluids flow and how forces and energy are transmitted through fluids

any change of the arrangement of the matter in a material or object

His research showed the relationship between temp and the volume of an isolated quantity of gas

anything that occupies a volume of space and has mass
