A nonchemical combination of two or more substances in variable proportions is a mixture.
A chemical combination of two or more substances in variable proportions is called a mixture.
The dependent variable of pH is its acidity. The independent variable is whatever substance is being tested for pH levels.
The substance you are referring to (a combination of corn starch and water) is what is called a non-newtonian fluid. This means that it has variable viscosity which is why it acts as both a solid and a liquid.
No. A pure substances has a definite and constant composition.
The independent variable is the heat of the light bulb, the dependent variable is the heat absorbed by the wax substance (or other convective liquid) which makes the substances in the lamp move due to density convection.
A SUBSTANCE is a material that has constant composition, regardless of its source, also said to be pure. This is opposed to an impure sample one with variable composition which would be called a MIXTURE. subutance
Causes of law of variable proportions
what is relationship between change in input and output. In the return's to scale (long term concept) all the factor are variable but in the variable proportions are some factor variable and some factors are fixed.
conduction, convection, and radiation
the average variable cost curve and average cost curve are u- shaped because of the law of variable proportions.
inconel is a term referring to a group of alloys. Alloys have variable compositions as they can considered to be solid solutions of metals. inconels main constituents are Ni and Cr with many other elemnts in smaller proportions.
A constant variable is a variable that gets changed by a physical substance
The chemical formula is very variable.
The dependent variable of pH is its acidity. The independent variable is whatever substance is being tested for pH levels.
Minerals are basically chemicals in a solid form.A2. Part of the definition of a mineral is that it has a known chemical composition. If its composition were variable, it would not qualify under the definition.
Define variable; Hum0r = 1}Produce is produce: a substance combining with oxygen is most often a mutually exclusive event. Various chemical reactions involving oxygen, however; may have very "explosive" effects on produce. Such a chemical reaction is portrayed here: http://www.youtube.com/watch?v=1Axz42RIUpA}k tnx bye// -- Ages
A constant variable is a variable that gets changed by a physical substance
could i have 5 names of mixtures the 5 names of mixtures are variable mixture,constant mixture,homogeneous liquid mixture,homogeneous solid mixture and chemical mixture
