Mass is defined as the amount of matter that a body contains, and a measure of the inertial property of that body, that is, of its resistance to change of motion (Inertia). Mass is different from weight, which is a measure of the attraction of the earth for a given mass (Gravitation).
Inertial mass and gravitational mass are identical. Weight, although proportional to mass, varies with the position of a given mass relative to the earth; thus, equal masses at the same location in a gravitational field will have equal weights. A mass in interstellar space may have nearly zero weight. A fundamental principle of classical physics is the law of conservation of mass, which states that matter cannot be created or destroyed. This law holds true in chemical reactions but is modified in cases where atoms disintegrate and matter is converted to energy or energy is converted to matter.

What does forces in terms of acceleration mean?
As defined by Isaac Newton, force equals mass times acceleration.
What is Mass is measured against a standard using a .?
Mass is measured against a standard using a balance. A balance compares the mass of an object to known masses, ensuring accurate measurement. The standard for mass is typically based on the kilogram, defined by the International System of Units (SI). This allows for consistent and reliable mass measurements across different contexts.
What is the concept of concentration?
The amount of a substance per defined space. Concentration usually is expressed in terms of mass per unit volume.
By definition one atomic mass unit is defined as 1 12 of the mass of a?
One atomic mass unit is defined as 1/12 the mass of a carbon-12 atom. This standard was established to provide a reference point for comparing the masses of different atoms. It allows for more precise measurements and comparisons in the field of atomic and nuclear physics.
Which measure in the metric system is defined by using an object for a referent?
The kilogram is the measure in the metric system that is defined using an object for a referent. It was previously defined by a physical object known as the International Prototype of the Kilogram, but is now defined in terms of a fundamental constant of nature called Planck's constant.
Which of the following properties is defined in terms of the mass of the solvent?
The property defined in terms of the mass of the solvent is molality.
How can mass be defined in terms of?
The mass of a body is the measure of inertia of that body.
What of these terms is defined as anything that has mass and takes up space?
Matter is a term that is defined as anything that has mass and takes up space.
What is the equation for force in terms of momentum?
Force is defined as mass times acceleration.Momentum is defined as mass times velocity. Acceleration is defined as the rate of change of velocity. Velocity is defined as the rate of change of location in space.
The term formula mass can be applied to ionic compound and molecular compuonds because?
The term formula mass is generally defined as the mass of a unit cell in an ionic compound. Molecular compounds are just defined in terms of molecular mass.
Are volume and mass different?
Mass is defined as the quantity of matter in an object. This is measured in grams as the standard unit. Weight is diffrernt than mass! Volume is defined as the amount of space an object takes up. This is measured in liters.
What is an absolute unit?
An absolute unit is a unit which can be exactly defined in terms of mass, length, or time.

In standard used to compare the outcome of a test?
There are hundreds of standard methods for making measurements, and each method will offer the accepted standard in the field. Standards exist with such organizations as ISO. ASTM, your local Standards Institute, and so on. If you were measuring mass, then the equipment should be traceable to the appropriate national or international standards for mass. Increasingly, there is a trend to attempt to define standards in terms of natural processes. 'How many atoms of Silicon will weigh 1 kilogram.' would be typical of a current search. The measurement of length is now defined in terms of the wavelength of a particular atomic transition. The measurement of time is similarly defined in terms of a specified number of cycles of some natural radiation.
