Amu's are used instead of grams to express things like atomic and molecular weights. 1 amu is equal to 1/12 the mass of a single carbon-12 atom. This is equal to 1.66 x 10^-24 g. Carbon-12 has a mass of exactly 12 amu.
The atomic or molecular mass of an atom is such a small number that it would be impractical to use grams or pounds for computations.
1 u equates to 1.660538782(83)×10−24 g.
Because the weight in grams would be infinitesimally small.
hello
grams/mol
You are measuring mass in any system for which you have standard masses.
Carbon 12
true
12 grams of carbon-12 isotope.
To check mass you have to have scales or a balance scale and some small masses (10 g, 50g , or 100g)
You can find out the weight of an unknown object by using standard masses and a scale.
Science does not use the Fahrenheit scale, it uses the Celsius scale or the Kelvin scale instead.
In a macrscopic scale: alters colour, scent, texture.In a microscopic scale: Break bonds between atoms in a molecule and/or forms new bonds between atoms.
Sure, you can use a balance scale instead.
You are measuring mass in any system for which you have standard masses.

Kelvin is an absolute scale, which makes much more sense once you understand that temperature is related to the speed of atoms (they can't have a negative speed). An absolute scale is one in which the lowest possible temperature is zero. An absolute scale also makes more sense in thermodynamics, where the ratios between two temperatures are often important.
Usually a temperature scale is used to test the relative bond strength between atoms. The temperature required to break the bonds determines the bond strength.
Atoms, molecules, waves and electrons move in a variety of ways, but in general, their movements are perceived on the larger, human scale as heat. In hotter objects, everything is moving faster on the microscopic scale.
