A method of writing or displaying numbers in terms of a decimal number between 1 and 10 multiplied by a power of 10.
measurement expression comprise of all digits that are known with certainty, plus the 1st digit that is unknown
the ratio of the mass of an object to the volume occupied by that object
A measure of how hot (or cold) something is; specifically, a measure of the average kinetic energy of the particles in an object.
substances that can not be further decomposed by ordinary chemical means
substances that can be decomposed into two or more simpler substances by ordinary chemical means
physical combination of two or more substances

1) All matter is made of atoms. Atoms are indivisible and indestructible.
2) All atoms of a given element are identical in mass and properties
3) Compounds are formed by a combination of two or more different kinds of atoms.
4) A chemical reaction is a rearrangement of atoms.

A two-stage cascade refrigeration system operates between $T_C = 210 K$ and $T_H = 305 K.$ Intermediate temperatures are $T'_C = 255 K$ and $T'_H = 260 K.$ Coefficients of performance $\omega$ of each stage are 65% of the corresponding values for a Carnot refrigerator. Determine $\omega$ for the real cascade, and compare it with that for a Carnot refrigerator operating between $T_C$ and $T_H.$
