CHM 113 ASU EXAM 1 2025/2026
QUESTIONS AND ANSWERS 100% PASS
Definition of Chemistry - ANS study of properties of materials and changes they undergo
The five major branches of chemistry - ANS Organic chemistry
Inorganic chemistry
Analytical chemistry
Physical chemistry
Biochemistry
Classifications of matter - ANS pure substance, mixture, homogeneous mixture,
heterogeneous mixture, element, compound
Law of constant composition (for compounds) - ANS A compound will always consist of two
or more pure substances
The difference between a physical and chemical property - ANS Physical Property: measured
without changing the substance
Chemical Property: how substance react or change to form different substances
The difference between a physical and chemical change - ANS Physical Change: substance
changes physical appearance without altering its identity

, Chemical Change: substance transforms into a chemically different substance
The six types of phase changes - ANS freezing, melting, vaporization, condensation,
sublimation, vapor deposition
The difference between intensive and extensive properties - ANS Intensive Properties:
independent of the amount of the substance that is present (density, boiling point, color)
Extensive Properties: depend upon the amount of substance present (mass, volume, energy)
The 5 fundamental SI units of measurement - ANS kg, m, s, K, mol
How to convert between Kelvin and Centigrade temperatures; marker temperatures on both
scales in reference to water - ANS Celcius: water freezes at 0 degrees and boils at 100
degrees
K= C + 273.15
Volume - ANS volume = (units of length)^3
= m^3
Density - ANS density = (mass/volume)
= g/cm^3 or G/mL
Giga - ANS G (10^9)
Mega - ANS M (10^6)
Kilo - ANS k (10^3)
Deci - ANS d (10^-1)
