CHM 1025 Chapter 1 Exam Questions
with Verified Answers
Chemistry is the study of substances in terms of - --composition
-structure
-properties
-reactions
-what are the branches of chemistry? - -general chemistry
organic chemistry
biochemistry
geochemistry
physical chemistry
-What is the scientific method? - -The scientific method is a set of general
principles that helps to describe how scientists think.
-What does the Scientific Method involve? - --observations, facts obtained
by observing and measuring events in nature.
-an hypothesis, statement that explains the observations.
-experiments, procedures that test the hypothesis.
-a theory, model that describes how observations occur using experimental
results.
-What is the questions for Gas Laws? - -PV=nRT
-how does one interpret a line graph? - -Each point on the graph represents
a volume in liters that was measured at a specific temperature.
The line on the graph indicates that the volume of the balloon increases as
the temperature of the gas increases. This is called a direct relationship.
-measurements - -1 m = 1.094 yd
1 m = 39.37 in.
1 m = 100 cm
2.54 cm = 1 in.
-what is volume? - -Volume, the space occupied by a substance,
is measured using units of m3 in the SI system
is commonly measured in liters (L) and milliliters (mL) by chemists
-measurements for volume - -1 m3 = 1000 L
1 L = 1000 mL
1 mL = 1 cm3
1 L = 1.057 qt
