A student performed two experiments and noted her
observations below. Based on the information above,
which of the following best describes the results of the
experiments?
Procedure
Mix 10 ml of pale yellow

minutes,
Select one
Experiment 1
Procedure
Mix 10mg of red powder
to 100ml of clear liquid,
Place on hot plate for 5
minutes, recording
temperature every 30
seconds
Result
Liquid changed color to
translucent dark pink
color. No odor is given
off, but temperature
Increased by 15,
o Experiment the right produced a chemical change; experiment on
the left produced a physical change.
Result
Solid white substance
floats on top of a pale
yellow liquid. No
temperature change
measured, but rotten egg
odor is observed
Both experiments created a chemical change
Experiment on the right produced a physical change, experiment on
the left produced a chemical change.
Both experiments created only physical changes
