Two liquids are poured into two cups. cup a contains a colorless, odorless liquid. cup b contains a colorless liquid with a strong odor. an ice cube floats in cup a but sinks in cup b. when heated, the liquid in cup b boils at a much lower temperature than the liquid in cup a. what kind of properties are used to compare the two liquids? a) visible b) chemical c) physical d) phase change

the correct answer is C. physical

c physical

Explanation:

Physical properties are used to compare the two liquids. Both water and rubbing alcohol have the same clear color while their boiling points, odor, and densities are all different.

there was no answer choices but i think its representative

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
