Substance A is less soluble in water than Substance B.
In this experiment, we can see that small amount of substance A is present at the bottom of the beaker which means that some amount of substance A does not dissolve in water.
While on the other hand, no substance B is present at the bottom of beaker which shows that all the substance B is dissolved in water so we can made a conclusion that Substance A is less soluble in water than Substance B.

Answer:
c
Explanation:
color chance - evidence
gas formation - is evidence
melting - is not (because its only a change in state, eg. ice--> melts into water) melting is an example of physical chance
odor - is evidence
Is B. The number of the atomic mass can increase or decrease because the number of neutrons is different.
Complete Question
A marine biologist is preparing a deep-sea submersible for a dive. The sub stores breathing air under high pressure in a spherical air tank that measures 74.0 wide. The biologist estimates she will need 2600 L of air for the dive. Calculate the pressure to which this volume of air must be compressed in order to fit into the air tank. Write your answer in atmospheres. Round your answer to significant digits.
Answer:
The pressure required is 
Explanation:
Generally the volume of a sphere is mathematically denoted as
Substituting 
Converting to Liters
Assume that the pressure at which the air is given to the diver is 1 atm when the air was occupying a volume of 2600L
