What is Solubility?
What is a solute?
What is a solvent?
Identify the solute & solvent in the following solutions:
How does temperature affect solubility?
How does surface area affect solubility?
How can you increase the surface area of a substance (sugar cube)?
How does stirring affect solubility?
How does the amount of gravity affect weight?
Why do we have less weight on the moon?
What is buoyancy?
Identify the physical properties of matter.
Identify the chemical properties of matter.
Which property of a substance indicates whether the substance is a liquid or a solid at room temperature?
(1) melting point
(2) electrical conductivity
Under which conditions would a sugar cube dissolve most quickly when placed in a liter of water at room temperature?
(1) A whole sugar cube is added and the water is stirred.
(2) A whole sugar cube is added and the water is not stirred.
(3) A crushed sugar cube is added and the water is stirred.
(4) A crushed sugar cube is added and the water is not stirred.
All of the liquid from a test tube is poured into a beaker, as shown in the diagram below.
Compared to the liquid that was in the test tube, the liquid in the beaker has
(1) a different volume, but the same shape
(2) a different volume and a different shape
(3) the same volume, but a different shape
(4) the same volume and the same shape
Diagrams A and B show models of how the molecules of the same substance are arranged in two different phases of matter.
Which phases of matter are represented by diagrams A and B?
The data table below shows that as the pressure of a gas sample was changed, the volume of the gas changed. The pressure was measured in atmospheres (atm) and the volume was measured in milliliters (mL).
According to the data table, as the pressure of the gas increases, the volume of the gas
(3) remains the same
The diagram represents four processes, labeled A, B, C, and D, that occur when water changes phase.
Which process is represented by B?
(1) condensing (3) freezing
(2) evaporating (4) melting
Which two processes increase the motion of the molecules?
(1) A and B (3) C and D
(2) B and C (4) D and A
The graph shows the solubility curves for a solid solute and a gaseous solute.
How many grams of the solid solute will dissolve in 100 grams of water at 25°C?
Describe the relationship between water temperature and the solubility of the gaseous solute from 0°C to 15°C.
State one way to increase the rate at which a solid solute dissolves in 100 grams of water.
