Atoms and Molecules
What is the smallest unit of an element that retains its properties?
What is an atom?
What type of mixture has a uniform composition throughout?
What is a homogeneous mixture?
What do you call the substance that is dissolved in a solution?
What is the solute?
What does Boyle's Law state about gas pressure and volume?
Boyle's Law states that as the volume of a gas decreases, its pressure increases, provided the temperature remains constant.
What is viscosity?
Viscosity is a measure of a fluid's resistance to flow.
What do you call two or more atoms bonded together?
What is a molecule?
What do you call a mixture that is not uniform and has distinct layers?
What is a heterogeneous mixture?
What do you call the substance that does the dissolving in a solution?
What is the solvent?
What does Charles' Law state about gas temperature and volume?
Charles' Law states that as the temperature of a gas increases, its volume increases, provided the pressure remains constant.
What is density and how is it calculated?
Density is mass per unit volume, calculated as density = mass/volume.
What is the difference between an element and a compound?
An element is a pure substance made of one type of atom, while a compound is made of two or more different atoms chemically bonded together.
What makes up a solution?
What is a solute and a solvent?
Describe what it means for something to have a high concentration
What is a high amount of solute dissolved in a solvent?
Explain what is meant by the term "ideal gas."
An ideal gas is a hypothetical gas that perfectly follows the gas laws and has no interactions between its particles.
Explain how buoyancy works.
Buoyancy is the upward force exerted by a fluid that opposes the weight of an object immersed in it.
Give an example of a compound and list its elements.
What is water (H₂O), which consists of hydrogen and oxygen?
What is the difference between a solution and a mixture?
A solution is a homogeneous mixture where one substance (solute) is dissolved in another (solvent).
How does temperature affect the solubility of solutes in liquids?
Increasing temperature increases the solubility of solids.
How do gas laws apply to balloon inflation?
When a balloon is filled with air (gas), the volume increases as more air is added, affecting pressure based on Boyle's and Charles' laws.
What is Pascal's Law?
Pascal's Law states that pressure applied to a confined fluid is transmitted undiminished in all directions throughout the fluid.
What is the term for a substance that cannot be broken down into simpler substances?
What is an element?
ALSO atom would be fine
What does the word saturated mean?
What is when a solvent can't hold more solute?
What is the term for the maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature?
What is solubility?
What factors can influence gas pressure?
Factors include temperature, volume, and the number of gas particles.
What are 3 of the factors that affect the flow of fluids?
Factors include the fluid's viscosity, temperature, pressure, and density
