What is a solution

A liquid with something dissolved in it

What is pressure

Pressure is the amount of force pressing on something. Air pressure is the force with which air presses. The force comes from the bombardment of the moving air particles.

A compelling or refracting influence ie. peer pressuere.

apex- the force of gas molecules hitting their container

Pressure is the continual physical force that is exerted against an object.
The amount of force acting per unit area is called pressure
How does distillation separate a solvent from a solute

What would dissolve the best in water

vinegar

HCI ~APEX

What causes the pressure inside oxygen tanks to change as they are filled

The number of gas molecules changes.
the number of gas molecules changes

What effect does adding a solute have on the boiling point of a solution

Adding a solute to a solution, or some liquid, causes the boiling point to increase.

Think about water, sometimes people throw salt in their water when they're boiling noodles. This causes the boiling point to increase so the water is actually at a higher temperature (although most of the time the amount of salt added isn't nearly enough to cause any measurable change).

What would happen to a sealed bag of chips left in the sun

the bag inside the bag would expand

D:

Which intermolecular force would affect melting point the most

Hydrogen bonding

Which intermolecular force would cause the highest boiling point

Hydrogen Bonding

How does decreasing the temperature affect the volume of a gas

As indicated by Charles's Law, at constant pressure, the volume decreases when the temperature decreases. This is due to slowed collisions between molecules.

What does volatility refer to

the tendency of liquids to form a vapor

Which of the following could a magnet float over network solid semiconductor superconductor molecular solid

A superconductor.

What forms of the ideal gas law would you use to calculate the number of moles of gas

Probable you think to the law of Avogadro.

What is the overall effect adding a solute to a solution

boiling point is increased and freezing point is decreased

What would mix the best with water non polar molecules polar molecules fatty molecules symmetrical molecules

Polar molecules are mixed better with water.

Which molecular solid would have the highest melting point

A solid that has hydrogen bonding would melt the easiest.

Which of the following is an example of a heterogeneous mixture water saltwater dirt or brass

Dirt is a heterogeneous mixture.

What will result from increasing the temperature of gas

Increasing the temperature of gas the volume increase.

Which of the following is an electrolyte solution

The answer is "Ions in water" on Apex
