Interesting facts/Misc
100
What are the three states of matter?
What is Liquid, solid and gas.
100
What happens to the viscosity of a liquid if you (1)heat/(2)cool it?
What is becomes (1)less/(2)more viscous.
100
Why is salt soluble in water?
What is salt's particles are attracted to water and since water's particles move faster than salt, they pull the salt particles apart and combine with them.
100
What is a ratio?
What is a comparison of units that are the same.
100
What is it called when a solid turns into a liquid.
What is melting or fusion.
200
What is happening in (1) gas, (2) solid and (3) liquid on the particle level?
What is (1) the particles are moving very fast and are very far apart, (2) the particles are moving very slow and the spaces inbetween them are very small and (3) the particles are moderatly fast and have moderatly big gaps inbetween them.
200
What happens to the viscosity of a gas when you (1)heat/(2)cool it?
What is it becomes (1)more/(2)less viscous.
200
Why does powdered sugar dissolve in water faster than granulated sugar?
What is the actual grains of powdered sugar are smaller allowing more water particles to attract the sugar particles.
200
What is a rate?
What is a comparison of different types of units.
200
What is it called when a solid turns into a gas or when a gas turns into a solid.
What is Sublimation.
300
How does a solvent dissolve a solute on the particle level?
What is the solute's particles are attracted to the solvent and since they are moving (fast) they eat away at the solute until it all has combined.
300
What is flow rate?
What is find the amount of time it takes a liquid to travel a predetermined distance.
300
Define concentration.
What is the amount of solute in a given amount of solvent.
300
Would you use a ratio or rate when demonstrating a the viscosity of a liquid.
What is rate.
300
Another word of a heterogeneous mixture?
What is a mechanical mixture.
400
What are the particles that make up water.
What is 2 parts hydrogen, 1 part oxygen.
400
What happens to the particles of a liquid when it is heated/cooled?
What is particles move faster/slower and the spaces in-between become bigger/smaller.
400
Define solubility.
What is the amount of solute that can be dissolved by a solvent.
400
Define equivalent ratio.
What is a ratio that has different numbers but tells or shows the same relationship/fraction.
400
Another word for homogeneous mixture?
What is a solution.
500
Name the 5 parts of the PMM.
What is all substances are made up of tiny particles. All particles in a pure substance are all the same. Different pure substances are made of different particles. The particles have spaces between them. Particles are always in motion, the speed of the particles increase/ decrease when the temperature increases or decreases. Particles are attracted to each other. The strength of the attraction depends on the type of particle.
500
How do you calculate flow rate?
What is find the amount of time it takes a liquid to travel from one place to another and then divide the time by itself so you get 1. Then dived the distance by the same number.
500
Why do some things dissolve and others don't?
What is particles are attracted to their original positions and particles that they cannot be separated.
500
What is a proportion?
What is number sentence that includes and equals sign and has two or more equivalent ratios.
500
What is the difference between a homogeneous mixture and a heterogeneous mixture?
What is a heterogeneous mixture can be easily separated while a homogeneous mixture cannot be easily separated.
