sludge is a mix of different items and substances that you have to identify.

# data[].attributes.body
micro melting point is the first sign of melting in a frozen substance.
freezing point will be the same temperature as micro melting point but you identify it by the first sign of freezing.

# data[].attributes.body
Micro- helps determine melting points of non-metals between 23-100 Celsius
Evaporating dish- up to 300 degree Celcius. cannot know exact tempature

# data[].attributes.body
the amount of a salute that can fit in a solvent.

# data[].attributes.body
salute: the substance getting dissolved
solvent: the substance doing the dissolving
concentration:  strong
dilute: not very strong

# data[].attributes.body
have: liquid, Bunsen burner, thermometer, and test tube.
Put liquid in test tube then stick the thermometer in it too. turn on burner and watch the liquid once it starts to bubble look at your thermometer and recored the tempature it started to boil at.

density = mass/volume
find the mass by finding the difference. find the volume by going to the nearest tenth. don't forget numbers and units.

# data[].attributes.body
An intrinsic property is a property that an object or a thing has of itself, independently of other things, including its context.

# data[].attributes.body
density, boiling point, flammability, sugar test

# data[].attributes.body
solubility of water and alcohol
micro melting point if it dosnt melt or do anything use the Evap. dish
Reaction with acid

# data[].attributes.body
if square or rectangular use L*W*H for volume. if odd shaped use water displacement. then find the density

# data[].attributes.body
put a certain amount of ml water then put the object in and see how much it goes up and thats the volume in it.

# data[].attributes.body
1: Oder 2: flammability 3: density
4: boiling point 5: solubility of sugar

# data[].attributes.body
if it reacts to the acid there will be bubbles and make sure to look closely so you don't miss them they can be hard to see

# data[].attributes.body
to find a plastic you only need to test 2-4 times to find the answer and you need to do the tests in order so you don't get it wrong or confused.

# data[].attributes.body
units will be 10% of your grade
Mr. Gipson do not forget to label everything correctly and efficiently

# data[].attributes.body
fractional distillation is when you separate mixtures to find all of the stuff in it

# data[].attributes.body
Check magnitism and use the acid test aswell
