Change is Normal!
An example of this would be my backpack tearing open from carrying so many books!
What is physical change?
I told my friend the temperature was 90 outside. They freaked out, because I did not specify which of these three.
What are Fahrenheit, Celsius, and Kelvin?
Between 1 lb of feathers and 1 lb of steel, this would determine which is more dense.
What is volume?
I was certain I had the experiment down to a tee, but my results are all over the place! I guess my experiment was not as this as I thought it was.
What is precise?
The number 893 has 3 sig. figs. because of this rule.
What are non-zero numbers are always significant?
A car running over a firework that was ready to launch caused this change, and prevented this other one.
What are a physical and chemical change?
That 1 in = 2.54 cm, 1kg = 2.2 lb, and 3.2 ft = 1 m are examples of this.
What is a conversion factor?
Between intensive and extensive properties, density falls under this property.
What is an intensive property?
I may be bad at basketball, but I always get at least one this shot before I leave the court.
What is accurate?
It is the amount of significant figures that 430. has.
What are four significant figures?
It got so hot outside, this type of property is what caused this type of change when my ice cream melted!
What is a physical property and a physical change?
I accidentally pressed the wrong button, and now my scale says I have 1000 g of water! Now I don't know how many liters I have... Good thing I can use these two conversion factors to find out!
What are 1 g = 1 mL and 1 cm3 = 1 mL?
I have a tennis ball in one hand that feels much heavier than the bowling ball I have in the other hand. This ball is denser.
What is the bowling ball?
Every time I practice soccer, I almost never score; I have a bad habit of always kicking the ball too far up to the right! At least I can say I am this.
What is precise?
This is the reason 5360 has 3 sig. figs., but 32.000 has 5 sig. figs.
What is a decimal point?
When money used to just be cash, it had this property, but now that everything is digital, it might be this property instead.
What are extensive and intensive properties?
I was confused when it said the cereal cost 32 cents per gram, so I decided to convert it to this many dollars per pound. (2.2 lb = 1 kg; $1 = 100 cents)
What are $145.45/lb?
I have 100 lb of putty. I would need to take away this to make it less dense, or add this to make it more dense.
What are mass and volume?
My graduated cylinder reads at 5.67 mL. However, I do not see any labels indicating the degree of this, so perhaps I will just write down 5.7 mL.
What is certainty?
When 6312 x 41 = 258,792, I know I only need two significant figures. To show this, I need to write it like this, instead of 260000, to avoid confusion.
What is 2.6 x 105?
A chewed apple was then digested, showing these changes, and as far as my stomach is concerned, this property matters most.
What are physical and chemical changes, and extensive properties?
If a copper wire sold for 99 cents/ft3, I could sell it for this many dollars much if I melted it into a 512 cm3 cube. ($1 = 100 cents; 1 ft = 12 in; 1 in = 2.54 cm)
What are $0.02?
I dropped my ring into a graduated cylinder in the lab! It weighed 6 g, and my initial reading of 25 mL is now 28 mL. Well, at least now I know it has this density.
What are 2 g/mL?
Two functioning similar scales that measure two digits past the decimal point, but differ in that only one is labeled for certainty, show that the unlabeled one compromises this, but not this.
What are accuracy and precision?
If multiplication rounds off to the smallest number of significant figures, and addition/subtraction rounds off to the smallest number of decimal places, I know that (150.0+50) x 2.00 = this.
What is 4.0 x 102?
