C. Temperature – measure of the amount of molecular movement
Important Temperatures to MemorizeCentigrade
(C°)Fahrenheit
(F°)Results
0° 32° Water freezes
37° 98.6° Average Body Temp
21° 70° Room Temp
100° 212° Water boils
Measuring temperature:
1. Mercury or alcohol thermometers
2. Digital Thermometers
D. Mass (kg)– measure of the amount of matter in an object
Ex: golf ball vs. ping pong ball
Each have about the same volume but mass is different. Golf ball has about 18x more mass
Measuring mass:1. Triple balance beam
2. Digital scales
E. Time (seconds)– duration;
Measuring devices:1. stopwatch
2. digital timers
F. Mole – the amount of a substance (mol)
Not this!!
F. Mole – the amount of a substance (mol)
mole = 6.022 x 1023 particles of a substance
Ex: a mole of popcorn = 6.022 x 1023 of kernels ofpopcorn
Enough popcorn to cover the entire US at a height of 310 ft!
The mole is showing the value of a mole Happy mole day….October 23rd!
