1 C. Temperature – measure of the amount of molecular movement Important Temperatures to Memorize Centigrade (C°) Fahrenheit (F°) Results 0°32°Water freezes 37°98.6°Average Body Temp 21°70°Room Temp 100°212°Water boils

2 Measuring temperature: 1. Mercury or alcohol thermometers 2. Digital Thermometers

3 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

4 Measuring mass: 1. Triple balance beam 2. Digital scales

5 E. Time (seconds)– duration; Measuring devices: 1. stopwatch 2. digital timers

6 F. Mole – the amount of a substance (mol) Not this!!

7 F. Mole – the amount of a substance (mol) mole = 6.022 x 10 23 particles of a substance Ex: a mole of popcorn = 6.022 x 10 23 of kernels of popcorn Enough popcorn to cover the entire US at a height of 310 ft!

8 The mole is showing the value of a mole Happy mole day….October 23 rd !
