Define exothermic: heat

Volume Notes

Unit of Measurement: cm3

Volume: L x W x H (A x B x C)

Standard unit of length: meter (m)


1 centimeter (1cm) = 0.01m

^ = 100 100 cm = 1 m

unit cube = 1 cm on each side



Volume of Liquids

-use a graduated cylinder to measure volume **Always check the intervals on scale**

-units = milliliters (mL) or cm3

1 mL = 1 cm3
