Chapter 2 THURSDAY!!!!!

element- one type of substance ex) periodic table

Compound- a mixture of 2 chemically ex) table salt

Mixture- purely physical substances ex) tea, coffee, ocean water

specific heat, heat_grams x temp= j/cal _ gram x temp ... so equation will be Mass x temp change x cal/j_ g and temp

1 Cal= 1 kcal= 1000 cal

1 Cal= 4.184 kJ= 4184 k

temp and state changes- melting and freezing points

Heat = mass x ( Heat fusion- 80 cal_ 1 g water or 334J _ 1 g water )

Heat = mass x ( Heat vaporization - cal = g x 540_ g or J = g x 2260J_ g )
