center – a ball does!• B. i. > plastic cools faster – does not hold heat
like styrofoam• ROCK IS BETTER INSULATOR

• 3.C. i. > Large cube 1 cm28 small cubes – approx 8 cm2-more area
C. ii. > Small cubes cool faster
C. iii. > small mass losses heat faster
Exercise 3 -52
• Phaneritic- course-cooled slowly-should have crystal-ions migrated slowly and formed crystals-nucleation possible
• Aphaneritic-fine ( cools fast! Less time for Na+ to migrate-no crystal formation
Exercise 3- page 52
