1. what are the properties of solids
• fixed shape
• fixed volume
• high degree internal order
• CANNOT be compressed
2. what are properties of liquids
• fixed volume
• adapt to shape of container
• dense and CANNOT be compressed
• FLUID
3. what are properties of gas
• no inherent boundaries
• easily compressed
• easily expanded
• FLUID
4. define conduction
transfer of heat by direct contact
5. define convection
• heat transfer in liquids.
• done by mixing two liquids
• Fluid movements carrying heat energy are called convection currents
heat transfer without direct contact

USED TO KEEP NEWBORN INFANTS WARM
7. evaporation
heat taken from the air...cooling air
8. condensation
• gas turn into liquid
• gives heat back to surroundings...warming air
9. entropy
amount of energy in a system unable to do work
10. enthalpy
total measure of energy in the system
11. F > C
5/9 x (F-32)
12. C > F
(9/5 * 100) + 32
13. P=
H x Dw

14. Pascals principle
pressure of a liquid acts equally in all directions
15. what is Archimedes principle
bouyant force must equal the weight of the fluid displaced by an object
16. when is archemedes principle used clinically
SG in UA copared to water

gases can also be measured  reference to o2 or hydrogen
17. cohesive will create what kind of meniscus
concave
18. adhesive will create what kind of meniscus
concave
19. what is surface tension
cohesive forces that help droplets stay together
20. what is the relationship between water and temperature?
they are inversely proportional
21. Laplaces law
pressure varies directly with surface tension and inversely with its radius
