GRAPH- Inquiry 4 Density of air

Directions: 1.Finish calibrating thermometer (steps 9 and 10) 2. Everyone should have completed Qs 4 and 5 on lined paper and STAPLED it to the Inquiry 5: lab sheet. 3. Pick one group members paper to continue questions 6, 7, 8, 9, 10, 11. Discuss these Qs and answer as a group. TRADE OFF WRITERS. These conclusion Qs will be a group grade. Write in PEN. 4. Collaborate and compare your graphs (respiration of fish). On the back of the graph, in PEN: - Interpret your graph- What does it tell us? Include details. - Write about your OWN graph

CONTENT BLAST! - Temperature and Density SOLIDLIQUIDGAS I. Describe how the motion of the particles and the density of a substance change as it is heated. HOMEWORK DISCUSSION- STATES OF MATTER… 2 ways the states of matter differ from each other?

Looking at the visual, can you explain why ice floats on water? Use the word density in your answer.

II. Temperature - measure of the ____________ of the molecules of a substance. _______ temperature = more _______energy movement higherkinetic

III. Matter is ALWAYS in motion… LIQUIDGASSOLID How does the motion of solids, liquids, and gases compare to each other?

A.When matter (solid, liquid, gas) is ________ atoms move ________ and spread out = EXPANSION - Volume ___________, Density ___________ HEATED FASTER INCREASESDECREASES

B.When matter (solid, liquid, gas) is ________ atoms move _______ and closer to each other = CONTRACTION - Volume ___________, Density __________ COOLED SLOWER DECREASESINCREASES

Liquid nitrogen = -320°F = VERY COLD!

C.______ remains constant, regardless of temperature. The ________ changes, which affects the _________. MASS VOLUME DENSITY

IV. _______ = is the transfer of thermal (heat) energy from a hotter to a colder object. A. _______ = the absence of heat (lack of molecular motion) HEAT COLD
