requires energy to be removed (3)

IN OUR LAB:

We heated water; once it reached _____degrees C its temperature did not go up, even when we were heating it. This is because the heat was being used to change ____ to ____. When we plotted this information on a graph, we could see a ___________ that indicated the phase change. When water boils, the bubbles are water _____. Many people think the bubbles are _________ and __________; if that were true, it would be dangerous to boil water!

When we cooled water we used a salt and ice. Salt ________ the melting pt of water; the salt ice mixture reached about ________ degrees C. When we put the test tube of water in this bath, the temp went down and the graph formed a _________ at ________ degrees C; this showed us the ___________ pt of water.

Paradiclorobenzene is a ________ at room conditions, but a _________ at 95 degrees C.

Its uses include ________________ and ______________________. The temperature went down the graph made a __________at _______degrees C; this showed us the _____________pt for paradiclorobenzene. Freezing point is always _________ the

Melting pt.

What does kinetic mean? What is the main idea in kinetic theory?

What are some properties of gases that can be explained by kinetic theory? Use kinetic theory to explain these properties.
