determining what metal it was by using the formula q=c X m X change of temperature. We did two trials to compare the two and see what we come up with. EXPERIMENTAL First we chose an unknown metal‚ in which our unknown was unknown metal 2‚ the metal was gray and irregular shaped. We setup the calorimeter and got a mass of it just being empty then we got a mass with 30mls of water in it. We found the mass of the water by subtracting the mass of the empty calorimeter which was 49.987g and the mass of the

If the spray continues the latent heat keeps the ice temperature at 0 degrees Celsius acting as a protective layer to subfreezing temperatures in the air. 3. Would a strong radiation inversion be more likely to form on a winter night or a summer night? Explain your answer. A strong radiation inversion would form on a winter

Mold needs four important elements to grow: moist‚ warmth‚ air‚ and darkness. I combined these four elements to conduct this experiment. Five different food sources were selected and incubated for seven days. At the conclusion of the experiment‚ I was able to view different types of mold‚ with the naked eye. Then I was able to compare and contrast any differences or similarities that I observe with the mold specimens. The five food samples selected for task #1 was a slice of white bread

The first frames of all the layers are keyframes and are indicated by a gray background and black dot. The remaining frames are all blank. Continuing with the tutorial let us begin to animate the wheel in the "wheel animation" movie clip by creating new keyframes within the movie clip’s timeline. Getting into the "Wheel Animation"
