job. Unfortunately‚ most of the powers that are of interest to me‚ especially the ability to bend space and time and invisibility‚ have been taken. What’s a fledging superhero to do? I flirted with shape shifting or the ability to manipulate the weather. I thought about being able to communicate with animals‚ but other than being very Dr. Doolittle-ish‚ how would that come in handy when trying to save the world? It wouldn’t. No‚ it would have to something formidable. So‚ after much thought‚ I’ve

until its volume is 4.8 L‚ what will the new pressure inside the piston be? P1V1 = P2V2 (1.5 atm)(5.6 L) = (x)(4.8 L) x = 1.8 atm 2) I have added 15 L of air to a balloon at sea level (1.0 atm). If I take the balloon with me to Denver‚ where the air pressure is 0.85 atm‚ what will the new volume of the balloon be? P1V1 = P2V2 (1.0 atm)(15 L) = (0.85 atm)(x) x = 18 L 3) I’ve got a car with an internal volume of 12‚000 L. If I drive my car into the river and it implodes

Analysis During the experiment‚ a dialysis bag was used to mimic a cell membrane. Two ways why this model realistically represents a cell is because the dialysis bag is semi-permeable‚ like a cell. The bag was able to allow water in‚ as the size of the water molecule was small enough to be able to fit through the pores of the bag. Sucrose was not able to pass through as the molecules were too big to enter. This is similar to a cell because the size of a molecule can determine whether or not the

First of all‚ the video discuss that “the universe is constantly expanding… like balloon.” Hawking explains this by a simple demonstration of the Doppler Affect.

These companies heavily depend on foreign gasoline oils or imported oils for adequate supply and are spending not only billions but trillions of dollars for the import of gasoline oils. The Philippines rank___among the oil importing countries‚ garnering 0.77% of the world’s import

GAS LAWS Properties of Gases Gases expand into any available volume • gas molecules escape from open containers. Gases are completely miscible • once mixed they will not spontaneously separate. Gases are described in terms of T‚ P‚ V and n Volume‚ Amount and Temperature • A gas expands uniformly to fill the container in which it is placed – The volume of the container is the volume of the gas – Volume may be in liters‚ mL‚ or cm3 • The temperature of a gas must be indicated
