1. A man fills a balloon with .5 liters of air. He then puts the balloon into the oven and heats it to 204•C. The temperature outside the oven was 20•C.

- 1A - what is the new volume of the balloon?

- 1B - what gas law is used to solve this?

2. A hot air balloon descends from a pressure of 380 mm Hg to 760 mm Hg and at the high altitude has a volume of 1,000 cubic meters. The initial temperature is 50•C and drops to 25•C.

1. f(x)=-3^2+12x-2

2. y= -x^2-2x+8

#1. Avogadro's hypothesis states that equal volumes of gas under the same conditions have varying number of molecules.

#2. mole is the name given to the mass of any gas necessary to occupy 25.0 liters of gs at 1 atmosphere.

#3. a product is the result of two substances reacting together

#4. the mass of a mole of diatomic gas is equal in grams is equal in grams to three times the atomic mass.

#5. in balanced equation the numbers preceding the molecules re ratios of the units either in mole or molecules units (example: 2H2 + O2 ====> 2H2O)

#6. Einsteins law of conservation of mass-energy (E=me2) says that atoms are destroyed in chemical reactions

#7. scripture says in the beginning god created all things (genesis), god completed his work, and now god sustains all things. conservation of mass-energy supports this.

#8. recycling our natural resource is not important to our survival on this planet.

#1. a temperature scale used with gas laws starts with absolute zero and is called the kelvin or absolute temperature scale.

#2. the variables that affect the gaseous state include volume, temperature, or number of gas molecules.

#3. under real conditions, one variable of gas (pressure, volume, temperature, or number of molecules) usually affects just one other variable.

#4. the combined gas laws is the result of the mathematically combining Boyle's law and Charles' law

#5. STP stands for standard time and pressure

#1. y=x^2+4x+3

y= 2x+6

#2.y=x^2-6x+8

2y+x=4

#3.y=-x^2+2x+4

x+y=4

#4. y=x^2+2x+7

y=x+7

for each i need to know

1) find the value(s) of x
