What is Avogadros Theory?
Equal volumes of gases at the same temperature and pressure contain equal numbers of molecules. :)
What is Avogadros law?
This law give the variation in volume of a gas with amount of the gas. It states that equal volumes of all gases under similar conditions of temperature and pressure contain equal number of molecules.
How does temperature speed affect the reaction?
For endothermic reactions the increase in temperature increases the K.E of the molecules and numbers of effective collisions per unit volume per unit time among reacting molecules becomes increased so rate of the reaction also becomes increased.
What do you measure climate with?
Measurements to appreciate climate: temperature, volume of precipitations, atmospheric pressure, speed of winds, humidity, numbers of days with sun etc.
What is the role of water molecules in polysaccharide formation?
No. Polysaccharides are sugars and consist of varying numbers of carbon, hydrogen, and oxygen atoms. Water does not contain carbon (H20 = 2 hydrogen atoms and 1 oxygen atom).

What is Avogardros hypothesis?
Avogadro's law: the principle that equal volumes of all gases (given the same temperature and pressure) contain equal numbers of molecules
What mass of oxygen contain the same number of molecules as 42g of nitrogen?
Both nitrogen and oxygen exist at standard temperature and pressure as diatomic molecules. Therefore, the relative masses of equal numbers of molecules of the substance will the same as the ratios of their atomic masses, which are 15.9994 for oxygen and 14.0067 for nitrogen. The mass of oxygen that contains the same number of molecules as 42 g of nitrogen is 42(15.9994/14.0067) or 48 g, to the justified number of significant digits.
Avogadro said that equal volumes of two different gasses have equal numbers of molecules no matter what kinds of gasses they are?
Avogadro's Law states that one mole of any gascontains always the same amount of particles (molecules) in the same volume if taken at the same temperature AND pressure.
Is polypropylene a solid?
Any substance with a sufficiently large average molecular weight to be called "polypropylene" under normal circumstances is a solid at standard temperature and pressure. However, note that some hydrocarbons, such as hexenes, that could be formed by condensing small numbers of polypropylene molecules, are not solids at standard temperature and pressure.

The pressure of gas decreases with increasing temperature?
If the temperature decreases, the volume is also going to decrease, and if the pressure decreases, the volume is going to increase. So they balance each other out, if they are decreased at the same rate.
What things have positive and negative numbers?

Describe the relationship between temperature and pressure?
The relationship between temperature and pressure is not named after a specific person, like Boyle's or Charles' Laws, but states that the relationship between the temperature and pressure of a gas (usually as observed in a rigid container) is direct. Therefore, as temperature increases, pressure does too.This is Gay-Lussac's law.The temperature and pressure of gasses are related. As the pressure increases the temperature also increases, and vice verse. As the pressure decreases the temperature gets colder.The ideal-gas law may be expressed as PV=nRT.Absolute temperature TNumber of moles (a measure of the number of molecules) nVolume VPressure PRydberg's constant R (some value that makes the numbers and the units work)Obviously, from the equation, you could half the temperature and keep the pressure the same, if, for example, you cut the volume in half. Or you could half the temperature and double the number of moles, and the pressure wouldn't change.
Examples of Avogadro's law in everyday life?
Avogadro's Law: Doubling the number of moles of gas doubles its volume, if temperature and pressure aren't changed.A flat tire takes up less space than an inflated tire.Lungs expand as they fill with air. Exhaling decreases the volume of the lungs.A balloon filled with helium weighs much less than an identical balloon filled with air. (Avogadro's Law implies that equal volumes contain equal numbers of molecules, when pressure and temperature are held constant. Since both balloons contain the same number of molecules, and since helium atoms have lower mass than either oxygen molecules or nitrogen molecules in air, the helium balloon is lighter.)Wet air is less dense than moist air (see the FAQ on gases for an explanation).Or simply, all in all, it's just a matter of quantity of gas. (Quantity refers to it's moles). And as the quantity increases, the volume of it's containre, increases to. :)
