How does the boiling point of a hydrocarbon change as its carbon chain length increases?
Generally speaking, boiling points increase as carbon chain length increases. This is because there are more atoms present in the hydrocarbon molecule and therefore more intermolecular forces (eg Van der Waals') that must be overcome. In addition the now heavier molecule requires greater energy (heat) to make the phase change to a gas. However, branching decreases boiling point; branched hydrocarbons cannot pack together as closely as unbranched ones, and so intermolecular forces are less strong. So, for example, the bp is higher for butane than 2-methylpropane (even though they contain the same number of C and H atoms).
Is burning gasoline in a lawnmower a physical or a chemical change?
Any burning is a chemical change. When gasoline (mostly a hydrocarbon called octane) burns, or combusts, it reacts with oxygen in the air to produce water vapor, carbon dioxide, and a bunch of heat energy, which your lawn mower engine harnesses to do work (turn the blade.)
Is freezing carbon dioxide a chemical change or physical change?
Frozen carbon dioxide is still carbon dioxide, so it is a physical change.
What is the relationship between polarity and vapor pressure?
They are inversely related. The volatility of a liquid increases with decreasing vapor pressure, as it provides more reversible effect on liquid molecules, so less liquid molecules are able to escape. Conversely, the volatility of liquid increases with decreasing vapor pressure, as it provides less reversible effect on liquid molecules, allowing more to escape.
What is the definition of unsaturated hydrocarbon?
Unsaturated hydrocarbons are hydrocarbons which contain one or more double carbon bonds in the chemical structure. They can become saturated hydrocarbons in the event of chemical reactions which change the structure to have only single carbon bonds - for example this occurs to an extent when unsatured cooking oil becomes saturated during cooking and becomes more solid, saturated in content.
How does the flammability of a hydrocarbon change as its carbon length increases?
When the chain length of carbon increase the flammability decrease.
How does adding a double or trible bond change the shape of the carbon backbone in a hydrocarbon?
you have dr.whelan huh
Is combustion a chemcial change?
Combustion clearly is a chemical change. In the combustion of a hydrocarbon, for example, you begin with the hydrocarbon and after combustion you end up with carbon dioxide (CO2) and water (H2O). This demonstrates that a chemical change has taken place.
How does the chain length of Hydrocarbons change their properties?
The flammability DECREASES as the chain length increases. Methane (C1) is natural gas and by definition very flammable. C20 is basically paraffin wax and it will burn but with much greater difficulty.
What is a chemical change in a candle?
Most candles are made from a hydrocarbon called parafin; it burns, producing carbon dioxide and water vapor.
How does melting point change as the number of carbon- carbon double bonds increase?
As the number of carbon-carbon double bonds increases, the melting point decreases.
What is the origin of the phrase sea change?
The volatility of the oceans...
What is the volatility of vodka?
volatility is the relative rate at which the price of a security moves up and down. Volatility is found by calculating the annualized standard deviation of daily change in price. If the price of a stock moves up and down rapidly over short time periods, it has high volatility. If the price almost never changes, it has low volatility
What is the vega of an option?
Option Vega is the change in the value of an option for a 1-percentage point increase in implied volatility, i.e. the first derivative of the option price with respect to volatility.

Why has East Asia come to occupy a central position in climate change debates?
because of China's rapid increases in carbon emissions
Why does trading stock create volatility?
Simple answer is that volatility is simply price change. Price changes due to supply and demand so when people trade a stock it affects supply and demand.
