Is there a good use for the good you get from putting Styrofoam in gasoline? Yes, there are good uses for PS concentrated solutions. It is a good adhesive/glue for bonding different materials.
What happens to Sty styrofoam when you put gasoline in it?
Is there a good use for the good you get from putting Styrofoam in gasoline? Yes, there are good uses for PS concentrated solutions. It is a good adhesive/glue for bonding different materials. BUT, safety issues is a major concern. Both gasoline (and all other PS solvents, like acetone, MEK, THF, etc.) What can I use to dissolve Styrofoam? All you need to do is to pour a bit of acetone …

What are some examples of climate change?
All my mechanical engineer friends and I are concerned about climate change, but it’s hard to tell what falls within our realm of control. For example: 1 Biodegradable plastics. Chemistry and material science is not our expertise. 2 Geoengineering. We’re generally not fans of geoengineering. We feel there are much better solutions than try to engineer the planet. 3 Carbon capture. Sure, but this is also very chemistry / material science heavy. 4 Electric vehicles. Yes. 5 What are others we could be doing research and development on?
What is the purpose of napalm powder?
Napalm is typically a dry powder that's mixed with gasoline to create the sticky, goopy substance. It's also got some properties that the styrofoam/gas mix does not have. thats bullshit. all it does is make the gasoline more sticky for fuel bombs.
Is polystyrene soluble in gasoline?
Polystyrene is soluble in gasoline (toluene, really). Just like how adding a lot of sugar makes syrup, adding a lot of polystyrene to gasoline makes a gooey fluid. The resulting goo is still polystyrene, probably with a bit of loose styrene and gasoline in it.
Is styrofoam a good insulation material?

The type of lamp will mostly depend on the purpose of usage and personal needs. Oil lamps are available in all shapes and sizes. These lamps can be hook hanging, free-standing, and wall-mounted.
What type of lamp uses a fiber mantle?
In this type, the liquid fuel will use a fiber mantle enclosed inside a glass held by the metal frame. The traditional lantern and kerosene lamps are available in three different types: – mantle lamp. – central-draught. – and flat-wick. Some of them are designed for portable use.
What happens when the data is right skewed?
That is, there will be some people whose incomes are much, much higher than all the others. When the data are right skewed, the mean will be higher than the median. When they are left skewed (much less common) the mean will be lower than the median.
How to find the mean?
The mean is probably familiar, even if you only know it as the average. Add up the numbers, divide by how many numbers there are, and you’ve got the mean. So, for example, if the IQs of the people in your family are.
When is the mean the best measure of central tendency?
The mean is the best measure of central tendency when the data are roughly symmetric and have no outliers, or when there are outliers, but you want them to be included. Most physical measurements (e.g. height, weight) are examples of the first type, at least if you have a single population (unlike the athlete example).
Is data continuous or categorical?
Data is continuous if it can (at least in theory) take on any number. Data is categorical if it can only take on certain numbers. For example, weight, income, age and IQ are continuous. Choice of whom to vote for (e.g. McCain or Obama) party, hair color, and marital status are categorical.

Is the mean a bad choice?
The mean: When not to use it. The mean is a bad choice if the data are skewed, which means that there is a ‘tail’ to the distribution on one side, but not the other. One common example of this is income. Some people make a whole lot more than the average person, but no one makes that much less.
When is the median good?
