A third type of perm is an exothermic perm. It's a self-timing, self-heating perm and is considered one of the easiest perms to get. Exothermic perms work best for thick, resistant hair and can give you strong, long-lasting curls. They work faster than other types of perms. But they...
Is the freezing of n-octane an endothermic or exothermic process? Explain.For the TBA freezing point determination, what common errors might contribute to a false low value for the freezing point of pure TBA?Water freezes at 0 degrees C, but the cream does not. How does adding "rock salt...
Cold processmay also use a heat source but it’s used to liquefy solidified oils for mixing. The real saponification comes from an exothermic heat reaction between the fatty acids of the oils and and a lye (“base”) they’re mixed with. Cold process soaps take about a day to “cook”...
Is deposition an exothermic or endothermic process? ___ is heat exchange brought about by direct contact with a hot surface. a. Conduction b. Convection c. Radiation The air in an inflated balloon (defined as the system) is warmed over a toaster and absorbs 115 J of heat. As it expands...
Hydrocarbons are usually added to acetylene in order to prevent reactor temperatures from rising due to the exothermic reac- tion. Once the reaction mixture has cooled down, the Carbon Black is separated from the hydrogen. The way Acetylene Blacks are created markedly distinguishes them from thermal...
is that a U-lock in your pocket?does a lock like that provide enough securityfor a bike like that trend cycles tend to come around on an elevator with a guy who actually stinks more than I doand he’s not a messenger socially acceptable but creepy dirty laundrydigging deep to pull from...
(i.e., an exothermic reaction), it is a lot less than what is needed for the water molecules to disperse the strong ionic bonds of the ammonium nitrate, so the overall process is an endothermic reaction, or one that absorbs energy from its surroundings. It's for this reason that solid...
Describe the difference between endothermic and exothermic processes. Give examples of each. How does the average kinetic energy of different gases compare when they are at the same temperature? Write the limitations of the first law of thermodynamics. ...
