Calculate the mass of propylene glycol that must be added to 0.340 kg of water to reduce the vapor pressure by 2.88 ATM at 40 degrees Celsius at 40 degrees Celsius equals 55.3torr?
To calculate the mass of propylene glycol needed, we can use Raoult's law. Given that the vapor pressure of pure water at 40 degrees Celsius is 55.3 torr and the desired vapor pressure when mixed is 2.88 atm, we can calculate the mole fraction of propylene glycol needed. From this, we can find the mass of propylene glycol required to achieve this mole fraction when combined with 0.34 kg of water.
Where does the vapor in electronic cigarettes come from?
The vapor comes from the flavored liquid inside the e-cig. The liquid (usually made of a mix of propylene glycol and vegetable glycerin, with or without nicotine added) is heated just enough to vaporize it (convert it from liquid to gas).
Is the white smoke from burned automotive coolant toxic?
Yes, very toxic. Antifreeze products usually contain one of three active ingredients: Ethylene glycol Propylene glycol Methanol All three ingredients are toxic to humans in liquid or vapor form.
Is propylene glycol bad for humans?
Propylene Glycol USP grade is safe for human consumption, including inhalation. It is used as a germ killer in both solid and gas forms. It's in your prescription drugs. It's in your cosmetics and soaps. It's in your food. It's in your water. It's in tobacco products. It's used in fog machines. It's even in biodegradable antifreeze. All the Material Data Safety Sheets I've found on PG only list a mild respiratory irritation when inhaled as a vapor. Long term exposure is a different story. I haven't found anything on that, but the e-cig users who inhale PG vapors all the time don't report having any problems so far. Added: I found the medical resources on that question: http://www.ncbi.nlm.nih.gov/pubmed/18158714 http://jpet.aspetjournals.org/content/91/1/52.abstract
Is vegetable glycerin vapor safe to inhale?

What is antifreeze smoke?
Antifreeze smoke refers to the vapor or fumes produced when antifreeze, typically containing ethylene glycol or propylene glycol, is heated or burned. This smoke can occur in situations such as engine overheating or coolant leaks, where antifreeze comes into contact with hot surfaces. The fumes can be harmful if inhaled, as they may contain toxic components. It's important to address any leaks or overheating issues in vehicles to prevent exposure to antifreeze smoke.
What will happen when smoke is mixed with vapor?
It's less harsh to inhale.
Natural gas dehydration using triethylene glycol?
Yes dehydration of neutral gas is using triethlene glycol (TEG) because TEG is the best water vapor absorbent.
When you inhale air do you get a small or big amount of water vapour?
Well this depends on the humidity. Lets say the humidity is 20%. This means 20% of the air is water vapor. So approximately 20% of the air you inhale will be water vapor.
What substance has been identified in the vapor that comes out an e-cigarette?
The vapor produced by e-cigarettes has been found to contain various substances, including nicotine, propylene glycol, vegetable glycerin, and flavoring agents. Additionally, harmful chemicals such as formaldehyde, acetaldehyde, and acrolein can also be present, which may arise from the heating process. Studies have shown that some of these compounds can have adverse health effects, raising concerns about the safety of e-cigarette use.
Is distilled water vapor safe to breathe?
Distilled water vapor is safe to breathe. It wouldn't be advised to inhale it, however, just like regular steam.
Is triethylene glycol toxic to breath?
Breathing in high concentrations of triethylene glycol vapor can irritate the respiratory tract and cause symptoms like coughing and shortness of breath. Prolonged or repeated exposure to high levels of triethylene glycol vapor may cause more serious health effects. It is important to always use this chemical in a well-ventilated area and follow all safety recommendations.
