Additive interaction means the effect of two chemicals is equal to the sum of the effect of the two chemicals taken separately. This is usually due to the two chemicals acting on the body via same or similar mechanism.
Rating Newest Oldest. Best Answer: The maximum adiabatic flame temperature a propane torch can achieve with air is 2268 kelvins (1995 Â°C / 3623 Â°F). The maximum adiabatic flame temperature a butane torch can achieve with air is 2243 kelvin (1970 Â°C / 3578 Â°F). There is more to it than simply the temperature of the flame.
1 gallon of propane is about 90,000 BTU/hour.   : A 20 lb tank holds a little more than 4 gallons.   : My patio propane fireplace is 60,000 BTU. At full blast, a 20 lb t â¦ ank will last about 6-7 hours, which is really close to the calculation.he MH80CV, part of the Mr. Heater Contractor Series, is a 30,000-80,000 BTU Propane Convection heater. The MH80CV provides reliable heat for areas up to 1900 sq. feet. It wil â¦ l operate for up to 14 hours on a 20-lb propane tank.
