The flammable range of ammonia in dry air is 15.15–27.35% and in 100% relative humidity air is 15.95–26.55%. ... ammonia is much more ... and the temperature of ...
Otherwise temperature is equilibrium of vapor over liquid. log 10 of anydrous ammonia vapor pressure. Uses formula shown below. Vapor-pressure formula for ammonia: [4]
The contribution of the muscle to the specific heat of the body is approximately 47%, and the contribution of the fat and skin is approximately 24%. The specific heat of tissues range from ~0.7 kJ · kg−1 · °C−1 for tooth (enamel) to 4.2 kJ · kg−1 · °C−1 for eye (sclera). [13]
Household ammonia ranges in concentration by weight from 5% to 10% ammonia. [9] US manufacturers of cleaning products are required to provide the product's material safety data sheet that lists the concentration used. [10] Solutions of ammonia (5–10% by weight) are used as household cleaners, particularly for glass.
When also held to normal pressure, ammonia's melting and boiling points are −78 °C (195 K) and −33 °C (240 K) respectively. Because chemical reactions generally proceed more slowly at lower temperatures, ammonia-based life existing in this set of conditions might metabolize more slowly and evolve more slowly than life on Earth.

Yard Work. Unless you're physically unable to tend your own yard, get out there and get to work.You may even find that you enjoy the exercise and being outdoors.
The ideal reaction has an optimal temperature range between 630 and 720 K (357 and 447 °C), but can operate as low as 500 K (227 °C) with longer residence times. The minimum effective temperature depends on the various fuels, gas constituents, and catalyst geometry. Other possible reductants include cyanuric acid and ammonium sulfate. [3]
A new study found that Americans 40 and older could live over five years longer if they exercised as much as the top 25% of the population. Here's what to know.
