The boiling temperature of nitrogen is â195.8 Â°C (â320.4 Â°F), about 13 Â°C (â23 Â°F) below that of oxygen, which is therefore left behind. Nitrogen can also be produced on a large scale by burning carbon or hydrocarbons in air and separating the resulting carbon dioxide and water from the residual nitrogen.
Acidic foods like citrus fruits can stimulate acid production and increase heartburn. Avoid oranges, grapefruit, lemons and their juice. Like citrus fruits, tomatoes and products made from tomatoes (tomato sauce and paste, tomato juice) can stimulate the stomach to produce more acid.
In some cases, I cut off the entire sunburned top of the tomato. Bring a large pot of water to a boil. Fill a large bowl with ice and cold water. When the water is boiling, gently lower the 7-10 tomatoes into the pot of water. I use a large slotted spoon/spatula to do this so as to avoid splashing boiling water on myself. Trust me on this.
