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.
Eat a banana or an apple. Bananas contain natural antacids that can act as a buffer against acid reflux. If you want to try out the simplest home remedies for heartburn first, try letting a few bananas ripen up nicely and eating one every day. Another option is to try an apple a day.
