Most of the fuel on-board a rocket is used in the first few minutes of the mission to achieve an escape velocity of at least 25,000 mph (7 miles per second or 40,000 km/h)âthe speed a rocket must theoretically attain to escape Earth's gravity.
Traditionally Japanese green teas and spring teas are brewed at lower temperatures (160Â°F to 170Â°F) and standard Chinese green teas at higher temperatures (170Â°F to 180Â°F). Pre-warm the teapot or cup (optional): Pour a small amount of boiling water into the pot or cup. When the pot or cup is warm, pour out the water.
Herbal teas, on the other hand, do not contain the Camellia sinensis tea plant, so they can steep much longer than a true tea without becoming astringent or bitter. Temperature: Tea generally requires a brewing temperature of anywhere from 160 to 212 degrees, depending on the type of tea.
