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.
Green tea steeping time and temperature varies with different tea. The hottest steeping temperatures are 81 to 87 Â°C (178 to 189 Â°F) water and the longest steeping times two to three minutes. The coolest brewing temperatures are 61 to 69 Â°C (142 to 156 Â°F) and the shortest times about 30 seconds.reen tea steeping time and temperature varies with different tea.
