Black hole- an object so dense that even light cannot escape its gravity
Red Giant - a large star that is relatively cool
White Dwarf - an old, very dense hot star that is cooling
Nebula - A mass if gas and dust
It depends. In a typical US residence with 120/240v single-phase power, the ground wire will be green, the neutral will be white, and the hot conductor will be either black or red depending on which phase it is connected to. Odd numbered breakers (1,3,5, etc.) are black, and even numbered breakers are red. You will measure 120v from black to white, also 120v from red to white, but 240v from black to red. In a commercial building with 3-phase 120/208 power, ground and neutral are the same color, but there are 3 hot colors - black (a-phase) red (b-phase) and blue (c-phase). As you run down a line of breakers from top to bottom they will be wired: black red blue black red blue etc. You will measure 120v from any of the 3 hot colors to white (neutral) but 208v from black to red, red to blue and blue to black.
Hot tea is normally drinkable at between 60°C and 65°C (140 to 150°F). It cools from the temperature at which it is brewed, especially if milk is added. The water for tea is normally brought to a full boil before the brewing process. The temperature used for brewing tea depends on the type of tea, but may range from 75°C for white teas, to 80°C for green tea, to 90°C for Oolong teas and full boiling temperature for black teas.
