Explanation:
To mark the upper fixed point, the thermometer is placed in a hypsometer containing water as shown in the figure. The bulb of the thermometer should be outside the water. When the mercury level becomes stationary at a temperature of steam, the level is marked, which represents the upper fixed point of the thermometer.
Answer:
13.9atm
Explanation:
Use Boyle's Law: P1V1 = P2V2
Manipulate the equation: P2 = P1V1/V2
Substitute the values: P2 = (1.31atm)(5.51L)/0.520L
P2 = 13.88096atm
Optionally round to 3 sig figs to get 13.9atm
Actually, that does not happen until the protostar becomes a star when nuclear ignition starts and is maintained. It takes awhile for new star to go through its T-Tauri stage and settle down on the main sequence.
<span>A STAR does not reach hydrostatic equilibrium until it on the main sequence. Otherwise, it would remain a brown dwarf with not enough mass to to maintain nuclear fusion for more than 3,000 to 10,00 years. </span>
