Answer:
Contact with corrosive substances requires flushing with water and removing contaminated clothes and jewelry. With a fire, people should first evacuate the lab. Once safe, they should close doors, pull the fire alarm, and call emergency services. Anyone who is on fire should stop, drop, and roll.
Explanation:
Because that is what you are supposed to do
The layers of the atmosphere are defined by variations in temperature and pressure with altitude. These include the troposphere (0 to 16 km), stratosphere (16 to 50 km), mesosphere (50 to 80km) and thermosphere (80 to 640km).
First, you should convert the temperature unit to absolute temperature.
Second, you shoul graph the points. Then you will find a pretty linear correlations among the points.
You can pick between using the best fit line or you could observe that as you get to higher temperatures the linear behavior is "more perfect".
I found this best fit line:
P = 2.608T + 14
Then, for T = 423K
P = 2.608(423) + 14 = 1117 mmHg
If you prefer to use the last two points, this is the calculus:
[P - P1] / [T - T1] = [P2 - P1] / [T2 - T1]
[P - 960]/[423 -373] = [960 - 880] / [373- 343]
=> P = 1093.3 mmHg.
You can pick any of the results 1177 mmHg or 1093 mmHg, You need more insight to choose one of them: conditions and error of the experiment for example.
