Answer:
1.75 atm
Explanation:
When the pressure that a gas exerts on a sealed container changes from 1.75 atm to 2.64 atm, the temperature changes from 315 K to 475 K.
(2.64 atm) x (315 K / 475 K) = 1.75 atm
The pressure and temperature of a gas in a sealed container are directly proportional. An increase in temperature would imply that the pressure also increased.
Answer:1.75 atm
Explanation:
In a closed system, increase in pressure leads to increase in temperature. Using pressure law, P1/T1 = P2/T2
Data =
P1 =?
P2 = 2.64 atm
T1 = 315k
T2 = 475k
From the equation above,
P1 = P2 * T1 / T2
P1 = 2.64*315 / 475
P2 = 1.75 atm
The correct answer should be
D: incredibly
Best Answer: d
the subject is who or what you are talking about- the glowing red coals
the predicate is what they are doing- looked incredibly hot
looked is your verb because that is what they are doing, how did they look? they looked hot, that is the adverb. the word that describes hot is incredibly, that is the pred adj. because adjectives describe.
Answer:
it developed in the 1830s and 1840s by Samual Morse and other inventors, the telegraph changed long distance communication.
Explanation:
Using the time period, the ability to use telegraphs on moving trains came to be shortly after.
