Answer: Destruction of the ozone
Explanation: Some of the he most common refrigerants used for air conditioning is chloroflurocarbons and hydroflurocarbon that can deplete the ozone layer that is a protective covering.
This covering filters the harmful rays of the sun that is harmful for the human beings and animals on the earth. The coolants contains chlorine which impacts the ozone and cause depletion.
Answer:
874.89 mmHg
Explanation:
Using the combined gas law equation as follows:
P1V1/T1 = P2V2/T2
Where;
P1 = initial pressure (mmHg)
P2 = final pressure (mmHg)
V1 = initial volume (L)
V2 = final volume (L)
T1 = initial temperature (K)
T2 = final temperature (K)
Based on the information provided in this question;
P1 = 950 mm Hg
P2 = ?
V1 = 25 L
V2 = 30 L
T1 = 155°C = 155 + 273 = 428K
T2 = 200°C = 200 + 273 = 473K
Using P1V1/T1 = P2V2/T2
950 × 25/428 = P2 × 30/473
23750/428 = 30P2/473
55.49 = 0.063P2
P2 = 55.49 ÷ 0.063
P2 = 874.89 mmHg
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.
C, they could work together to make things from the top down.
D Because yes steps by step explanation
