Answer: P = 1.37 atm
Explanation: For this problem we will use the Gay Lussac Law which is P1/T1 = P2/T2 then derive for P2 which is the outside pressure. Also remember to convert the units of temperature from °C to Kelvin.
T1 = 20°C + 273 = 293 K
T2 = -5°C + 273 = 268 K
P2 = P1 T2 / T1
= 1.50 atm ( 268 K ) / 293 K
= 1.37 atm
Cancel out the units of K so that the remaining unit will be in atm.
I believe when you mix two things up together. It is called mixture. And they make one Compound. One example could be water, sugar, and flavorings making one compound which is soda. Hope it helps.
