A gas sample is heated from -20 degrees Celsius to 57.0 degrees Celsius, and its volume is increased from 2.00 liters to 4.50 liters. If the initial pressure of the gas is 0.110 atm, what is the final pressure of the gas?

i.e.
P1 = 0.110atm
V1 = 2 liters
T1 = (-20 + 273)K
P2 = X
V2 = 4.5 liters
T2 = (57 + 273)K
we know that
P1.V1/T1 = P2.V2/T2 therefore
to get P2 we say
P2 = P1.V1.T2/T1.V2
Thus we get
P2 = 0.11atm X 2LX330K/253KX4.5L
P2 = 72.6/1138.5 atm
P2 = 0.063768atm
I majored in lit in college. i could say for this poem, you like some history on the poet. It starts out kinda unhappy, with the view. ‘Futures i’ve got divorced’ maximum like refers to deserted hopes and desires. The ‘do no longer seem back’ and knife reference is probable approximately getting over painful suggestions. That it now no longer cuts implies desire. Or probable numbness. The stuff on complacency probable potential he feels he enable somebody down via no longer doing some thing he could desire to have achieved. for this reason the accusatory voices. The final paragraph is a little extra complicated. My experience is that the narrator discovered his existence training and acted in this occasion, for this reason the large advantages. This guy sounds like a soldier to me. one that believes that no longer taking action at some mandatory 2nd led to others harm. Now he’s grew to become that suggestions-set around, and located some peace. He gave up previous and futile tries and took a distinctive lifestyle, and he’s beginning as much as discover his existence extra precious. i do no longer normally like poems, yet my dad and mom spents hundreds that they did no longer have so i could desire to discover ways to interpret then. i’m extra approximately novels, although. returned, you will probable earnings from understanding some thing of this author’s existence. This one is noticeably very own, previous the final experience of the sweetness and cruelty of the international I normally see in lesser poems.
