What was the initial temperature of a gas contained in a 2.0-L bottle at a pressure of 1.00 atm if it was placed under vacuum and its pressure was reduced to 0.82 at mat a temperature of 10.0º C? Assume pressure remains constant

Respuesta :

V1/T1 = V2/T2 

Substitute the value use ratio and proportion. Use calculator. 

V1 = (V2 x T1) / T2

1 is initial, 2 is final
