Question

When the volume of a gas is changed from 1146 mL to 765 mL, the temperature will change from __ K to 640 K

Answer 1

Step-by-step explanation:

According to Charles rule,

`(V_(1))/(T_(1))=(V_(2))/(T_(2))`

V₁ = initial volume = 1145 mL

V₂ = final volume = 765 mL & T₂ = final temperature = 640 K

`(1145)/(T_(2))=(765)/(640)\\\\\\Cross \multiply\\\\1145*640=T_(2)*765\\\\(1145*640)/(765)=T_(2)\\\\T_(2) = 957.9 \ K`
