A balloon at 32 °C is filled with 21 L of air. What would its volume be at a temperature of 52 °C, assuming pressure remains constant?
Assuming the gas is ideal, we use Charles' Law to relate the relationship between Temperature & Volume of gas:
V1/T1 = V2/T2
T1 = initial temperature of gas (in K)
T2 = final temperature of gas (in K)
V1 = initial volume of gas
V2 = final volume of gas
*note that to convert °C to K, we just add 273.
(21)/(32 + 273) = V2/(52 + 273)
V2 = (21)*(325)/(305)
V2 = ?
now solve for V2.
hope this helps~ :)
I wanted the full answer fam fym solve for V2 Bit!!! you solve for it!!
