Volume(n) = Volume(0) + Volume(0) (2/25)(tf - t0) =
22 + 22(2/25)(tf-t0) = 22 (1 +2/25(tf-t0))
IF the volume of gas increases by a FACTOR of 2/25 Volume(n) = new volume V(0)= original volume= 22 tf=final temp in degrees C t0 = original temp in C
If the volume only increases by 2/25 liter for each degree (NOT a FACTOR)
Volume(n) = 22 + (2/25)(tf-t0)
Volume(n) = 22 + (2/25)(tf-t0) If 2/25 is a liter measurement
Volume(n) = 22 (1 +2/25(tf-t0)) If 2/25 is a FACTOR in the question .... the question is unclear (I suspect the second equation is the correct one)
