Answer #1

a)

Given:

Ti = 282.0 oC

= (282.0+273) K

= 555 K

Vi = 569 mL

Vf = 476 mL

use:

Vi/Ti = Vf/Tf

569.0 mL / 555.0 K = 476.0 mL / Tf

Tf = 464 K

= (464 - 273) oC

= 191 oC

Answer: 191 oC

b)

Given:

Vi = 10.1 L

Ti = 26.0 oC

= (26.0+273) K

= 299 K

Tf = 66.0 oC

= (66.0+273) K

= 339 K

use:

Vi/Ti = Vf/Tf

10.1 L / 299.0 K = Vf / 339.0 K

Vf = 11.5 L

Answer: 11.5 L

c)

Given:

Vi = 8.96 L

Ti = 40.0 oC

= (40.0+273) K

= 313 K

Tf = -9.0 oC

= (-9.0+273) K

= 264 K

use:

Vi/Ti = Vf/Tf

8.96 L / 313.0 K = Vf / 264.0 K

Vf = 7.56 L

Answer: 7.56 L
