If 60 cm3 of gas is heated from 27oC TO 50oC, what is the new volume of the gas at constant pressure?
-
A.
32.4cm 3 -
B.
55.7cm3 -
C.
64.6cm3 -
D.
111.1cm3
Correct Answer: Option C
Explanation
V1 = 60cm T1 = 273 +27 = 300K
T2 = 273 + 50 = 323KV2 = ?
V1/T1 = V2/T2 .: V2 = V1T 2/T1 = 60 x 323/300 = 19380/300 = 64.6cm3
