Answer:
1300cm3.
Explanation:
Step 1:
Data obtained from the question.
Initial temperature (T1) = K
Initial volume (V1) = 650 cm3
Final temperature (T2) = double the original = 2K
Final volume (V2) =..?
Step 2:
Determination of the new volume of the gas.
The new volume of the gas can be obtained by using Charles' law as follow:
V1/T1 = V2/T2
650/K = V2/2K
Cross multiply
K x V2 = 650 x 2K
Divide both side by K
V2 = 650 x 2K /K
V2 = 650 x 2
V2 = 1300cm3.
Therefore, the new volume of the gas is 1300cm3
