Answer:
A. 2
B. 1.14
Step-by-step explanation:
A. Data obtained from the question include:
Initial temperature (T1) = 48K
Final temperature (T2) = 96K
Final pressure (P2)/initial pressure (P1) =?
Since the volume is constant, we shall determine the ratio of final pressure to initial pressure (P2/P1) by applying the following equation:
P1/T1 = P2/T2
P1/48 = P2 /96
Cross multiply
48 x P2 = P1 x 96
Divide both side by 48
P2 = P1 x 96/48
Divide both side P1
P2/P1 = 96/48
P2/P1 = 2
Therefore, the ratio of final pressure to the initial pressure is 2
B. Data obtained from the question include:
Initial temperature (T1) = 26°C = 26°C + 273 = 299K
Final temperature (T2) = 68.7°C = 68.7°C + 273 = 341.7K
Final pressure (P2)/initial pressure (P1) =?
Since the volume is constant, we shall determine the ratio of final pressure to initial pressure (P2/P1) by applying the following equation:
P1/T1 = P2/T2
P1/299 = P2 /341.7
Cross multiply
299 x P2 = P1 x 341.7
Divide both side by 299
P2 = P1 x 341.7/299
Divide both side P1
P2/P1 = 341.7/299
P2/P1 = 1.14
Therefore, the ratio of final pressure to the initial pressure is 1.14
