Answer:
A. True
Explanation:
The octane number is determined by comparing the characteristics of gasoline to isooctane (2,2,4-trimethylpentane) and heptane. The correct option is option A.
Basically, the higher the octane number, the greater the resistance of the gasoline to knocking.
<u>Answer:</u> The correct answer is Option B.
<u>Explanation:</u>
To calculate the final pressure of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant volume.
Mathematically,
(at constant volume)
where,
are the initial pressure and temperature of the gas.
are the final pressure and temperature of the gas.
We are given:
Conversion factor: 

Putting values in above equation, we get:

Hence, the correct answer is Option B.
