<h3>What is the theory of spontaneous generation?</h3>

The theory of spontaneous generation is the theory that living-things can arise spontaneously from non-living things.

Early scientists believed this theory. The experiments by Francesco Redi sought to disprove this theory.

However, it was only the experiment by Louis Pasteur that finally helped scientists at the time to reject the theory of spontaneous generation.

Air at 1 atm was closed into a rigid container. It was then heated to a temperature of 911
otez555 [7]

Answer:

Final temperature, T2 = 2460 Kelvin.

Explanation:

Given the following data;

Initial pressure = 1atm

Final pressure = 2.7atm

Initial temperature = 911K

To find the final temperature, we would use Gay Lussac's law;

Gay Lussac law states that when the volume of an ideal gas is kept constant, the pressure of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Gay Lussac's law is given by;

PT = K

\frac{P1}{T1} = \frac{P_{2}}{T_{2}}

Making T2 as the subject formula, we have;

T_{2}= \frac{P_{2}}{P_{1}} * T_{1}

Substituting into the equation, we have;

T_{2}= \frac{2.7}{1} * 911

T_{2}= 2.7 * 911

Final temperature, T2 = 2459.7 ≈ 2460 Kelvin.
