A molecular system at room temperature (25 ∘С)(25 ∘С) is found with energy EAEA 95% of the time and with energy EBEB 5% of the time. It is known that state A consists of an ensemble of 3 microstates while there are only 2 microstates in state B. Determine the difference in energies between the two states (EA−EBEA−EB).

Based on the data of Respirstion of Peas at Room Temperature and
Colder Temperature answer the following questions:
1. Write two hypothesis that this experiment is designed to
test
2. Using the general gas law (V= nRT/p) give the variables
that had to be controlled for your data to be valid. State the
controls used for each variable and any means used to correct for
the influence of a variable.
