Calculate the work associated with the compression of a gas from 121.0 l to 80.0 l at a constant pressure of 16.7 atm.

6.94 × 10⁴ J

Explanation:

We can calculate the work (W) associated with the compression of a gas at constant pressure using the following expression:

W = -P . ΔV

where,

P is the external pressure

ΔV is the change in the volume

Knowing that 1 atm.L = 101.325 J, the work of compression is:

The positive sign of the work means that the surroundings do work on the system.

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.

answer: cellular respiration takes in food and uses it to create atp, a chemical which the cell uses for energy. usually, this process uses oxygen, and is called aerobic respiration. it has four stages known as glycolysis, link reaction, the krebs cycle, and the electron transport chain.
