A rigid container holds 4.00 mol of a monatomic ideal gas that has temperature 300 K. The initial pressure of the gas is 6.00 * 104 Pa. What is the pressure after 6000 J of heat energy is added to the gas?

The final pressure of the monoatomic ideal gas is 8.406 × 10⁶ pascals.

Explanation:

When a container is rigid, the process is supposed to be isochoric, that is, at constant volume. Then, the equation of state for ideal gases can be simplified into the following expression:

Where:

, - Initial and final pressures, measured in pascals.

, - Initial and final temperatures, measured in Kelvins.

In addtion, the specific heat at constant volume for monoatomic ideal gases, measured in joules per mole-Kelvin is given by:

Where:

- Ideal gas constant, measured by pascal-cubic meters per mole-Kelvin.

If , then:

And change in heat energy (), measured by joules, by:

Where:

- Molar quantity, measured in moles.

The final temperature of the monoatomic ideal gas is now cleared:

Given that , , and , the final temperature is:

The final pressure of the system is calculated by the following relationship:

If , and , the final pressure is:

The final pressure of the monoatomic ideal gas is 8.406 × 10⁶ pascals.

answer is c

explanation:

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
