Question

an ideal gas is compressed from 650 cm³ to 500 cm³ while 150 j of heat energy is removed from it. if the gas's pressure remains constant at 600 kpa during the compression, how much work was done by the gas?

Answer 1

The work done by the gas is -90 J.

Step-by-step explanation:

To calculate the work done by the gas, we can use the equation:

Work = Pressure * Change in Volume

Given that the pressure remains constant at 600 kPa and the initial volume is 650 cm³ while the final volume is 500 cm³, we can substitute these values into the equation:

Work = 600,000 Pa * (500 cm³ - 650 cm³)

Simplifying the equation, we get:

Work = 600,000 Pa * (-150 cm³)

Converting cm³ to m³, we get:

Work = 600,000 Pa * (-0.00015 m³)

Finally, calculating the work, we find:

Work = -90 J
