The drawing shows the top view of a door that is 1.68 m wide. two forces are applied to the door as indicated. what is the magni

Answer:

Explanation:

According to the principle of energy conservation

all kinetic energy will change into thermal energy to increase its temperature

Next, divide both sides by the object's mass

the resulting temperature change is expressed as

Response:

(a)

(b)

Clarification:

Greetings.

(a) In this case, since the starting volume is 18.5 dm³ and the ending volume is 21 dm³ (18.5 +2.5), we can calculate the work at constant pressure as shown below:

This value is negative as it expands against the given pressure.

(b) Furthermore, if the process is conducted reversibly, the pressure might change, hence, we need to calculate the work using:

The moles are calculated based on the provided mass of argon:

Consequently, the work amounts to:
