Answer:
Volume = 30cm³
Explanation:
A block is a geometrical figure and its volume, -look at the figure-, follows the equation:
Volume = Width*Length*Height
As the measurements of the block are 5.00cm, 3.00cm and 2.00cm, the volume is:
Volume = 5.00cm*2.00cm*3.00cm
<h3>Volume = 30cm³</h3>
Answer:
Explanation:
Hello,
In this case, it is widely known that for isochoric processes, the change in the enthalpy is computed by:
Whereas the change in the internal energy is computed by:
So we compute the initial and final temperatures for one mole of the ideal gas:
Next, the change in the internal energy, since the volume-constant specific heat could be assumed as ³/₂R:
Then, the volume-pressure product in Joules:
Finally, the change in the enthalpy for the process:
Best regards.
