Why is a chest type freezer considered to be more efficient than an upright model?
What will be an ideal response?
The chest type freezer has a lid that opens upward. This way the cold air, which is heavier than warm air, stays inside the box where it belongs. On the other hand, an upright freezer has a door that opens from side to side. When the door is opened the cold air "falls" out of the box and is replaced with warm air from the room, which now needs to be cooled.

A liquid has a constant CP=100 J/mol•K. 1 mole of this liquid is confined in a piston-cylinder device, with an initial temperature of T=500 K and pressure P=1 bar. The insulation is removed from the cylinder, allowing it to exchange heat with the surroundings, which can be modeled as a heat reservoir at T=300 K and P=1 bar. The process continues until the liquid in the cylinder reaches equilibrium with the surroundings.
A) Find the change in entropy of the liquid resulting from this process. B) Find the change in entropy of the universe resulting from this process.
