Temperature (T) and pressure (P) are classified as intensive properties, while volume (V), heat (q), work (w), internal energy (U), and enthalpy (H) are considered extensive properties. The distinction is based on how these variables change with the size of the system. Intensive properties remain constant regardless of the amount of substance, while extensive properties vary with the quantity of material present. The consensus in the discussion confirms this classification. Understanding these properties is crucial for thermodynamics and physical chemistry.

Homework Statement


classify the following variables and functions as intensive or extensive.

T,P, V, q (heat), w (work), U (internal energy), and H (enthalpy)


The Attempt at a Solution



I wanted to check up on my answers for this but I believe on T and P are intensive properties. And the rest are extensive: V, q, w, U, and H

Sounds good to me.
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
