Problem: The accompanying photo shows a pipevine swallowtail caterpillar climbing up a twig. If the caterpillar is the system, can you predict the sign of q as the caterpillar climbs?

FREE Expert Solution

We’re being asked if we can predict the sign of q as the caterpillar climbs if the caterpillar is the system.

The internal energy(ΔE or ΔU) of a system can be calculated from the heat and work of the system. The relationship between internal energy, heat, and work is shown in the following equation:


U = q + w

where

ΔU is the total change in internal energy of a system,

q is the heat exchanged between a system and its surroundings, and

w is the work done by or on the system.
