APCHEM-YPZNLO

Work and heat energy are always viewed from the perspective of the system.

Which of the following BEST describes why this is done?

A

Only the system can have work done on it since the surroundings are too large and complex.

B

Only the system can have heat transferred into or out of it since monitoring heat transfer in the surroundings is difficult.

C

Since work can be done on either a system or surroundings, using the system view is only possible for a simple system.

D

Measuring heat transfer and temperature differences is more accurate due to the ease with which a system can be controlled.
