Chapter 15, Problem 9Q

What are the high-temperature and the low-temperature areas for (a) an internal combustion engine, and (b) a steam engine? Are they, strictly speaking, heat reservoirs?

To determine

The high temperature and low temperature areas of (1)internal combustion engine (2)steam engine

Answer to Problem 9Q

Solution:

For an Internal combustion engine, the ignited gas with air is high temperature region and outside air is low temperature region.

For steam engine, pressurized steam from the boiler is high temperature region and condenser is low temperature region.

Explanation of Solution

For an Internal combustion Engine, where the gas and air mix and ignited in the cylinder is considered as high temperature region and the region outside the air is considered as low temperature region.

For the steam engine, the high pressure steam from the boiler is considered as the high temperature region while the condensed water from the condenser is considered as low temperature region.

Both the engines cannot be strictly called as heat reservoir because they don’t have constant high temperature.
