1. Describe the construction of a tin oxide-based CO gas-sensor paying particular attention to essential design features.

2. Give a quantitative estimate of the relative annual energy requirements for maintaining living comfort (23
C) in two locations where the outside temperatures are averaging, respectively, 13
C and 33
C. The effects of relative humidity on comfort may be ignored.
