My wife and I always argue about the temperature in our house. I like it at 281.0 K, while she likes to set the thermostat to 305.0 K. As we take turns constantly changing the setting, our poor heating and cooling system tries to keep up. I argue that it causes us to waste money. My living room contains 52 kg of air. In the summer time, I pay about $0.15 per kWh of energy used. How much does it cost me every time we heat the air in the living room from 281.0 K to 305.0 K?(HINT: How many kWh does it take?)The heat capacity of our air is 1.01 J/(gC).
