Problem 28DQ

When energy shortages occur, magazine articles sometimes urge us to keep our homes at a constant temperature day and night to conserve fuel. They argue that when we turn down the heat at night, the walls, ceilings, and other areas cool off and must be reheated in the morning. So if we keep the temperature constant, these parts of the house will not cool off and will not have to be reheated. Does this argument make sense? Would we really save energy by following this advice?

Step-by-Step Solution:

Solution 28DQ Step 1 : No, this process would not save energy, as in the morning, due to increase in the heat in surrounding the temperature of the house also increases by conduction process, hence if we use the heater to keep the temperature of the house at normal temperature, it would not save much energy
