Final answer:
To maintain a temperature of 22°C inside when it is 10°C outside, more energy must be expended compared to maintaining a temperature of 13°C inside.
Step-by-step explanation:
In order to maintain a temperature of 22°C inside when the outside temperature is steady at 10°C, you would need to expend more energy compared to maintaining a temperature of 13°C inside. This is because the temperature difference between the inside and outside is greater in the case of 22°C inside compared to 13°C inside.
The amount of energy required to maintain a specific temperature depends on heat flow. Heat flows out of or into a house through its windows, walls, ceiling, and floor. Factors such as insulation, the thermal properties of the materials, and the presence of drafts affect the heat flow.
Maintaining a higher temperature requires more energy because there is a greater temperature difference between the inside and outside. Thus, you would need to expend more energy to keep the inside at 22°C compared to 13°C.
