Thermal lag describes a body's thermal mass with respect to time. A body with high thermal mass (high heat capacity and low conductivity) will have a large thermal lag. : α = Thermal diffusivity (m2/s) Ω = External angular frequency (s−1) L = thickness (m) ==Examples== The slow night-time cooling of a home after its external brick wall has been heated by the sun is one example of thermal lag. Thermal lag is the reason the high temperatures in summer continue to increase after the summer solstice, and it is the reason a day's high temperature peaks in the afternoon instead of when the Sun is at its peak (12 noon). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「thermal lag」の詳細全文を読む スポンサード リンク
