The urban heat island effect is often strongest at night when temperatures would typically drop.  What does this indicate about energy transfer and the material used in the building? (a) The material in buildings releases more energy at night than it absorbs during the day (b) The material in buildings absorbs a lot of energy during the day and when it gets colder at night the energy is released back into the cooler air. (c) The material in buildings absorbs energy during the day and releases it because the temperature of the buildings is lower than the cooler air (d) The material in buildings releases a lot of energy into the hot air during the day so at night all of the energy is still there

First law of Thermodynamics

The word thermodynamics consists of two words: thermo- and dynamics. Dynamics means the study of motion. The field of thermodynamics is all about the study of the movement of heat. In a more meaningful way, it is stated as the study of the transfer of energy. Energy transfer is something that we encounter in day-to-day life. Automobiles, chemical reactions, refrigerators, and power generators work on the basis of thermodynamic principles.
