When heated up, things change temperature. Differences are measured as specific heat. Difference is explained in the unit of measure. Materials that change temperature quickly (low specific heat) can transfer the heat quickly. This is called... 1. Conduction Energy transfer by the collision/vibration of molecules. A person at the beach burns their feet in the sand, and runs to the water for relief. Why does the sand at the beach heat up faster than the water on a hot summer day? a)Water is a darker color than beach sand b)Water has a higher specific heat than beach sand c)Beach sand receives a greater angle of insolation d)Energy is evenly distributed 2. Convection energy transfer through density changes in a fluid. 2. Convection energy transfer through density changes in a fluid. 2. Convection energy transfer through density changes in a fluid. The diagram shows a box used to demonstrate the process of convection in the atmosphere. Which diagram has arrows that show the direction of airflow that occurs when the candle is burning? 1) 2) 3) Density changes Contact with moving atoms Waves through space
