Two students wanted to measure the difference in temperature of concrete in the sun and the shade. They place two temperature probes in different spots on a sidewalk, one in direct sunlight and one in the shade. They collected the following data -
Which claim can be made?
Thermal convection requires direct contact to the source of convection.
Radiation can only occur if direct exposure to the source of radiation occurs.
Shade prevents conduction from the sun.
The concrete in the sunlight was warmer due to thermal convection.
What is 2. Radiation can only occur if direct exposure to the source of radiation occurs?
