Why is a black asphalt parking lot feels hotter to your bare feet than a concrete sidewalk does?
A black asphalt parking lot feels hotter to your bare feet than a concrete sidewalk because asphalt has a lower albedo, meaning it absorbs more sunlight and converts it into heat. The dark color of asphalt allows it to retain heat more effectively than the lighter color of concrete, which reflects more sunlight. Additionally, asphalt's composition can trap heat, leading to higher surface temperatures compared to concrete.

Why does black asphalt road become hotter than a white cement sedewalk in the same amount of sunlight?
Black asphalt becomes hotter than a white cement sidewalk by one thing. The reason it gets hotter is because black attracts heat.
Part of the electromagnetic spectrum makes the sidewalk feel warm on a sunny day?
The sun emits all of the electromagnetic spectrum. The part that heats the sidewalk is the infrared region which is invisible and has a long wavelength. Dark objects absorb much more heat than lighter objects so that asphalt pavement will get much hotter than concrete.
Why does a black asphalt road become hotter than white cement sidewalk in the same amount of sunlight?
The darker the color of the road the more sunlight it absorbs. A white cement sidewalk is whiter which absorbs many of the colors making it cooler.
Explain as completely as possible why the asphalt was so much hotter than the concrete?
The concrete, being nearly white, reflected much of the Sun's infrared energy, while the asphalt, being black, absorbed much of the Sun's infrared energy. (Infrared radiation is associated with heat.)
Why does a black asphalt Road come hotter than a white cement sidewalk right in the same amount of sunlight?
A black asphalt road absorbs more sunlight due to its darker color, which has a lower albedo, meaning it reflects less light and absorbs more heat. In contrast, a white cement sidewalk has a higher albedo, reflecting a significant portion of sunlight and retaining less heat. As a result, the asphalt road typically reaches higher temperatures than the white cement sidewalk when exposed to the same sunlight conditions.
When the temperature is 114 F how hot is a concrete sidewalk?
We can change 114 degrees Fahrenheit into degrees Centigrade by first subtracting 32, dividing by 9 and multiplying by 5. That makes 35.5(recurring) degrees Centigrade. That's just about bearable if you run along the sidewalk in bare feet. Some say you might be able to fry an egg.
Does the black top feel hotter than the sidewalk answered on 1 page?

What is hotter blacktop or sidewalk?
Generally blacktop will get hotter because the color black is a better absorber of heat and energy than a lighter colored material. Black is a higher emissivity or rate at which it absorbs energy due to heat. This is why you feel warmer when you wear a black shirt on a hot day compared to a white shirt.
Why does a black aspalt road become hotter then a white cement sidewalk in the same amount of sunlight?
Black asphalt absorbs more sunlight and heat than white cement because it has a lower albedo, or reflectivity. The darker color of the asphalt allows it to absorb more of the sun's energy, which results in higher temperatures compared to the lighter-colored cement that reflects more sunlight.
How much hotter is the temperature above asphalt then it would be over ordinary ground?
Temps over blacktop are 40-60 degrees hotter. I believe it. When we went to Disneyland, the weather report was 80 degrees. If felt like 95-100 in the park. Once we left the park, it was much cooler. The best way to know for sure is to place a weather thermometer over the area.
Would you expect black asphalt or white sand to feel hotter on a sunny afternoon?
Black asphalt would feel hotter on a sunny afternoon than white sand. This is because black surfaces absorb more sunlight and heat up faster than white surfaces, which reflect more sunlight.
Which one is cooler a city or a forest during a hot summer day?
A forest is typically cooler than a city during a hot summer day due to the shade provided by trees, the moisture in the air, and the lack of heat-absorbing concrete and asphalt. The city, on the other hand, can trap heat and experience the urban heat island effect, making it feel hotter.
