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.

What is happening when direct sunlight heats the sidewalk?
When direct sunlight heats the sidewalk, the concrete absorbs the sun's energy. This energy increases the temperature of the sidewalk by causing its particles to vibrate more rapidly, resulting in the sidewalk feeling hot to touch.
What is hapenned when direct sunlight heats the sidewalk?
When direct sunlight heats the sidewalk, the concrete material of the sidewalk absorbs the heat energy and warms up. This causes the molecules within the concrete to move faster, increasing the overall temperature of the sidewalk. The sidewalk then radiates this heat back into the environment, contributing to urban heat island effect.
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.
Why does a person move forward when he or she pushes on the sidewalk?
When a person pushes against the sidewalk, they exert a force in the opposite direction. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. This means the sidewalk exerts an equal and opposite force on the person, propelling them forward.
Is the sun drying wet on a sidewalk radiation?
Yes, the sun drying wet on a sidewalk is a form of radiation. The sun emits electromagnetic radiation, including infrared radiation, which can heat and evaporate water on the sidewalk.

In the evening snow falls on a cement sidewalk and on a black top playground. which surface will melt the snow faster and why?
The blacktop playground will melt the snow faster than the cement sidewalk. This is because blacktop, or asphalt, absorbs more heat from the sun due to its darker color, which increases its surface temperature. As a result, the heat from the blacktop helps to melt the snow more quickly compared to the lighter-colored cement sidewalk, which reflects more sunlight and retains less heat.
