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.
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.
What is the definition of asphalt and macadam?
Asphalt is the crude hydrocarbon, mixed with gravel to become macadam, which is short for its inventor in 1824; John L. MacAdam
Why does the amount of heat from the equator become less?
The amount of heat from the equator becomes less as one moves towards the poles due to the increasing angle of sunlight. Near the equator, sunlight hits the Earth's surface more directly, providing more heat. However, as you move towards the poles, the sunlight is spread over a larger area, leading to less heat per unit area.
How is the viscosity of asphalt cement affected by temperature?
Asphalt cement viscosity decreases as temperature increases. Lower temperatures make asphalt cement more viscous, while higher temperatures decrease its viscosity, making it more fluid. This property is important for paving and construction applications as it affects the workability and performance of the asphalt mix.
Why does the amount of heat receive by places from the equator become less?
The Earth's spherical shape causes sunlight to be spread over a larger area as it moves away from the equator towards the poles. This spread reduces the intensity of the sunlight received, leading to less heat being received in those regions. Additionally, the angle at which sunlight strikes the Earth's surface becomes more oblique away from the equator, further decreasing the amount of heat received.
How does energy become trapped in fuels?
from heat and sunlight
Can your skin become darker by wearing a cast?
no it will only become lighter due to lack of sunlight
What does a seed need to become a mature plant?
Nourishment and sunlight.
What is the best temperature to install asphalt?
The best temperature to install asphalt is typically between 50°F and 85°F (10°C to 30°C). At these temperatures, the asphalt can be properly compacted and achieve optimal adhesion. Installing asphalt in temperatures below 50°F can lead to poor compaction and increased risk of cracking, while temperatures above 85°F may cause the material to become too soft, affecting its durability and finish.
Why are my seedling leaves turning white?
Your seedling leaves may be turning white due to a condition called "sunburn." This can happen if the leaves are exposed to too much direct sunlight, causing them to become bleached and damaged. It is important to provide shade or reduce the amount of sunlight to prevent further damage to the seedlings.
Plants can become unhealthy when?
Plants can become unhealthy when they lack hydration.
