A wall cavity with a reflective surface has a higher R-value because the reflective surface reduces radiant heat transfer by reflecting heat back towards its source, thus improving the thermal performance of the wall assembly. This can help reduce heat loss in the winter and heat gain in the summer, making the insulation more effective overall.

The albedo of the earth's surface is the fraction of solar radiation that is?
The albedo of the Earth's surface is the fraction of solar radiation that is reflected back into space. It is a measure of how reflective a surface is, with higher albedo values indicating more reflection and less absorption of sunlight by the surface. Land surfaces, ice, and clouds generally have higher albedo values, while oceans and forests have lower albedo values.
Why is the surface temperature of Venus higher than the surface temperatures of the other inner?
The surface temperature of Venus is higher than the surface temperatures of the other inner planets because of its thick atmosphere.
What are cavity back irons?
Cavity back irons are a type of golf club design with a hollowed-out cavity behind the clubface. This design allows for more weight to be distributed around the perimeter of the clubhead, providing forgiveness on off-center hits and promoting higher launch angles. Cavity back irons are popular among beginner and intermediate players for their forgiveness and ease of use.
Double bonds mean higher surface tension?
Double bonds introduce rigidity in the molecule, increasing the attractive forces between molecules and leading to higher surface tension. This increased surface tension allows the molecules to resist external forces and form a more stable surface.
Do small molecules have high surface tension?
Generally larger molecules with stronger intermolecular forces have higher surface tension. This tendency can be seen if you look at the surface tensions of the alkanes. Water is a clear exeption to this pattern due to the very strong hydrogen bonds.

Why are some surfaces more reflective than others?
Some surfaces are more reflective than others because of their smoothness and the material they are made of. A smooth surface allows light to bounce off it more easily, creating a reflective effect. Additionally, materials with higher reflectivity properties, such as metals, will reflect more light compared to materials with lower reflectivity properties, such as wood.
What would be the advantage of the highly branched gastrovascular cavity?
A highly branched gastrovascular cavity would provide a larger surface area for absorption of nutrients and facilitate efficient distribution throughout the organism's body. This would help in digesting food more effectively and meeting the metabolic needs of the organism.
Can a piece if glass reflect more light than a piece of paper?
Yes, glass can reflect more light than paper because it is a smoother and more reflective surface. Glass tends to have a higher index of reflection compared to paper, leading to more light being bounced off its surface.
Will a basketball bounce higher on a flat surface or a rocky surface?
the basketball will most likely bounce higher on a flat surface
The amount of surface brightness a paint or enamel has is called?
The amount of surface brightness a paint or enamel has is called "gloss." Gloss refers to the reflective quality of the surface, indicating how much light is reflected. It is often measured on a scale from matte (low gloss) to high gloss, with higher gloss levels providing a shiny appearance. The level of gloss can affect both the aesthetic appeal and the durability of the finish.
Why is the surface temperature of Venus higher than the surface temperatures of the other inner?
The surface temperature of Venus is higher than the surface temperatures of the other inner planets because of its thick atmosphere.
What does it mean to say that the earth has an albedo of 33 percent?
An albedo of 33 percent means that 33 percent of the sunlight that hits the Earth's surface is reflected back into space. This value is a measure of how reflective the planet's surface is. A higher albedo indicates more reflection and less absorption of solar radiation.
Does water have the highest surface tension?
No, mercury has a higher surface tension.
Does a starfish have a body cavity?
Starfish, or sea stars, do not have a true body cavity like those found in more complex animals. Instead, they possess a coelomic cavity that is filled with fluid and helps in locomotion and feeding. This coelomic fluid aids in their hydraulic system, which allows their tube feet to function. Overall, while they have a cavity, it is not classified as a true body cavity in the same way as in higher organisms.
Why is the surface temperature of Venus higher than the other surface temperatures of the inner planets?
The surface temperature of Venus is higher than the surface temperatures of the other inner planets because of its thick atmosphere.
Does aluminum foil reflect more light than transparent glass?
No, aluminum foil reflects more light than transparent glass. Aluminum foil has a high reflective surface that reflects a higher percentage of light compared to glass, which allows more light to pass through.
