The appearance of color is a result of the absorption and reflection of certain wavelengths of light. a shirt appears a certain color because it reflects that color of light. on the other hand, a shirt appears black when it absorbs all wavelengths of light and white when it reflects all wavelengths of light. how will sunlight most likely affect a black shirt on a hot summer day? the temperature of the shirt will depend on how much sunlight is diffracted around the shirt. the temperature of the shirt will not change because the sunlight is transmitted through the shirt to the body. the temperature of the shirt will decrease because most of the light is reflected off of the shirt. the temperature of the shirt will increase because all wavelengths of light are absorbed by the shirt.

The temperature of the shirt will increase because all wavelengths of light are absorbed by the shirt.

Explanation: The different colored objects absorb different wavelengths of light. The appearance of the object depends on the the color it reflects.The black objects appear black as they absorb all the wavelengths of light and do not reflect any color. White objects appear white as they do not absorb any wavelength and reflect all the wavelengths.

Black shirt heat up faster in the sun because it absorb most of the wavelengths of  light while white objects reflect most of the wavelengths of light and thus does not heat.

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂
