CONCLUSION

RESULTS

TABLE

Construction Light

The water in the blue container increased the most. While the colors magenta, orange and pink maintained its temperature. In the other hand yellow increased at the time of 10 minutes. The black, white and clear containers increased its temperature within 5 minutes. For colors green and purple there temperatures did increase but not like the blue container

More energy was absorbed in the construction light experiment because it was directly pointed at the container. When it comes to whether the color has an effect but seems like it does, depending on the type of light when using an artificial color it tends to have more effect. The color blue absorbed a lot more energy than orange did. When using natural light the color of the container has a small effect as to how the energy was absorbed.

TABLE 2

All the containers were extremely cold but two colors stood above all and this was color white and yellow

INTRODUCTION

PROCEDURE

MATERIALS

STEP 1

The colored containers will be divided into two groups; group 1 will be the light colors- red, orange, yellow, white and group 2 will be the dark colors- green, blue, violet, black

STEP 4

Eight out of nine containers will be painted on the outside with different colors of paint. One jar must not be painted, it will be used as the control variable

Record the temperature and determine the scale of color depending on the absorption of heat.

• 9 containers (8 containers with color and 1 container as the control variable)

• Paint (Red, Orange, Yellow, Green, Blue, Violet, White, Black)

• 80 ml of tap water (for each container)

• High-powered lights

• Calibrated glass thermometers

As we all know, dark colors absorb heat the most than light colors. Light colors reflect more energy than dark colors and absorbed energy is not destroyed as the law of energy states that energy can neither be created nor destroyed but usually converted into heat thus, more absorption of heat for dark colors.

Emissivity is the measure of an object's ability to emit infrared energy. Emitted energy indicates the temperature of the object. Color can affect heat absorption because of emissivity as dark colors absorb all wavelengths of light and is eventually converted to heat while light colors reflect light hence, less absorption.

STEP 2

Each container will contain 80ml of tap water and each group will be tested at a time with the control variable. There will be 5 containers per light, containers must be 20cm away from the light and 3cm apart from each other

STEP 3

The containers will have thermometers in them to monitor the water temperature. Each container will be checked thrice for there temperature for ten minutes. A total of 30 minutes.

OBJECTIVE

> To know which colored container has the highest emissivity or which color can absorb the heat rapidly

> To see which color can radiate heat the fastest by performing independent tests for heating and cooling the colored containers using high-powered lights as the source of heat or energy.
