Heat absorbtion and Lights effect on Paint

Heat absorption:As heat energy reaches an object it can be absorbed in

a similar manner to the way sponges absorbe water.Heat enters an object

warming it. The larger the object is exposed to the heat source the more heat

it absorbes.

Different objects absorb heat at diffrent rates .some objects are excellent absorbers,

while others are very poor absorbers.

Generally, dark colored objects or materials absorbed

better than do lighter colors.

Lots of factors affect the way an object absorbs heat the type of material it is made out of ,what

color it is ,and what kind of texture it has.

Every material has a set of properties that lets it absorbs some frequencies of light and reflect others.

Three things can happen to light when it hits a meterial,

It can be reflected, as in a mirror.It can be

transmitted,as with windowglass.Or it can be absorbed and turned into heat.

Heat and color or light ,are two diffrent forms or energy, however,the two are related as light energy is

converted intoheat energy when light hits an object.

Simply put,the more light energy that is absorbed,

the hotter an object becomes.

Colors affect the absorption of heat. Dark colors (black,red ,dark blue absorbe more heat thanlight colors

(white, yellow, light pink).

Light +shadow can have a profoundeffect on how we perceive materials. the direction and type of light affects

how a materials surface texture appers.the color of light effects how colors appear.

Heat is a form of energy.It can be produced from other forms of energy.The sun provides us with both light and

heat.The amount of heat an objects absorbs depends on what it is made of, and what color it is.

Heavy, dense objects like brick walls and rocks take longer to heat up but also take longer to cool down, so they

act as insulation.Dark colored things also absorbe more heat than light colored things.

Shiny things reflect more light away, so do not tend to get as hot. Color plays a role in heat absorption.Dark colors

absorb heat. Light colors reflect it.

It is a known fact that all objects give off energy. At the same time all objects takes in energy,too.the color of an object

affects what color of light the object gives off and what it absorbs.

The color of an object relies on the wavelengths of colors reflected colors absorbe comparatively more light .Since light

is energy,an absorption would increasea materialstemperature. Hence, darker colors become better radiators of heat.

There fore from my research i found heat absorption affect materials according to ;

1.where the heat is absorbed.

2. what is absorbing the heat.

3. how moch heat it being used or put out.

where as lights affect on materials dependon :

1.the surface area of materials (rough or smooth )

2.color of material.

3.temperature

Light and shadow can have a profound effect on how we perceive materials.

The direction and type of light affects how a material's surface texture appers.

The color of light effects how colors appear so when choosing materials and colors consider how they will appear under the diffrent

lighting.Conditions in which they will be seen including time of day amount of cloud cover and both natural and artificial lighting.

hypothisis:i think temperature changes will affect the paint do to lights affect on materials and heat absoption and many other factors that can affect it.
Controlled Variables: Type of paint Amount of heat Whare the paint is placed How much paint

Independent Varibles: change in the temperature

Dependent Varible: the paints texture and consintisy will change
