A student may say hypothesis that the water on the outside of the paint evaporate faster than the inside . Describe an investigation of the student could use to test this hypothesis

First of all, exterior paint is more resistant to extreme temperatures, humidity, pressure differences, the presence of droughts and this is due to its chemical composition, which is more resistant and because it penetrates the surface to be painted better (than in This case is the external wall of a home), by better penetrating the surface to which it is applied, there is less risk of detachment, of accumulating bubbles or air at the wall-paint interface, it adheres much better ... as explained this? Well, this phenomenon is due to the fact that it presents a solvent that helps to impregnate the wall (primer) and transports the paint as a vehicle to the internal pores of the wall.

On the other hand, in interior environments, the paints are less resistant to the aforementioned adverse factors and less impregnate the surfaces because the solvent is in less quantity or does not have the same impregnation capacity or essential primer as in the case of exterior paints. .

Explanation:

There are some specialists in the field who nowadays advise even interior paints with insulating or waterproof lacquers since the interior ones bear so little factors such as humidity that they no longer meet the basic requirements, that is why some interior paints they show fungus or wet stains against walls with wet content.

Water on the outside of the paint evaporate faster than the inside. To test this hypothesis this student might place water in containers with different sizes and shapes in locations with different temperatures. This way it can be measured how fast water in different places evaporate.

Explanation:

A change in temperature can affect the  physical properties of water.  Water circulates through a continuous  cycle.  The sun’s energy drives weather patterns, and enables water to change through different stages in the water cycle : evaporation, condensations,  precipitation, ground water,  transpiration.

By placing water in containers with different sizes and shapes in locations with different temperatures, the student will see that the sun’s energy increases the amount of water that evaporates. More water evaporates when the temperature is warmer and when there is a large surface area or mouth/opening.

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
