Temperature affects paint consistency, drying time, appearance and durability. Recommended temperature ranges vary between brands, and manufacturers list this information on their packaging. Paints, varnishes and sealants work best when applied and left to dry at an acceptable temperature.
As temperature increases, the density of liquids and gases decreases; as temperature decreases, the density increases. Density is the amount of mass per unit of volume.
Given the same temperature and pressure, humid air rises compared to dry air. As the humidity increases, so does the tendency of air to rise.
Large bodies of water will impact the temperature by releasing energy slowly and absorbing heat from the Sun, which cools areas that are near large bodies of water and moderates the Earth's temperature. The process begins with with the Sun's energy and the radiation that comes off of the Earth's sur
Temperature either raises or lowers the pH of a solution. If the temperature increases, the pH typically lowers. If the temperature decreases, the pH typically increases.
Temperature affects the speed of sound by changing the density of the medium in which a sound wave travels. In most cases, when the temperature of a medium increases so does the speed of sound through that medium.
Physical activity increases body temperature; increased body temperature raises metabolism. A person who is exercising burns more energy (or calories) than someone sitting at a desk.
Air temperature decreases as altitude increases. Air is a mixture of gases, and at higher altitudes, air pressure decreases, which cools any gas. Air pressure on Earth is estimated to be about 14.7 pounds per square inch at sea level.
The darker an object is, the more efficiently it absorbs radiation and the hotter it becomes. Conversely, hotter objects emit light of shorter wavelength. Objects with sufficient thermal energy glow visibly red, yellow, white then blue.
Relative humidity inside a greenhouse can be accurately measured using a sling psychrometer. Other devices include humidity pocket meters, humidity pens, hydrothermograph and humidistat, which measures relative humidity within a 4 percent precision level.
