At 25 degrees C the density of water is 1.0 g/mL. If the temperature of the water goes above 25 degrees C the density will drop. If the temperature of the water goes below 25 degrees C the density will rise.
When temperature rises, the density of the medium changes. Speed of light through a medium is inversely proportional to the density of medium. So when the temperature increases, the density decreases and the speed of light in that medium increases. Note that this is the indirect effect of temperature. If light is travelling through vaccuum , then the temperature will have no effect on the speed of light.
yes
Not always. The density of water is 1 gram/mL at around 4 degrees Celsius. As temperature rises, kinetic effects kick in causing the volume per unit mass of water to increase, thus decreasing the density of water. Interestingly enough, the density of ice (frozen water) is also less than liquid water. The formation of ordered crystal lattices occupying relatively large amounts of space causes the rise in volume and an overall drop in density.
The Galileo thermometer is based on a thermoscope designed by Galileo Galilei. There are multiple bubbles filled with different colored liquids and tags that indicate temperature. They sink or rise when their density changes with the temperature of the water around them. The bubble that sinks the farthest is the most accurate temperature.

An increase in air density will mean a decrease in the absorption and radiation of energy. An increase of air density causes temperature and pressure to rise.
Density is mass per unit volume of a substance. The Mass and volume of water is in the ratio of 1:1 .There fore the density of water is 1. With rise and decrease of temperature the volume increases or decreases to change the water density.
yes
With the exception of water, the particles of an object move closer together and become a solid. Being closer together makes the density rise once it becomes frozen but the density won't rise if the temperature is lowered and the object is already frozen. When water freezes, the density lowers, making ice float.
The Earth's mean temperature will rise.
The enhanced greenhouse effect is making air temperatures rise.
If lots of water is added then the temperature will rise
The temperature rise because of the gangnam dance
Remains unaltered
When altitude rises, the air pressure and density both decrease. When temperature rises that means that more air is pushing down on it. So this means that the air pressure and density rise when temperature rises.
