Temperature Effects Density, and Hydrogen Bonds in water, glucose, and alcohol affecting density.
when the temperature is warmer/hotter the molecules in the object are more spread out, less dense.
when the tempreature is cooler/colder the molecules pack together and become more dense, like how ice is cold and solid.
eg. water is spread out, so are the molecules.
water is exposed to cold temperature and turns into ice; hard and dense. molecules packed tightly together. think that they are cold and are huddling together to stay warm.
we can stick our hand in water because we are more dense than water.
but ice is more dense than us, which is why we can't stick our hand through ice. ( that would be so cool...)
the reason water puddles, is because water (H2O) molecules stick together, literally.
alchohol on the other hand, doesn't have a chemical hydrogen bond like water does; hense, alcohol molecules do not stick together.
Glucose, on the other hand, has a very strong hydrogen bond chemical, which is why it's so thick and ALWAYS sticky and stuff.
hope this helps, yours.
i think i just actually helped myself out. i didn't even realize i knew this stuff until i typed it. guess i couldn't put it into words. heh sweet. don't worry, it's def all accurate though.
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.
Temperature, pressure, and common ion effect
Salinity, or saltiness, affects how readily the water changes temperatures as well as its density. Because of this, currents in the water can arise not only from the difference in temperature, but also from the density difference, which comes from the salinity itself.
1 I'm not sure that this is true-- at least without some qualifications. If an object's shape is changed in such a way that it will enclose one or more pockets of air, some other substance, or even vacuum, the object's over-all density may change. If no pockets are formed, then the density probably is not changed 2 Density is the ratio of mass to volume.
It is necessary to indicate the temperature when giving the density of liquids because temperature effects the density of many liquids. For example, water increases in density as it becomes colder.
An increase in temperature results in a decrease in density.
Of course it does.
temperature and pressure
Temperature and Salinity.
time. temperature. candela. electric current.
no, but it does effect the density
Temperature, salinity, and pressure have significant effects on water density. As temperature increases, water density decreases because warmer water molecules are more spread out. Higher salinity increases water density since dissolved ions make the water heavier. Pressure also impacts density, with deeper water being denser due to the weight of the overlying water column.
When you change density and temperature you effect the way sound travels through a medium.
Salinity and temperature both affect water density. As salinity increases, water density also increases because salt water is denser than freshwater. Similarly, as temperature decreases, water density increases due to the water molecules becoming more tightly packed together.
In 3,98°C(The heaviest) the density is 1000 kg/m3 = 1,000 kg/l = 1,000 g/cm3. When going to a higher or lower temperature than 3,98°C, the density decreases.
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.
Speed of sound depends on the density of the medium. As temperature increases density decreases due to expansion in the volume. Hence speed of sound gets affected by the change in temperature. Speed of sound is directly proportional to the square root of the temperature of the medium.
