How does density change with increasing temperature?
With few exceptions, density decreases as temperature increases. Density is mass divided by volume. As you heat something up, its volume usually increases. Its density increases on warming from 0 °C to 4 °C and then decreases at higher temperatures.
Does density of mercury change?
Upon freezing, the volume of mercury decreases by 3.59% and its density changes from 13.69 g/cm3 when liquid to 14.184 g/cm3 when solid.
How does temperature affect mercury?
Mercury’s volume coefficient of expansion is 0.00018, so it expands by . 018 percent in volume for every degree of temperature increase. To make the difference easier to see, a mercury thermometer contains a reservoir of the metal and a thin glass capillary into which it can expand.
How does a change in density affect the volume of a mercury sample?
Relating Cause and Effect How does a change in density affect the volume of a mercury sample? Answer: As the density decreases, the volume increases.
Does density increase temperature?
Density changes with temperature because volume changes with temperature. Density is mass divided by volume. As you heat something up, the volume usually increases because the faster moving molecules are further apart.
What is mercury’s density?
5.43 g/cm³
Mercury/Density
The mass and volume of Mercury is only about 0.055 times that of Earth. But because Mercury’s small mass is enclosed inside of a tiny body, the planet is the second densest in the solar system, weighing in at 5.427 grams per cubic centimeter, or 98 percent of the density of our planet.
Does the density of liquid mercury increase or decrease with increasing temperature?
Substance
| Substance | ρ(kg/m3) |
|---|---|
| Water (0°C) | 9.998×102 |
| Water (4°C) | 1.000×103 |
| Water (20°C) | 9.982×102 |
| Water (100°C) | 9.584×102 |
What is the density of the mercury in a thermometer?
13.534 g/mL
Mercury, which is often used in thermometers, has a density of 13.534 g/mL at room temperature.
