As the temperature increases, the molecules gain more energy, and they move faster. As a consequence, they tend to move farther apart from each other thus taking up more space/volume. Density is the mass/volume. Since the mass does not change, and the volume increases, the density, in general, will decrease with increasing temperature.

What are two physical properties that can vary even when the substance with these properties does not change?
Density and temperature can both vary for a substance without changing the identity of the substance. The density of a substance can change with temperature, pressure, or the presence of impurities, while the temperature of a substance can change due to external factors like heating or cooling.
Does density change if the sample of the same matter is larger?
No density if a characteristic of matter. Density can vary with temperature and pressure, but a chunk of something twice the volume of another chunk of the same substance will weigh twice as much because the two chunks have the same density.
How can one determine the density of a substance using temperature and pressure?
To determine the density of a substance using temperature and pressure, one can use the ideal gas law equation, which relates the density of a gas to its temperature and pressure. By measuring the temperature and pressure of the substance, one can calculate its density using this equation.
How can one determine the density of a substance when provided with its pressure and temperature?
To determine the density of a substance when given its pressure and temperature, you can use the ideal gas law equation, which is density (pressure molar mass) / (gas constant temperature). This formula allows you to calculate the density of the substance based on the provided pressure and temperature values.
Does a substance change density if it changes physically?
Depends on what you consider a physical change. Substances change their density when they change their state of matter. When the temperature rises, substances usually expand, wich leads to the density decreasing. When the temperature falls, substances contract, increasing the density. Exception would be water, as it shows an anomaly occurring near 273K
What is the only way the density of a pure substance can change?
The density of a pure substance can change by altering its temperature. As temperature increases, most substances expand and therefore decrease in density, whereas as temperature decreases, most substances contract and increase in density.
What are two physical properties that can vary even when the substance with these properties does not change?
Density and temperature can both vary for a substance without changing the identity of the substance. The density of a substance can change with temperature, pressure, or the presence of impurities, while the temperature of a substance can change due to external factors like heating or cooling.
What are the two physical properties that change with temperature?
Density and specific internal energy are two physical properties that change with temperaturea change in temperature.
As long as conditions such as what do not change the density of a substance dose not change?
As long as the temperature and pressure remain constant, the density of a substance will not change. Density is determined by the mass of a substance and its volume, and as long as these factors remain constant, the density will remain the same.
What are 2 physical properities that can can vary even when the substance with these properties does not change?
Density and volume are two physical properties that can vary even when the substance does not change. The density of a substance can vary depending on the pressure and temperature, while the volume can change with the shape or container that holds the substance.
Does density change if the sample of the same matter is larger?
No density if a characteristic of matter. Density can vary with temperature and pressure, but a chunk of something twice the volume of another chunk of the same substance will weigh twice as much because the two chunks have the same density.
How can one determine the density of a substance using temperature and pressure?
To determine the density of a substance using temperature and pressure, one can use the ideal gas law equation, which relates the density of a gas to its temperature and pressure. By measuring the temperature and pressure of the substance, one can calculate its density using this equation.
How can you change density of a substance?
You can change the density of a substance by changing its volume. Density is equivalent to mass over volume. So changing the volume affects density.
What are two physical properties that can vary even when the substance with these properties dose not change?
Density and color can vary while the substance remains the same. Density is mass per unit volume, which can change depending on pressure or temperature. Color can vary due to factors such as lighting conditions or impurities in the substance.
How can one determine the density of a substance when provided with its pressure and temperature?
To determine the density of a substance when given its pressure and temperature, you can use the ideal gas law equation, which is density (pressure molar mass) / (gas constant temperature). This formula allows you to calculate the density of the substance based on the provided pressure and temperature values.
What affects density more temperature or salinity?
Density is affected by both temperature and salinity. The colder the temperature and the saltier the substance, the greater the density.
Which substance has the highest density at room temperature?
Which substance has the highest density at room temperature? hydrogen, oxygen, water
