Assuming mass does not also increase, then density decreases if volume increases.
For example, let's say
Mass= 100 and Volume= 50
Density would = 2
Now, lets increase the volume.
Mass would still = 100, and let's increase the volume to 75.
Density would then equal 1.333...
2 is greater than 1.333.... so yes, density decreases as volume increases.
The mass of an object increases when the volume stays the same and when the density decreases. Thi sis my conclusion.
Density of the object increases.
density
no
Density will increase. The metal contracts (gets smaller) but will still weigh the same thing.
the temp stays the same
What happens to the mass of ice as it melts into water? Nothing. The mass stays exactly the same. Mass can be defined as the amount of matter present in an object, and no matter is added to or taken away from ice as it changes into its liquid state, water. However, interestingly, the DENSITY (or the way the mass is distributed throughout the object, defined as mass per volume or g/mL) does change as ice becomes water. As ice melts to water, its density increases. Another way of looking at it is, as water freezes to ice, its density decreases. This is why ice floats on water! (If this weren't so, the worlds climate and environment would be drastically different -- think of the polar ice caps...) _______________________________________________________________________ But it is true that : ice weighs 0.92 g/mL and water is 1 g/mL so technically there is a difference Thank you George. Just to clarify a minor point, those values you gave aren't weight, but density. Ice doesn't "weigh" 0.92 g/mL, that value is its density. The density of ice is 0.92 g/mL The density of water is 1 g/mL Density is a measurement of the way an objects weight is distributed in a volume. When a block of ice with a certain mass melts into water, the mass of the water is EXACTLY the same. What changes is the volume occupied by the water when the ice melts. So, as far as weight, or mass, is concerned, there still is technically no difference.
As the sea level increases, the atmospheric pressure also increases. Due to the increase in pressure, Gamma radiation (solar heat) gets trapped in the atmosphere after it bounces off Earth's surface. The more radiation that stays in the atmosphere, the warmer our global climate becomes. This will cause more polar ice to melt, sea levels to rise, and more heat to become trapped.
Hot air is less dense than cold air. According to the ideal gas law, PV=nRT (where V=volume and T=temperature) Since all the other factors (P=pressure, n=mols of gas, R=gas constant) remain constant, as you increase temperature you increase volume. Since volume increases, and the mass stays the same, the hot air's density decreases. (Density=mass/volume) Less dense things rise above more dense things, such as alcohol rising above water.
density
If the mass of an object increases while the volume stays the same, the object becomes denser. Density is a measure of how much mass is contained in a given volume, so as mass increases without a change in volume, density increases accordingly.
at constant temperature in a closedcontainer the increase in temperature increases the volume of a gas but not the mass.
Density is mass divided by volume, so if mass increases but volume stays the same, then density also increases.
Density gets decreased as D = M / V Density and Volume are inversely related.
If the volume remains the same, the density will increase in direct proportion to the increase in mass.
the density increases
Pressure increases as volume increases, granted the container stays the same.
When mass increases and volume stays constant, the density increases. When volume increases and mass stays constant the density decreases. When they both change, then the density will depend on the rate of change of mass and the rate of change of volume.
Density increases
Increases.
