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.
Density will increase. The metal contracts (gets smaller) but will still weigh the same thing.
Yes the volume of ice changes when the ice melts. In fact the volume of ice goes on increasing up to 0 degree Celsius and when the ice melts completely the volume of ice decreases on the contrary. Yes because when ice freezes, it expands and when it melts, it gets smaller.
The water stays cool because of its high specific heat capacity. This means that water can absorb and store a lot of heat before its temperature increases significantly, making it resistant to quick temperature changes.
A physical change is a type of matter change in which the substance's chemical composition remains the same, and no new substances are formed. Examples of physical changes include changes in state (solid to liquid), changes in shape, or changes in size.
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.
density
Changing the mass or volume of an object will alter its density. If mass increases and volume stays the same, density will increase. Conversely, if volume increases and mass stays the same, density will decrease.
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.
If the volume of an object increases but its mass stays the same, the density of the object will decrease. This is because density is calculated by dividing mass by volume, so if the volume increases without a corresponding increase in mass, the density will decrease.
Density is a measure of how much mass is contained in a given volume. It is calculated by dividing the mass of an object by its volume. The relationship between density, mass, and volume can be expressed by the formula: Density Mass/Volume. This means that as the mass of an object increases while the volume stays the same, the density also increases. Conversely, if the volume of an object increases while the mass stays the same, the density decreases.
Density is mass divided by volume, so if mass increases but volume stays the same, then density also increases.
Density = Mass / Volume Therefore: Increase in Mass --> Increase in Density Increase in Volume --> Decrease in Density and Vice Versa.. :) Hope this helped
at constant temperature in a closedcontainer the increase in temperature increases the volume of a gas but not the mass.
The density of an object is determined by its mass and volume. If the mass of the object increases and its volume stays the same, the density will increase. If the volume of the object increases and the mass stays the same, the density will decrease.
If the volume of an object increases, and the mass remains the same, the density of the object will decrease. This is because density is calculated as mass divided by volume, so if volume increases and mass stays the same, density decreases.
If the volume of the object increases while its mass remains constant, the density of the object will decrease. This is because density is calculated by dividing mass by volume, so if volume increases and mass stays the same, the resulting density will be lower.
If the volume remains the same, the density will increase in direct proportion to the increase in mass.
