∙ 10y agoThe mass of a substance in one phase is the same as in another phase because the molecules in the substance just get more or less excited, because you are adding or taking away energy. When you are adding or taking away heat, you are actually adding and taking away energy.

Thusly, phase changes depend mostly on the heat energy (absorbed or released) and the amount of pressure exerted. in a phase change, a substance does one of these things to turn into a different state of matter: melt, freeze, evaporate, boil, condense, sublimate, or desublimate (deposition.)

∙ 13y agoDuring a phase change. the mass of the substance does not change due to the conservation of mass.
In a closed system, the mass does not change no matter what phase change or chemical reaction takes place.

∙ 13y agomass stays the same, however volume changes. If it is going from solid to liquid or liquid to gas, the volume increases. If it is going the opposite direction, then volume decreases. An exception is water, which increases in volume as it goes from liquid to solid.

∙ 10y agoI'm not entirely clear on what you mean by this, but I'll take a stab at it.
If you add heat to a material when it's not at a phase transition point ... to ice at -10 degrees Celsius, for example ... the heat "goes into" raising the temperature of the material. The heat capacity of ice is about 2 J/gK, so if you have a kilogram of ice and add 1000 J of heat energy to it, the temperature will go up by roughly half a degree Celsius.
However, when you reach 0 degrees Celsius, something interesting happens: the temperature stops going up. All the heat added goes into melting the ice rather than raising the temperature. The enthalpy of fusion of water is a little under 500 J/g, so that kilogram of ice will absorb 500 kJ of energy while remaining at the same temperature.
After the ice is melted, the temperature will go up again as more heat is added, at a rate of around 4 J/gK.

Matter that does not change in shape or volume?
A solid has a definite shape and volume.
What happens to the density if you change the volume?
it changes
What state of matter does not change in volume?
Changes in the states of matter - or phase changes - do entail changes in volume.
What is the change in volume from gaseous air to liquid air?
A change in volume is a change in volume - there is no difference. The question, as asked, is therefore meaningless. However if you try to compress air, its volume will decrease (because the gaseous state of matter is compressible). On the other and if you try and compress a liquid the volume will not change as the liquid state of matter is incompressible (that is why/how hydraulic machines work).
Which of the states of matter have mass and volume?
No. Volume can change drastically between different states of matter, especially between solid and gas.
What happens to density of a substance during thermal expansion?
Thermal expansion is the tendency of matter to change in volume in response to change in temperature. During thermal expansion, the density of a substance decreases as its volume increases. Volume is the space occupied by a body. So, when a substance expands on heating, it will occupy more space or will have more volume. But its mass does not change because the amount of matter contained in a body cannot change. Therefore, mass divided by increased volume gives a decreased density.

What type of matter can change shape and volume?
The matter that can change shape and volume is gas.
What happens to the volume of matter when it expands?
It increases.
How does volume of matter change with increase in temperature?
Assuming that pressure and the amount of matter are constant (meaning they do not change), volume will increase as temperature increases.
Matter that does not change in shape or volume?
A solid has a definite shape and volume.
What happens to the volume of the cytoplasm during plasmolysis?
The volume of cytoplasm reduces during plasmolysis
Matter that can change in shape and volume?
gas
What is matter that can change in shape but not volume?
gas
What matter that does not change in shape or volume?
it is a solid
What happens if you change an objects volume?
Expansion means that the volume increases......
