RossWhen you heat a cool substance, typically the volume increases while the mass stays constant. This is because heating usually causes the particles in the substance to move faster, spreading out and occupying more space. However, the actual mass of the substance remains the same during this process.

When you cool something down is the mass or the volume changing?
Cooling something down does not generally change its mass, and may or may not change its volume. Cooling a gas will change the volume (if the pressure remains the same). When you cool something down, you most directly change its heat energy.
Sensible heat involves a change in a substance's?
Sensible heat involves a change in a substance's temperature without a change in its phase. It is the heat exchange that causes a change in the temperature of a substance but does not result in a change of state (solid, liquid, gas).
Does water with a greater volume cool faster than water with a less volume?
No, water with a greater volume will cool slower than water with a lower volume because it takes more energy to heat or cool a larger volume of water. The larger volume of water will retain heat longer than the smaller volume.
What are the various properties of a substance that determine its heat capacity?
The specific heat capacity, density, and mass of a substance are properties that determine its heat capacity. Specific heat capacity is the amount of heat required to raise the temperature of one unit mass of the substance by one degree Celsius. Density and mass affect how much heat the substance can store and how quickly it can absorb or release heat.
How does adding or removing heat to a system result in of temperature or change in state?
then the temperature either goes up or down. When you add heat to a substance the substance normally spreads out more for on a subatomic level the atoms vibrate more. Gases have a larger volume at the same pressure and fluids can increase in volume too. Solids normally expand. The opposite to the above is true with a decrease in temperature. It is good to note that if you melt ice it decreases in volume which is proof that heat dose not always expand the substance.
