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 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).
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.
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.
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.
Density can be altered by changing the mass or volume of an object. Increasing the mass while keeping the volume constant will increase the density, while increasing the volume while keeping the mass constant will decrease the density.

No, the volume of a substance can change when heat is added or removed. Heating a substance can cause it to expand, increasing its volume, while removing heat can cause it to contract, decreasing its volume.
To calculate heat energy when you know volume and temperature, you would need to use the formula Q = mcΔT, where Q is the heat energy, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature. Given volume, you would also need to know the density of the substance to calculate the mass.
Evaporation typically cools a substance because as molecules absorb energy to change from liquid to gas, they take away heat from the surrounding environment. However, under certain conditions such as with evaporative cooling systems, evaporation can be used to cool a substance deliberately.
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).

A substance with a high specific heat will easily change temperature.
A substance with a high specific heat will easily change temperature.
The heat conductivity of a substance does not involve changes to its chemistry. Heat conductivity is a physical change and characteristic to a substance.
No.
That usually means that when you heat a substance, it will expand - its volume will increase.
