Why does lime expand and get hot when water added to lime?
When water is added to quicklime (calcium oxide), it undergoes an exothermic reaction to form calcium hydroxide (slaked lime). This reaction releases heat, causing the lime to heat up. Additionally, the rapid formation of calcium hydroxide leads to an increase in volume, causing the lime to expand. This combination of heat and expansion can create a vigorous reaction, which is why caution is advised when adding water to quicklime.
What does matter change into if heat is added?
Heat makes most things expand. Or in other words, heat makes matters less dense.(With the very known and remarkable exception of water, ice which will decrease in size when it becomes water and becomes more dense until it reaches 4 degrees Celsius, from which point on it will expand again.)Heat can make matters change state.Ice (solid) into water (liquid), water (liquid) into steam (gas).
Is water have specific heat at constant volume or not?
Yes it has! the specific heat of water at constant volume is given by cV : Heat capacity at constant volume cP : Heat capacity at constant pressure : Thermal expansion coefficient : Isothermal compressibility : Density
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.
Does heat make gas contract or expand?
Being made up of infra red rays which will move in all directions and refract when hitting paticles heat will always expand
What is an increase in volume that occurs when heat is added to a substance called?
An increase in volume that occurs when heat is added to a substance is called thermal expansion. This happens because the particles within the substance gain kinetic energy and move further apart, causing the substance to expand.
How does the volume of material chage as more heat energy is added to it?
Most substances expand as their temperature increases. One exception that I can think of is water, when it is near freezing. Water at 4°C will expand when cooled to 0°C, then as it freezes to ice it expands. This is why ice floats in water.

What happens to the volume when heat is added?
When heat is added to a substance, its particles gain energy and move more vigorously, causing the substance to expand and increase in volume. This is because the increased energy disrupts the forces holding the particles together, allowing them to spread out more.
Does the volume of a substance remain the same when heat is added or removed?
Usually the volume changes - only a small amount for a solid or liquid, quite a lot for a gas. For an "ideal gas", the volume doubles when the temperature (absolute temperature, expressed in kelvin) doubles.
Do water atoms expand or multiply when heated?
Water atoms do not expand or multiply when heated. When water is heated, the heat energy causes the water molecules to move faster and farther apart, which results in the expansion of the water volume. The number of water molecules remains the same.
Do liquids expand?
Yes. liquids expand. If we heat the beaker which is filled with water using a candle, the volume will rise as the water is mixed with hot air. Hot air would want to excape, therefore liquids do expand.
Does sea water expand when heated?
Yes, sea water expands when heated because the heat causes the water molecules to move faster and spread out, increasing the volume of the water.
What is the expansion meaning of eta?
That usually means that when you heat a substance, it will expand - its volume will increase.
Why do substance s expand when energy is added to them as heat?
When heat is added to a system, it increases the kinetic energy of the molecules. Increased K.E in system causes molecules to move further away from each other. This causes system to increase in volume. Significant increase in volume might not occur but at microscopic level it definitely changes.
What would increase the volume of gas?
heat causes gases to expand
What would increase the volume of a gas?
heat causes gases to expand
