What is relation between temperature and molecular vibration of an object?
Heat energy in a substance is the intensity of vibration of the molecules in that substance. The more the vibration more is the heat energy stored in the object. So in a way Heat energy is the kinetic energy of the molecules in the substance. Thus temperature increases on the increase in the kinetic energy of the gases.
Why do you get heat?
Quite simply, heat occurs because the molecules in an object or substance move very quickly. All matter, or substances, contain molecules which are always in a state of motion, and actions such as movement can make the molecules move faster, creating heat. Heat transfers because it is energy which travels in waves, and when it touches something else, the molecules in the new item or substance also become excited, moving faster and faster to create heat.
What is the average kinetic energy of all the molecules in an object called?
The average kinetic energy of the particles in a substance is its temperature.
How do conduction occur?
Conduction occurs when two object at different temperatures are in contact with each other. Heat flows from the warmer to the cooler object until they are both at the same temperature. Conduction is the movement of heat through a substance by the collision of molecules. At the place where the two object touch, the faster-moving molecules of the warmer object collide with the slower moving molecules of the cooler object. As they collide, the faster molecules give up some of their energy to the slower molecules. The slower molecules gain more thermal energy and collide with other molecules in the cooler object. This process continues until heat energy from the warmer object spreads throughout the cooler object.

What is the average amount energy of motion in the particles of a substance called?
A measure of the average kinetic energy of the molecules of a substance or object is simply it's Temperature! Hope that helps.
Where does the heat go when you add a warm substance to ice in a warm room?
Heat is not a "thing," it is not transferred from object to object. Instead, when an object is cold, its molecules vibrate slower than when it is warm. When a warm object comes in contact with ice, the fast-moving molecules of the warm object transfer some energy to the ice. This is why the ice warms up, and the warm object cools off (due to losing some of its molecules' energy).
Do molecules always move?
Yes, as long as the temperature of the substance they comprise is warmer than Absolute Zero.
What is the smallest part of a substance that has all the porperties of the substance?
Molecules are the smallest part of a substance. Molecules have all the properties of a substance.
Will a smaller object always have a smaller mass?
No, it depends on the degree of compactment of its individual molecules or matter.
What happens to kinetic energy of the particles of a substance as the substance changes from a liquid to a gas?
The faster the molecules of a substance are moving, the warmer that substance is, because temperature is really a measurement of the average kinetic energy of the molecules in a substance or object. For a substance to evaporate, or change from a liquid to a gas, it has to become warmer. That means that the kinetic energy of the molecules increases.
Why does an object float in water?
molecules make an object float the airs density has gases that react to substance and then change phase an element has only 1 kind of atom and that atom gets
