When the temperature of a substance decreases increases what happens?
The temperature of a substance increases as the mean random kinetic energy of its particles increases. This is because temperature of an object is directly proportional to the kinetic energy of its particles. Thus when the particles move faster as a whole, such as when the object is put near a flame, the object heats up.
How does the pressure and temperature of each air mass cause changes?
Temperature is really just the amount of kinetic energy in the molecules of a substance. If you add more energy by heating the substance then the molecules dash about faster and faster. This increases the pressure if the substance is constrained, like gas in a jar or in a bomb.
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.
What is the measurement of the average kinetic energy of the molecules of a substance?
temperature is the average kinetic energy of a particle
Average amount of energy of motion in the molecules of a substance?
Temperature!!!!
When molecules in matter spread out as it gains thermal energy?
Temperature is the chief factor in the expanding of molecules in a substance. Temperature creates randomness in a substance, because it increases each molecules energy.
How is the temperature of a substance affected by a change in the average kinetic energy of its molecules?
Directly proportional-- If average KE increases, temperature increases, and vice versa.
What increases the volume of a substance when the temperature increases?
The cause is the thermal expansion of the material; increasing the temperature the molecules become more and more separated each from others.
All the molecules of a substance possess the average kinetic energy value?
This is false not all the molecules of a substance possess the average kinetic energy value. Temperature increases as the average kinetic energy of a gas increases.
What happens to particles as the temperature increases?
As the temperature of a substance increases, its molecules move faster and therefore take up more space. This generally causes a substance to increase in volume when heated.

What happens when the temperature of a substance is increased?
When temperature increases, the volume increases. Firstly, we have to know that volume is refering to the space that matter occupies. When temperature increases, the molecules move vigorously because it receives energy from the heat. There will be more collisions among the molecules that causes the molecules to move to more areas in a medium. Volume therefore increases.
When a substance melts The temperature of the substance increases?
it decreases.
Why may the temperature of a substance change when energy is added?
Thermal energy of a substance is determined by the movement of the molecules and the potential energy of the arrangement of molecules. Heat transfer will stop when thermal equilibrium is reached. It depends upon the substance how long that takes.
