When energy changes forms energy is always produced?
No, energy is not produced. The total amount of energy doesn't change.
How the thermal energy of an object changes when the objects temperature changes?
when abody is heated definitely its thermal energy increases so far that it can even cause a change in its physical appearance
What gives wind its energy?
From changes and or differences in temperature and pressure, ultimately, caused by regional differences in distances from the sun and a continuous change in distance from the sun as the globe spins.Wind is created as the pressure or temperature changes.
Why does temperature stay the same during a phase change?
The temperature, in Physics, means the measure of Kinetic Energy in a substance. When a substance is either heated or cooled, Kinetic Energy is either being added to taken away from the substance. When the amount of KE in the substance changes, the temperature change. However, when the substance is changing its state, because all the KE change in the substance is being used up to change the state, the temperature will not change. When the substance is changing state, the KE can be measured by calculating the heat of fusion and heat of vaporization.
When energy enters a substance what is it called?
The electrons of different atoms start moving due to the change in kinetic energy. This produces a rise in the temperature of the substance. Each substance will have different reactions to the temperature changes{THIS WAS NOT MY ANSWER}
When energy changes forms energy is always produced?
No, energy is not produced. The total amount of energy doesn't change.
What particle property changes with change in temperature?
A change in temperature leads to a change in the kinetic energy of the atoms in the particle.
Does a chemical change create a temperature change?
Almost all chemical changes release or take in energy, and thus do result in changes in temperature.
What is unique about temperature during phase changes?
It doesn't change notwithstanding heat energy changes.
What changes in an exothermic chemical change?
A change that releases energy in the form of heat to its environment.
What During a phase change the temperature of a substance .?
The temperature* remains unchanged. * The heat (energy) content changes.
Does the temperature change if the average kinetic energy of a substance changes?
When Ave KE increases temperature increases.
Changes in which no new kinds of matter are produced is called?
A chemical change. Chemical changes can also be indicated if energy is given off. Physical changes on the other hand do not produce energy or produce new substances.
When matter changes can it absorb heat energy or release heat energy without a corresponding change in temperature?
no.
Explain Why physical changes can be reversed but chemical changes cannot?
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.
What happen to the temperature of a substance during a phase change?
The temperature* remains unchanged. * The heat (energy) content changes.
What happens to the temperature during a phase change?
