What happens to the particles of an object as the object's temperature rises?
As the object's temperature rises, the particles within the object gain energy and move faster. This increased movement causes the particles to vibrate more rapidly and spread out, leading to an expansion of the object. If the temperature rise is sufficient, the particles may eventually break apart or undergo a phase change, such as melting or boiling.
What happens when a object gains thermal energy?
When an object gains thermal energy, its molecules start to move faster, leading to an increase in temperature. This increase in temperature can cause the object to expand, change phase (from solid to liquid, for example), or even break down if the thermal energy input is too high.
Why does temperature stay constant during a phase change?
To put it in simple terms, all of the energy that would normally increase the temperature of the object, is being used to convert the object from one phase to another. Once the object has completely changed to the new phase, the energy is not needed for phase change and raises the temperature of the object. Because energy is being used to overcome intermolecular forces(apex)
Why doesn't the temperature of an object change if you break the object in half?
It will change. Unless you manage to break it in half without doing any work to it in which case it wouldn't. This is because the energy within the system must remain constant. If you imagine the object existing inside a bubble, all the energy trapped in that bubble must remain the same. So if the object were to spontaneously divide in half without using any energy, the sum of the energy within the two halves must now equal the energy of the whole before it split, so if one half were to magically heat up, the other would now have to cool down to balance the system. Because this is impossible, the only way for the system to remain balanced is for neither half to heat or cool. Therefore there is no temperature change. The other side of the coin is if you were to come from outside the bubble and do work to the object, i.e. break it in half with a hammer. In this case you are imparting energy to the system (hitting it with a hammer) and there has to be a change in the energy of the object. Since we're talking thermal energy, a change in temperature must occur (the object gets warmer). Moral of the story, if you hit something with a hammer it will get warmer.
Can you add thermal energy to an object without increasing its temperature?
Yes, it is possible to add thermal energy to an object without increasing its temperature by changing its phase. For example, when ice is melting, thermal energy is being absorbed to break the bonds between water molecules without a change in temperature.

What happens at the melting point of an object?
At the melting point of an object, it transitions from a solid to a liquid state by absorbing heat energy. The temperature remains constant during the phase change as the solid absorbs energy to break intermolecular bonds and rearrange into a less structured form.
What happens to energy during a phase change?
During a phase change, energy is either absorbed or released as heat without causing a change in temperature. This energy is used to break or form intermolecular bonds between molecules, rather than increasing the average kinetic energy of the molecules.
Did the temperature fluctuate while the is melting?
No. The temperature does not change during the melting process. All of the heat energy is used to break the bonds of the solid to form a liquid, i.e. the energy is used in the phase change, and thus is not used to raise the temperature.
What do you think will happen to the temperature of a substance during a phase change?
During a phase change, the temperature of a substance remains constant. This is because the energy being absorbed or released is used to break or form intermolecular bonds, rather than to change the temperature of the substance.
What if there are no elasticity?
if there is no elasticity means...there will be no deformation in shape and size...and one more thing is if we try to change the shape of the object and no elasticity means the object will break...
What happens to temperature during a phase change?
During a phase change, the temperature remains constant as the substance absorbs or releases heat energy to change from one phase to another. This is because the energy is used to break or form intermolecular bonds rather than raise or lower the temperature.
Why doesnt the temp change at 0 cel even though 80 kcal of heat is added?
At 0 degrees Celsius, added heat is used to break intermolecular forces during the phase change from solid to liquid, not to increase temperature. This energy is known as latent heat of fusion and is needed to overcome the solid's molecular arrangement. Once all the ice has melted, the temperature will start to rise again.
