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.

Why doesn't the temperature of an object change if you break in half?
Because the heat is still distributed equally. There is still the same amount of heat.
Does glass break or crack with temperature changes?
When temperatures changes this can cause the molecules in an object to contract [ at low temperatures ] or to expand [ high temperatures ] . Glass is a fragile object and if the molecules in glass contract or expand quickly this can cause the glass to break . [SRM] .
The kinetic theory states that the higher the temperature the what?
Kinetic energy is energy that an object has because of its motion. It states that the higher the temperature of a body the higher kinetic energy of its particles.
Why glass breaks due to temperature change?
Glass isn't really a solid - it's a 'super-cooled liquid' - sudden temperature change causes 'thermal shock' where the outer surface expands or contracts quicker than the rest of the glass - causing it to break.
Why does the temperature not change during a phase change?
During the change of state, the molecules of a substance absorb energy to overcome the strong intermolecular force of attraction between them. Hence the heat energy which we supply is absorbed by them for this purpose. So change in temperature is not observed.

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 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...

How does a sudden change in temperature break up rock?
in cold countries,water freezes inside cracks of rocks,expands,and causes rocks to break.
What can break chemical bonds of atoms?
A chemical reaction can break the chemical bonds that hold atoms together. A change in temperature can also do it, as can an electric current.
Why does temperature no change during energy phase change?
During a phase change, the heat transferred to a substance is used to break intermolecular forces (latent heat), and thus the temperature of the substance does not change. The opposite also occurs: heat is transferred from a substance during a phase change without a decrease in temperature as intermolecular bonds form.
How can you break a glass without touching it?
There are many ways to break glass without touching it. Here are a few methods: To do it with sound you need a sound that is a resonant frequencies of the glass you want to break. A sound that is the right frequency with enough volume will put energy into the glass and break it. Glass is one of the easiest materials to break using sound although any object can be broken using sound. A high enough air presure difference on glass surface will cause it to break. This is why they say to open windows when there is a tornado. Electricity at a high enough power can also break glass but it must overcome the non-conductive nature of glass before it will break. Even once you overcome the non-conductive nature of glass the heat generated by the electricity is what truly breaks it. Rapid temperature change (hot or cold) is the most common ways that glass is broken without any object touching it. A safe experiment using temperature to breaking an object: Place an ice cube into a container of warm water (do NOT use hot water). As soon as the ice enters the water you will hear the ice pop and crack due to the rapid temperature change breaking the ice.
