Most likely it's caused by the fact that supplied heat is transferred to external electronic orbits. When provided some energy external electrons will jump to higher levels which are located farther from nuclei then non-exited. The latter one causes effective radius of atom to increase, in its turn electronic levels of neighboring atoms get closer and in order for the system to be in equilibrium the atoms have to move from each other. As result bodies expend while is being heated.

Why length of spaghetti increase after boiling?

Spaghetti is originally hard and contracted. When heat is supplied to any object, most of them expand. so, when heat is supplied to spaghetti, it expands. However, it is important to note that expansion due to increase in temperature (Thermal expansion) is a very small. So, spaghetti expands only by about an inch.


What state of matter expands with cold and contracts with heat?

Well, solids. For example, when you heat up metal is expands and when you freeze it, it contracts

Does wood expand when exposed to heat?

Yes, wood expands when exposed to heat.


Does the length of spaghetti increase after boiling?

Yes about 1 inch. That's because the spaghetti originally is contracted and hard. And heating normally expands a substance, so when the spaghetti is boiled, the heat supplied causes it to expand a little.


What will happen when heat is supplied to ice?

What is Thermal stress and the effects?

when the temperature of the body is lowered or raised, it contracts or expands accordingly. If this expansion or contraction is prevented, then a stress is produced called thermal stress


Why water expand when it losses heat to turn into ice?

Th water on your body evaporates into the air and since evaporation ... You can experience temperature change due to compression by examining a can of ... your body it feels very cold because the compressed gas expands and loses heat.
