Why does an object bend when you heat it?
When you heat an object, its molecules start to vibrate more vigorously. This increased thermal energy causes the atoms or molecules to move further apart, leading to expansion. As a result, the object will undergo thermal expansion, causing it to bend or deform if it is not uniformly heated.
What types of physical or state changes can solids undergo?
the solids can turn to liquids by melting and to gas by sublimation
When the temperature of ice cold water is increased slightly does it undergo a net expansion or net contraction?
net contraction
Why a thicks walled glass tumbler cracks on pouring boiling water into it?
The boiling water causes the inside surface of the thick glass to expand rapidly. But the outside of the glass expands at a much slower rate, as it takes time for the heat from the inside to reach the outside, and the expansion to equalise. It is this difference in expansion that can cause the glass to break.
When the temperature of ice cold water is increased slightly dpoes it undergo a net expansion or net contraction?
Contraction for a few degrees Celsius.
Why is the water not used in the construction of liquid in glass thermometer?
water doesnt undergo significant thermal expansion. alcohol expands more when it's heated
Do a very hot summer day railroad tracks can buckle causing train delays and derailments. What is the best reason for the buckling?
the mental rails undergo thermal expansion
How does thermal energy cause substances to undergo chemical change how does thermal energy cause substances to undergo chemical change?
Thermal energy cause thermal decomposition of a compound; the bonds between atoms are weakened.

A star may undergo two or more red giant expansion stages?
true.
What reaction must uranium undergo in order to release energy?
Nuclear fission with thermal neutrons
When the temperature of ice is increased slightly. Does it undergo a net expansion or net contraction?
Net Contraction
What types of physical or state changes can solids undergo?
the solids can turn to liquids by melting and to gas by sublimation
Why small gaps are left between successive rails in railway lines?
In the heat (of summer) the rails undergo thermal expansion. The amount of expansion is proportional to the normal length and, because rails are long lengths of metal, the expansion is sizeable. If there were no gaps then the expanding rails would push against one another until they buckled.

Why aluminium is used in vessels?
because of low its density,high thermal conductivity ant its ability to not undergo sintering when left at stove
