If memory serves me, expansion and contraction can cause stress cracks in many materials, due to breakdown of molecules in
the material.

Does heat cause stress fractures?
This depends on the type of window/glass as some glass is thermally treated. However, stress in the glass from contraction/expansion can make a noticeable crack. Heat alone will not crack glass but it will, over time, melt it.
Why does heat cause expansion?
becuase of the increase in movement of molecules
What are three examples were expansion is a nuisance and explain how the expansion is overcome are accommodated?
Can cause railways to bent. To prevent it,gaps are left along the line
Why do material change size when they change temperature?
The cause is the thermal expansion of materials.
Why does the gas in the refrigerator cause cooling on expansion?
Heat of the gas is lost as work done by the gas.
Do you agree that expansion and contraction only cause problems?
No, we use expansion and contraction to tell temperature(thermometer).
Could expansion or contraction cause problems?
Yes, expansion or contraction of materials can cause problems in structures, particularly if they are not accommodated for in the design. If expansion or contraction occurs unevenly or is not properly controlled, it can lead to issues such as warping, cracking, or failure of the structure. Proper planning and use of materials that can accommodate thermal expansion and contraction is important to avoid these problems.
What are the effects of expansion and contraction?
Expansion and contraction can cause things to crack, as in the weathering of rock. They can cause a bi-metal strip to bend and straighten, which phenomenon is used in some thermostats. Expansion can cause the roadway of a bridge to buckle, so gaps have to be left. Obviously they cause the thread in a liquid-in-glass thermometer to get longer and shorter.
Could expansion when a substance is heated or contraction when a substance is coooled cause problems?
Yes, the thermal expansion is very important in physics and technology.
Why do people wear safety goggles?
Some chemicals and environmental hazards in the area of where safety goggles are required can cause blindness when contacted with the eye. It is same with safety helmets being worn in the construction sites. Eye Protection- Hazards: chemical or metal splash, dust, projectiles, gas and vapour, radiation. Options: safety spectacles, goggles,
Which of theses can cause the expansion and contraction of rocks due to weathering?
Warming during the day, will expand the rock. Freezing during the night, will contract the rock.
What are sfety hazards?
A safety hazard is anything that has the possibility to cause sickness, injury or death. It could be that the method of working, the materials used, or the conditions in which the work is carried out will prove to be a safety hazard.
What are two fibers that cause contraction?
Actin and myosin are two fibers that cause contraction.
Can jewelry and accessories cause food safety hazards?
If they are made of inappropriate materials like lead and cadmium, and are improperly brought into contact with food, especially acidic food, jewelery and other accessories cancreate food hazards.
Can overprotection cause safety hazards when warning signals cannot be heard?
That is always a concern and should be considered whenever selecting hearing protective devices.
What can result from the Expansion and Contraction of objects?
If two materials with different coefficients of expansion are held together (by rivets glue or some other means) and subjected to changing temperatures the resultant stress might cause one or the other or both to fail (break).
What are the safety hazards of food conservation and food additive?
If your food is stored in storage bags or plastic containers, they get spoiled easily and can cause food poisoning when eaten.
