became sag loosen
All balloons expand in heat.
Heat makes overhead power lines expand and hang down into trees and other such things, causing them to short circuit
Being made up of infra red rays which will move in all directions and refract when hitting paticles heat will always expand
YES
Yes
When metals (like the copper in the telephone wires) gets exposed to heat, they expand (thermal expansion) and when the get cooled they shrink. This directly implies that cables are longer in summer when it is hot. So telephone wires are longer in the summer.
Yes as though during the hot days the wires due to the hot heat that make it expand.
They expand with heat.
They expand with heat.
They shouldn't, usually it is the other way around. As with all wire, the temperature effects wire lengths. When wires become warm as in a hot summer day the wires expand and droop and likewise when they become cold as in winter they contract and tighten up. The wires have to be installed to take this condition into consideration. There is a specific engineered sag allowed for each type of conductor from pole fix point to pole fix point.
The metal wires expand in the heat - making them sag.
Due to the thermal expansion of the wiring materials, the wires expand in both width and length. This affects electrical transmission lines, telephone lines, and telegraph lines because of the large space between supporting poles. Example : Copper (Cu) Thermal Expansion= 17.6 μm/m/oC
Heat makes things expand (generally). Therefore railway tracks can buckle because they heat up, expand, and warp. Tire pressure rises because heat makes air expand, too, therefore raising the pressure inside the tire.
All balloons expand in heat.
yes, the heat makes the particles move and in the heat they expand.
the heat expand the solids atoms
