Respuesta :
According to usual sign convention, thermal expansion creates a negative strain. TRUE
What does thermal expansion mean?
The propensity of matter to vary in volume in response to temperature changes is known as thermal expansion. A substance’s particles move more when it is heated, maintaining a greater average separation. Thermosets experience linear thermal expansion since they are employed in solid form.
What three forms of thermal expansion are there?
The term “thermal expansion” refers to an object’s propensity to change its dimensions as a result of heat, including length, density, area, and volume. The substance’s kinetic energy increases when it is heated.
There are three forms of thermal expansion:
Linear growth.
Area enlargement
Volume increase
What causes thermal expansion?
When an object’s temperature rises, it expands or grows in size, a process known as thermal expansion. Thermal expansion takes place
