Why does some tungsten erosion occur?
Tungsten erosion can occur due to high temperatures and mechanical forces that cause the tungsten to degrade over time. This erosion can be exacerbated by factors such as the presence of impurities in the environment, high energy particle bombardment, and repeated heating and cooling cycles. Ultimately, these factors can lead to the degradation and loss of tungsten material from the surface.
What is a rigid brittle rock called?
A rigid brittle rock is called a "fault rock". This type of rock typically forms along fault lines due to the intense pressure and tectonic forces acting on it, leading to its rigid and brittle nature.
What Causes of stresses and forces to which a ship exposed?
motion & waves
What kind of force to which fasteners are often exposed?
Fasteners are often exposed to tensile forces, which are forces that stretch or pull the fastener in opposite directions. These forces are generated when the components being fastened experience external loads or vibrations. It is important for fasteners to be able to withstand these forces to maintain the integrity and stability of the joint.
Are ionic compound brittle?
Yes, most ionic compounds are brittle because their structure is held together by strong electrostatic forces between positively and negatively charged ions. When a force is applied to an ionic crystal, these forces can cause the crystal to shatter rather than deform.
Why does the newly formed magma at divergent plate boundaries rise to the surface?
Interior pressure of the forces the magma through the crack. This upwelling of magma then rapidly cools and becomes brittle as it hardens. The pressure of the subsurface magma then breaks this brittle rock and forces more magma up in a continuous cycle.
Is the ionic hard brittle or soft?
Ionic compounds are typically hard and brittle due to their strong ionic bonds. The ions in an ionic compound are held together by strong electrostatic forces, making them rigid and resistant to deformation.
Ionically bonded compounds tend to be brittle?
Yes, ionic compounds are brittle because the strong electrostatic forces holding the oppositely charged ions together do not allow for much flexibility or deformation when a force is applied. This leads to the ionic lattice easily breaking apart under stress.
Why are substances made up of ion brittle?
Substances made up of ions are brittle because the ions are arranged in a regular lattice structure that can be easily disrupted by external forces. When a force is applied, the ions can shift positions and break the structure, leading to the substance breaking or shattering.
Why are ionic solids hard and brittle?
Ionic solids are brittle and hard as they are bonded with electrostatic bonds.
Physical or chemical changes that occur in exposed crustal material through the activity of the forces of nature is?
erosion
Explain the role of Van der Waal forces in PVC plastic rubbers?
van der waal forces provide an extra blnding force between the chains of the polymers. this makes pvc relatively more brittle
