What does a plastic stopper reduce?
What does a plastic stopper reduce? The vacuum prevents conduction. The tight stopper prevents air from entering or leaving the flask, so convection isn’t possible either. The sealed stopper stops heat getting in by convection; the vacuum stops conduction, and the metal lining between the outer case and the inner chamber stops heat radiating in […]
What are the two main types of steam turbines?
What are the two main types of steam turbines? Two types of steam turbines must be considered, condensing and noncondensing. What is the principle of steam turbine? In simple terms, a steam turbine works by using a heat source (gas, coal, nuclear, solar) to heat water to extremely high temperatures until it is converted into […]

What operates best under bright light conditions? The fovea contains cones that possess high levels of visual acuity and operate best in bright light conditions. What is the process of receiving stimulus energies? The process of receiving stimulus energies from the external environment and transforming those energies into neural energy is called SENSATION. The process […]

What is wave interference and what two types are there?
What is wave interference and what two types are there? There are two types of interference: constructive and destructive. Constructive interference occurs when the wave amplitudes reinforce each other, building a wave of even greater amplitude. Destructive interference occurs when the wave amplitudes oppose each other, resulting in waves of reduced amplitude. What are sources […]
