Explain how applied heat works between and at critical temperatures

Physics
2 answers:
mafiozo [28]4 years ago

Answer:

Gases become more difficult to liquefy as the temperature increases because the kinetic energies of the particles that make up the gas also increase. The critical temperature of a substance is the temperature at and above which vapor of the substance cannot be liquefied, no matter how much pressure is applied.

Answer:

When a solid substance is heated, its temperature will rise until it reaches a critical temperature. At this point, the item won’t melt unless more heat is provided. This additional heat represents energy needed to change the state of the substance from solid to liquid. This energy loosens the ties of molecules, causing them to move faster. When enough heat energy is provided, the substance will change to the liquid state, but the temperature of the substance won’t change. The amount of heat energy required to change a unit of mass from a solid to a liquid without any change of temperature is the latent heat of fusion. If it’s necessary to increase the temperature of a melted substance, additional heat energy must be provided. The latent heat of vaporization is the amount of heat energy required to change a unit of mass of a liquid to a gas without a temperature change.

To condense a gas to a liquid, the gas must be cooled to the condensation point. After condensation, the liquid will have the same temperature as the gas; the temperature is still at the condensation point. To be cooled further, more heat energy should be released.

Which term best describes the process that occurs when light passes through a lens? A. reflection B. refraction C. resonance D.
Elza [17]
A. Refraction, meaning the same thing...it just passes through. Reflection is when light, heat, or sound bounces off a surface, kind of like an echo. Resonance is sound reverberating, or vibrating. And polarization is the action of not allowing the vibrations of a transverse wave. Hoped this helps you :) 

Short answer: Refraction

The figure below shows regions of the electromagnetic
nika2105 [10]

Answer:

The electromagnetic spectrum in order of increasing frequency is - radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.

The frequency of the gamma rays is >3×10

19

m.

Hence, the gamma rays has the maximum frequency in the electromagnetic spectrum.

Thepotemich [5.8K]
  • C=40cm
  • f=C/2=40/2=20

  • m=3

\\ \sf\longmapsto m=\dfrac{f}{f-u}

\\ \sf\longmapsto 3=\dfrac{20}{20-u}

\\ \sf\longmapsto 3(20-u)=20

\\ \sf\longmapsto 60-3u=20

\\ \sf\longmapsto 3u=40

\\ \sf\longmapsto u=13.3cm

  • m=magnification
  • f is focal length
  • C is radius of curvature
  • u is object distance
