Max Planck observed that if an object is heated to a high temperature, it emits radiation in a way that is related to its temperature. This observation led to the development of quantum theory and Planck's formulation of the quantization of energy levels in a system.

Can gases emit radiation?
Yes, gases can emit radiation. When a gas is heated, it can emit thermal radiation in the form of light. Additionally, certain gases can absorb and emit specific wavelengths of radiation, such as in the process of fluorescence or phosphorescence.
What produces infrared rays?
Infrared rays are produced by the temperature of an object or surface. When an object or surface is heated, it emits infrared radiation as a form of electromagnetic radiation. This radiation is invisible to the human eye but can be felt as heat.
When a warm object is heated up why does the thermal radiation it emits changes?
When a warm object is heated up, its thermal radiation increases in intensity and shifts toward shorter wavelengths. This is due to the increase in the object's temperature leading to a higher average energy of emitted photons, causing the radiation to become more energetic and shift towards the visible spectrum.
What are thermal emitters?
Thermal emitters are materials that emit infrared radiation when heated. They are commonly used in applications such as infrared heaters, night vision devices, and temperature sensors. Thermal emitters can be natural materials like heated metal or synthetic materials designed to emit specific wavelengths of infrared radiation.
Radiation require a heated liquid to transfer energy?
Radiation does not require a medium like a heated liquid to transfer energy. Radiation can transfer energy through electromagnetic waves, such as light or infrared radiation, and can travel through a vacuum. Heat transfer by radiation relies on the emission and absorption of electromagnetic waves between objects.
What is pasterization?
pasterization is where food is heated to a certain temperature to keep it fresh.
If you continue heating a piece of room temperature metal in a dark room what will be its first visible color?
The first visible color of the room temperature metal will depend on the specific metal being heated. Typically, metals start to glow red when heated to a certain temperature. This red color is due to incandescence, where the metal is emitting thermal radiation as it heats up.
When a substance is heated its temperature increases. What other change might be observed?
Ordinarily when a substance is heated it expands. In some cases it melts. In some cases it vaporizes/evaporates.
What type of substance is heated by radiation?
Any substance that absorbs the radiation is heated by it.
Earth's stratosphere is heated by which process?
The stratosphere is primarily heated by the absorption of UV radiation by ozone molecules, leading to an increase in temperature with altitude. This absorption causes the temperature to rise in the lower stratosphere but decreases with altitude due to the decreasing concentration of ozone.
Can gases emit radiation?
Yes, gases can emit radiation. When a gas is heated, it can emit thermal radiation in the form of light. Additionally, certain gases can absorb and emit specific wavelengths of radiation, such as in the process of fluorescence or phosphorescence.
What happens to air heated by radiation?
When air is heated by radiation, the air molecules absorb the radiant energy and increase in kinetic energy, causing them to move more vigorously. This increased motion leads to expansion of the air, resulting in a rise in temperature.
What is observed when zinc nitrate is heated?
it should be heated at 500°c
Is the land heated by convection?
I think the land is heated by radiation
What is mean by preheat temperature in welding?
Some materials have to be heated before you start to weld on them. They will probably have a maximum interpass temperature, and may also need to be kept heated to a specific temperature for a certain amount of time after you stop welding (called post heat).
When Earths surface is heated it radiates some of the energy back into the atmosphere as?
infrared radiation, which is a form of heat energy. This process helps to regulate the temperature on Earth by preventing it from becoming too hot.
What produces infrared rays?
Infrared rays are produced by the temperature of an object or surface. When an object or surface is heated, it emits infrared radiation as a form of electromagnetic radiation. This radiation is invisible to the human eye but can be felt as heat.
