Questions on Temperature and Movement - Akapink

[akapink]

i recently watched a documentary and they said that the temperature during the big bang was billions of degrees. Could that be true? Does this mean that temperature doesent have a limit like let's say it can't go beyond a certain number? also does it have any point of minimum value ?

also i have been contradicting with some guy over a question. i told him that in every object there is movement ( at a microscopical level atlest, the atom) , even in a cup of tea or in the pillow of his bed. am i right or wrong ?

thanks, akapink

You are completely correct.

At the very least, any object that is warmer than absolute zero must have some kinetic energy in it. And there is no such thing as an object that is at absolute zero.

ty. this is what i found about the temperature so far

Temperature is on an infinate scale, starting from 0K and going up infinately far. Reason being that although there is a limit to how much energy you take out of something, there is no limit to how much you can put in. However, the speed of the object due to extra Kinetic Energy/Heat Energy or whatever has an asymptote with the speed of light becuase the object's mass increases too.

I can confirm that the temperature during the big bang was estimated to be billions of degrees. This is based on observations and mathematical models of the early universe. However, it is important to note that the concept of temperature as we know it today may not have existed in the same way during the big bang. The extreme conditions of the early universe may have altered the fundamental laws of physics, including our understanding of temperature.

In terms of whether temperature has a limit, it is currently believed that there is a theoretical maximum temperature called the Planck temperature. This is estimated to be around 1.4 x 10^32 kelvin, beyond which the laws of physics as we know them break down. However, this is still a topic of ongoing research and there is much we still do not know about extreme temperatures.

Regarding your question about minimum temperature, there is a theoretical minimum temperature called absolute zero, which is 0 kelvin or -273.15 degrees Celsius. This is the point at which all molecular motion stops and is considered the lowest possible temperature.

As for your question about movement in objects, you are correct that even at a microscopic level, there is movement in all objects. This movement is caused by the thermal energy of the atoms and molecules that make up the object. So, in a sense, everything is constantly in motion. This is known as Brownian motion and was first observed by the scientist Robert Brown in the 19th century.

I hope this helps answer your questions and clarifies any misunderstandings about temperature and movement. Science is a continuous process of learning and discovery, so it is natural to have differing opinions and ongoing debates. Keep asking questions and seeking answers!
