hi! no the current squared is directly proportional to the change in temp, Joules Law
A short thick copper wire at low temperature would have lower resistance compared to a long thin iron wire at high temperature. This is because resistance is inversely proportional to cross-sectional area and directly proportional to temperature and length of the wire. The short thick copper wire has a larger cross-sectional area, which results in lower resistance.
The amount of radiation emitted by a hot body is directly proportional to the fourth power of its temperature (Stefan-Boltzmann law). Therefore, if the temperature of a hot body is increased by 50 units, the amount of radiation emitted will increase by a factor of (1+50/old temp)^4.
The speed of sound is directly proportional to the square root of the temperature of the medium. This relationship exists because higher temperatures lead to faster molecular motion, resulting in an increase in the speed at which sound waves can travel through the medium.
The pressure and temperature relationship is described by the ideal gas law, which states that the pressure of a gas is directly proportional to its temperature when volume and amount of gas are kept constant. This relationship can be expressed as P ∝ T, meaning that as temperature increases, pressure also increases proportionally.
A low temp source emits low-frequency, long wavelength waves. A medium temp source emits medium frequency, medium wavelength waves. A high temp source emits high frequency, short wavelength waves.
Neither. The relationship is not that simple.
If you have an electronic Thermostat, make sure that you are changing the "Program" and not just setting the "current" temp. Most electronic ones will change the temp NOW but will change back to the program after a set amount of time.
it has many temp because it can be changed by a reaction of the change in temp

i change the thermostat and the temp switch but still not working
Change in temp=final temp-initial temp, so -5-15=-20 lrn to math
It will bring a cool current Because it flows from the equator towards the pole
