A hotter wire will typically have a higher resistance than a cooler wire. This is because as the temperature of a wire increases, the atoms inside the wire vibrate more vigorously, increasing collisions with free electrons and hindering the flow of electric current, thus increasing resistance.
What else can I help you with?
Would a hot object emit more radiation than a cooler object?
Yes, a hotter object will emit more radiation than a cooler object. This is due to the relationship between temperature and the amount of thermal energy emitted as radiation - the hotter an object is, the higher the frequency and energy of the emitted radiation.
Why a hotter substance cools faster?
A hot substance will pass on heat to a substance at a cooler temperature. If it was surrounded by an even hotter substance it would be "given" heat. Heat can only flow from hotter to colder, just as water flows from higher to lower ground. If the temperature difference between the substances is great, then heat will pass more quickly, but if the difference is very slight, then the flow of heat will be very much slower.
If two objects are the same size but one object is 3 times hotter than the other object the hotter object emits how much more energy?
The hotter object would emit 81 times more energy than the cooler object. This is because the rate of energy emitted is directly proportional to the fourth power of the temperature (Stefan-Boltzmann Law). So, if the temperature is three times higher, the energy emitted is 3^4 = 81 times higher.
What would happen to the current in a simple circuit if a bulb with a higher resistance were used?
If a bulb with higher resistance is used in a simple circuit, the total resistance in the circuit would increase. According to Ohm's Law (V=IR), with an increase in resistance, the current in the circuit would decrease since the voltage supplied remains constant.
What copper wire would have the highest resistance?
A thicker copper wire will have higher resistance as it will offer more opposition to the flow of electrons compared to a thinner wire. Additionally, a longer copper wire will have higher resistance compared to a shorter wire due to increased distance for the electrons to travel. Finally, a copper wire with impurities or defects will have higher resistance than a pure copper wire.
Is the north side of a house hotter than the south side?
No, it would be cooler because the sun is hotter in the South.
Would a hot object emit more radiation than a cooler object?
Yes, a hotter object will emit more radiation than a cooler object. This is due to the relationship between temperature and the amount of thermal energy emitted as radiation - the hotter an object is, the higher the frequency and energy of the emitted radiation.
How does the HR diagram explain why some smaller cooler stars are brighter than larger hotter stars?
In terms of absolute magnitude, a larger hotter star will necessarily be more luminous than a smaller cooler star. However, if a smaller cooler star is much closer to us than a larger hotter star, it may appear to be brighter. None of this has anything to do with the HR diagram.
Why would it be cooler if you climb to a higher elevation in a desert?
it will be cooler because it air pressure decreases as you go higher in space.... DUHHHH!!!!!!!!!

Why is the sun yellowy orange?
The Sun is the colour it is, because of it's temperature. If it was cooler it would be redder, whereas if it was hotter it would be whiter in appearance.
Would A higher albedo result in an overall cooler climate?
Yes, a higher albedo would result in an overall cooler climate. A higher albedo means that more sunlight is reflected back into space instead of being absorbed by the Earth's surface, which would lead to lower temperatures.
Are stars cooler than the sun brighter or dimmer?
Stars can be both cooler and brighter or hotter and dimmer than the Sun, depending on their size and age. Generally, larger and younger stars are hotter and brighter than the Sun, while smaller and older stars can be cooler and dimmer.
Why hotter a substance faster it cools?
A hot substance will pass on heat to a substance at a cooler temperature. If it was surrounded by an even hotter substance it would be "given" heat. Heat can only flow from hotter to colder, just as water flows from higher to lower ground. If the temperature difference between the substances is great, then heat will pass more quickly, but if the difference is very slight, then the flow of heat will be very much slower.
What would you measure to find out which wires have the higher resistance?
current

What plug burns hotter a R44T or R45TS?
The higher number is hotter, so the R45TS is hotter than the R44T. If your heads have tapered seats, then you would need the TS, which is available in the same heat ranges as the T.
