Why does conductor heat up when current is passed through after a long time?
Heating up means increase in average speed of atoms oscillation. When current passes through the conductor electrons collide (impact) with atoms and transfer a part of their energy to them increasing their average speed. Error: "average" instead of "average"
Measure of the energy or heat of matter?
The measurement of the energy or heat in matter involves measurement of average speed of atoms and molecules.
How do you find the average speed of an object?
Average distance ______________ = Average Speed Average time
A gas consists of a mixture of neon and argon The rms speed of the neon atoms is 350 What is the rms speed of the argon atoms?
250 m/s
To justify with calculation average speed is equal to instantaneous speed?
Only if speed is constant. There can be no acceleration if the average speed is equal to the instantaneous speed.
In which state will atoms and molecules have the lowest average speed?
Solids.

What determines the speed of the atoms and molecules of a substace?
Temperature is a measure of the average kinetic energy of an object. This is proportional to how quickly the particles move.
How does the spacing and speed of atoms determine a sibstance's state of matter?
In a solid, the spacing of the atoms is the closest, and the speed of the atoms is the slowest. In a liquid, the atoms are farther apart, but still slide past one another, and the speed of the atoms is greater than in the solid, but not fast enough to escape. In a gas, the atoms are far apart and do not affect one another very much, the speed of the atoms is the greatest and the atoms are able to escape the liquid state.
When are speed and average speed the same?
Average speed is an average value of speed over a given time. If your speed is constant (not changing), then your average speed will equal your speed at any given moment in time.
Is average speed the same as speed?
Average Speed is different from average speed becoz speed is particular while avera speed is the total distance divided from time

What is the speed of the atoms in a solid?
Particles in a solid are always moving . They vibrate rapidly about their fixed positions . Their vibration speed depends on the temperature of the solid . The higher the temperature , the faster is the vibration ( movement ) .
Average speed is indicated on the speedometer?
I would call it current speed, not average speed.
Formula for average speed?
average speed = distance / time
