Why molecules don't have the same speed at particular temperature?
Because at higher temperature, molecules gain energy (Kinetic). THus move faster......
How do you explain the increase in pressure in a closed system when temperature is increased?
Since the temperature is increased, the molecules start moving to and fro... which tends increase in speed of the molecule.. such that the increase in temperature is directly proportional to the speed of the molecules by which the pressure will also increase...
How temperature affects particle movement?
Temperature IS the average speed of movement of the particles molecules that make up an object. The more heat you add to an object, the faster the molecules move vibrate. There are devices thermometers that indirectly measure this speed, and thus report the temperature.
Is it true In a rigid container when the speed of the gas molecules increases the speed of the gas also increases?
It is true that, in a rigid container, when the speed of the gas molecules increases, the temperature of the gas rises. This has nothing to do with the speed or lack of speed of the gas as a whole.
Why does the speed of sound change if the temperature of the medium change?
because the density of the medium changes with temprature
What happens to the temperature and the speed of the molecules when gas is compressed?
The temperature and speed remain constant.
What is the average speed of Hydrogen molecules?
At what temperature? Average speed is the square root of - 8 times the gas constant, times the absolute temperature, divided by pi times the mass of the molecule.
When high speed molecules mix and collide with slower speed molecules the high speed molecules do what?
Slow down and the temperature drops.
Average speed of air molecules?
A thermometer. Temperture is the measure of the kinetic energy, Aka speed, of molecules.
The average speed of the molecules of a gas is proportional to the?
Temperature.
An indirect measurement of the speed of molecules is?
The temperature.
Temperature is an indirect measurement of?
The speed of molecules.
An indirect measurement of the speed of molecules is made with a?
An indirect measurement of the speed of molecules is made with a thermometer.
Does a thermometer give a measure of the size of molecules or the speed?
Temperature.
How did pressure effects the sound when temperature is constant?
The atmospheric pressure has no effect on the speed of sound when the temperature is constant. The air pressure has no influence on the sound.
Why molecules don't have the same speed at particular temperature?
Because at higher temperature, molecules gain energy (Kinetic). THus move faster......
do bromine molecules move faster then air molecules?
The speed of gas molecules is primarily determined by their temperature, not their specific identity. At the same temperature, bromine molecules and air molecules would have similar average speeds.
