Does velocity of molecular movement decrease or increase with temperature?
The relationship between temperature and molecule movement is a direct variation. Whenever the molecule movement increases so does the temperature; when the molecule movement decreases so does the temperature. I hope that helps.
What is the increase in the average temperature of the biosphere?
The increase in the average temperature of the biosphere is called global warming.
Why is the average velocity of the molecules in a gas is zero but the average of the square velocity not zero?
The gas molecules are in motion but if the total gas volume is stationary (Eg. closed in a container) the average gas velocity is zero. And since the square of any number is never negative. And not all molecules have zero velocity at a time. Therefore, since not all numbers are zero and no number is negative the the average of numbers should be a positive number and will not be zero.
Why average velocity of molecules of a gas is zero but the square of average velocity is not zero?
It depends on the sign of velocities. For example, if there are two velocities 7 and -7 m/s then the average velocity of the molecules will be 0. But, the square will be 49. The general thing here is that even if a velocity is negative, the square of EVERY velocity irrespective of the sign is positive i.e., squaring always removes the negative sign.
What happens to the volume of gas or liquid s the temperature of a gas or liquid increases?
When heat is added to the system, we increase the average kinetic energy of molecules making up that system. When we increase the temperature, molecules undergo more rapid collisions and therefore takes up more volume. Molecules in solid state of matter has the least kinetic energy.
Why does an increase in temperature increase the volume of a balloon?
This requires one simple equation and then a further understanding of it. PV=nRT where P is pressure, V is volume, T is temperature, n is the number of molecule, R is some constant. From this we can easily see that an increase in temperature does in fact cause an increase in volume. To see why lets think about what temperature is. Temperature is a measure of average kinetic energy. So an increase in temperature increases the average kinetic energy. An increase in average kinetic energy means that average velocity must be increased (K.E = .5(mv^2)). More velocity means that the molecules in the balloon are flying faster, and since pressure is the same, the molecules spread out more, which must increase the volume.
What is the ratio of the average velocity of hydrogen molecules to that of neon atoms at the same temperature and pressure?
3.16:1
Why Things feel hot because?
The sensation of heat is a direct result of an increase in temperature. Temperature is a direct result of the increase in average kinetic energy of molecules.
What is the measure of the average kinetic energy of molecules in the air?
mean free path and RMS velocity .............................................................GHo$t
If you increase the temperature of a gas what happens to the movement of the molecules?
Their average kinetic energy, and hence their speed, increases.
Measurement of average amount of motion of molecules is?
The average amount of motion can be determined by the average speed or velocity of an object. The average speed can be calculated by the total distance divided by the total time. Speed is a scalar quantity. The average velocity can be calculated by the total displacement divided by the total time. Velocity is a vector.
Why temperature in a leaf never rises above 30 degrees even though the air temperature rises much higher than this?
At molecular level I can say that only faster molecules of water can escape due to the effects of force of surface tension. Hence the average velocity of molecules inside the leaf goes down hence temperature which is a measure of average velocity drops or does not rise due to higher outside temperature.
What has a higher velocity helium or oxygen?
At the same temperature and prssure in a gas the helium atoms will on average move faster than the O2 molecules.
What is the movement of atoms in a liquid during a temperature changes both increases and decreases?
As temperature increases, the atoms will move around more energetically - moving on average faster. Translational speeds increase, rotational speeds of the molecules increase, and the magnitude of vibrations of the atoms about their bonds in molecules increase As temperature decreases, the atoms move around less energetically - moving on average slower. Translational speeds decrease, rotational speeds of the molecules decrease, and the magnitude of vibrations of the atoms about their bonds in molecules decrease
How does temp effect the speed of molecules?
Temperature is the average kinetic energy of a set of molecules. Think about that: From physics, you know that the kinetic energy of an object is proportionate to its mass, and the square of its velocity. By adding heat to a system, you are adding energy. That energy is manifested as temperature.
Does temperature affect molecules and atoms?
Yes Temperature does effect the movement of molecules and atoms. This is because the warmer the temperature is the easier the molecules and atoms can move, while on the contrary, the colder the temperature is the more difficult it is for the molecules and atoms move around
Does velocity of molecular movement decrease or increase with temperature?
The relationship between temperature and molecule movement is a direct variation. Whenever the molecule movement increases so does the temperature; when the molecule movement decreases so does the temperature. I hope that helps.
