Do molecules at the same temperature have the same speed?
The average speed (actually: kinetic energy) of molecules/atoms is directly related to temperature. So, if the temperature is the same, the average speed of the same molecules is the same, independent of the state.
Do all molecules of the same substance at the same temperature have the exactly the same thermal energy?
Because temperature is an average of the kinetic energy of the molecules, it does not depend on the amount of the substance. So if one object has few molecules with a high temperature, it may have the same thermal energy as another object that has many molecules at a lower temperature.
Do all molecules have the same high or low temperature limit?
Yes. At any given instant, there are a range of values of molecular speeds in a sample of gas. Any single molecule can speed up or slow down as it collides with other molecules. The average velocity of all the molecules is constant at constant temperature.
How is temperature relate to kinetic energy?
Another way of thinking about temperature is that it is related to the energy of the particles in the sample: the faster the particles are moving, the higher the temperature. That is, the average kinetic energy of a gas is directly related to the temperature.
Do all the materials have the same temperature?
If you leave metal and wood in contact, without major energy flow to or from other things, they’ll come to the same temperature. That’s true for any materials. However, they won’t feel like the same temperature, because the metal has higher thermal conductivity. If they’re hot, the metal will feel hotter.
Do all of the substance at a certain temperature move at the same speed and in the same direction?
If you compare different substances that are at the same temperature, then the average kinetic energy of the particles will be the same (i.e. if the particles have the same mass then they will move with the same speed), but the attractive forces in solids will be greater than those in liquids, which will be greater …
Can two objects made of the same material at the same temperature have different amounts of heat?
Identical masses of different materials can have different amounts of thermal energy, even at the same temperature. This means that the material that makes up the substance is a third factor that affects how much thermal energy a substance has.
What happens when two things have the same temperature?
When two objects are in thermal equilibrium they are said to have the same temperature. During the process of reaching thermal equilibrium, heat, which is a form of energy, is transferred between the objects.
How do particles move at high temperatures compared at low temperatures?
With an increase in temperature, the particles gain kinetic energy and move faster. The actual average speed of the particles depends on their mass as well as the temperature – heavier particles move more slowly than lighter ones at the same temperature.
How does temperature relate to kinetic energy of molecules?
What is the melting point of a liquid in a thermometer?
The two common liquids used in liquid-in-glass thermometers are alcohol (ethanol) and mercury, which have melting points and boiling points of -114^oC, 79^oC and -39^oC, 357^oC, respectively. Would…
What is the temperature at which Oxygen condenses into liquid?
Oxygen condenses into a liquid at approximately 90.2 K. To what temperature does this correspond on both the Celsius and the Fahrenheit temperature scales?
What is the rate constant of chemical reaction at 30 degrees Celsius?
At 30 degrees Celsius, the rate constant is 0.0140 s-1. At what temperature (in degrees Celsius) would this reaction go twice as fast? Why does a tile or wooden floor feel colder than a carpeted floor when both are at the same temperature? (assume both below room temperature) Which would feel hotter if they were at the same tempe…
What is the temperature of a solution in a reaction flask?
An organic chemist measures the temperature T of a solution in a reaction flask. Here is the result. T= 82^oC Convert T to SI units. Round your answer to 0 decimal places.
