At which temp does a water sample has the highest average kinetic energy?
The answer would be 25 ml of water at 95 degrees Celsius. Temperature is the usual kinetic energy of the material that it measures, therefore the highest temperature selection.
Which temperature represents the highest average kinetic energy?
Use absolute temperatures in Kelvin. => 27°C + 273.15 = 300.15 K. Then, the highest temperature is 27°C and that represents the highest kinetic energy.
At what temperature is the average kinetic?
The Kelvin temperature of a substance is directly proportional to the average kinetic energy of the particles of the substance. For example, the particles in a sample of hydrogen gas at 200 K have twice the average kinetic energy as the particles in a hydrogen sample at 100 K.
In which sample do the particles have the highest average kinetic energy *?
gas particles
Molecules in the solid phase have the least amount of energy, while gas particles have the greatest amount of energy. The temperature of a substance is a measure of the average kinetic energy of the particles.
Which sample of ethanol has the highest kinetic energy?
the answer is two. All you are looking for with highest average kinetic energy is the one with the highest temperature. In this case it is 10mL ethanol at 55 degrees Celsius.
What expression defines the change in free energy?
The change in free energy is the difference between the change in enthalpy and the product of the Kelvin temperature and the entropy change. This relationship can be stated mathematically as DG = DH – TDS.
Which gas has the highest average kinetic energy?
Nitrogen and helium, at 100°C , have the highest average kinetic energy because they have the highest temperature.
Is kinetic energy directly proportional to temperature?
The average kinetic energy of gas molecules is directly proportional to absolute temperature only; this implies that all molecular motion ceases if the temperature is reduced to absolute zero.
Does kinetic energy increase with temperature?
When the temperature of an object increases, the average kinetic energy of its particles increases. When the average kinetic energy of its particles increases, the object’s thermal energy increases.
Which sample of matter has the greatest distance?
Explanation: At standard temperature and pressure, gases have the greatest distance between their molecules. Gases are the most random state of matter of all the three known state of matter.
In which state do the molecules of water have the highest average kinetic energy?
If you are talking about its state, then a water molecule that is in its gas state has the highest kinetic energy.
Which beaker has the highest kinetic energy?
Beaker C. The thermal energy of the water increases with temperature and with the number of molecules. Because beaker C has the highest temperature and as much water as any other beaker, it has the most thermal energy.
Which is temperature represents the highest average kinetic energy?
Which temperature represents the highest average kinetic energy of the particles in a sample of matter? Which sample of water contains particles having the highest average kinetic energy? At standard pressure,during which physical change does the potential energy decrease? which sample of matter has a crystal structure?
Which is sample of water contains particles having the highest kinetic energy?
Which sample of water contains particles having the highest average kinetic energy? At standard pressure,during which physical change does the potential energy decrease? which sample of matter has a crystal structure? which element has a melting point higher than the melting point of rhenium?
How much heat is needed to melt 200 grams of H2O?
What is the amount of heat required to completely melt a 200.-gram sample of H2O (s) at STP? what is the amount of heat in joules required to increase the temperature of a 49.5 gram sample of water from 22 degrees celcius to 66 degrees celcius?
Which is statement describes the initial flow of heat?
A cube of iron at 20 degrees celsius is placed in contact with a cube of copper at 60 degrees celsius.Which statement describes the initial flow of heat between the cubes? 1)heat flows from the copper cube to the iron cube. 3)heat flows in both directions between the cubes.
