What else can I help you with?
At which temperature would the molecules in a one gram sample of water have at the lowest average kinetic energy?
5 k
What happens to a sample of matter when its particles lose kinetic energy?
A loss of kinetic energy in the atoms or molecules of a sample of matter will result in the cooling of the sample. That sample will get colder as remove thermal energy from it. The atoms/molecules of a substance have kinetic energy associated with them. This kinetic energy is the result of atomic and/or molecular motion. As a sample of matter cools, the atoms and/or molecules will lose mobility. Loss of mobility and vibrational energy, which are forms of kinetic energy, will become apparent when thermal energy is removed from the sample.
What term is defined as a measure of the average kinetic energy of the particles in a sample of matter?
Temperature is defined as a measure of the average kinetic energy of the particles in a sample of matter. It indicates how hot or cold an object is.
If you were able to measure the motion of all particles of a sample and you used you would actually e measuringedthis data to find the average?
Using this data, you could calculate the average kinetic energy of the particles in the sample. Kinetic energy is directly related to motion and is determined by the mass and velocity of the particles. By finding the average kinetic energy, you can understand the overall thermal energy of the sample.
If you were able to measure the motion of all of the particles of a sample and you used this data to find he average you would actually be measuring?
You would be measuring the sample's temperature. Temperature is related to the average kinetic energy of the particles in a sample. By measuring the motion of all particles and calculating the average, you are essentially determining the average kinetic energy and thus the temperature of the sample.
What would happen to the average kinetic energy of the molecules of a gas sample if the temperature of the sample increased from 20C to 40C?
We will use that formula and see. Celsius converted to Kelvin.20o C = 293.15 Kelvin40o C = 313.15 KelvinKEavg = 3/2RTKE = 3/2(8.315 J/mol*K)(293.15 K)= 3656 Joules================The average kinetic energy increased about 8% in value.

What happened to the kinetic energy of the particles in a sample of gas as the temperature of the sample increase?
As the temperature of a gas sample increases, the kinetic energy of the gas particles also increases. This is because temperature is a measure of the average kinetic energy of the particles in the sample. Therefore, an increase in temperature corresponds to an increase in the average kinetic energy of the gas particles in the sample.
Which property is a measure of the average kinetic energy of the particles in a sample of matter?
Temperature is the correct answer because temperature measures average kinetic energy.
What is a measure of average kinetic energy of a group of molecules?
The temperature of a sample of nitrogen gas is a measure of the molecules' average # activation energy # potential energy # kinetic energy # ionization energy Answer 3 Reason Temperature measures average kinetic energy.

An increase in the average kinetic energy of a sample of copper atoms occurs with an increase in what?
An increase in the average kinetic energy of a sample of copper atoms occurs with an increase in temperature. Temperature is a measure of the average kinetic energy of the particles in a substance, so as temperature increases, the particles (such as copper atoms) gain more energy and move faster, which increases their kinetic energy.

When a sample of gas is heated at constant pressure the average kinetic energy of its molecules?
KEavg = 3/2RT Just need to know the temperature, T. ( in Kelvin ) R is a constant.
