Temperature is a measure of kinetic energy. Because liquid nitrogen is very cold, a system's kinetic energy will be collisionally transferred to the added liquid nitrogen.
Thus, in general, adding liquid nitrogen will decrease a system's kinetic energy.
(There are some exceptions where the system has less kinetic energy than the liquid nitrogen, such as liquid helium.)
What else can I help you with?
The kinetic molecular theory assumes that the kinetic energy of gas molecules is proportional to what?
temperature in kelvin
Why nitrogen diffuses faster in high temperature?
Higher temperatures mean more heat energy which translates into more kinetic energy of the molecules of nitrogen gas. This greater kinetic energy allows the molecules to diffuse faster than at a lower temperature and lower kinetic energy.
Is the average kinetic energy per molecule the same for oxygen and nitrogen molecules in air at a given temperature?
Yes, at a given temperature, the average kinetic energy per molecule is the same for oxygen and nitrogen molecules in air. This is because the kinetic energy of a gas molecule is determined by its temperature, and not its composition.
Why is the average speed of helium particles in the room more than nitrogen molecules?
The average speed of helium particles in a room is greater than that of nitrogen molecules primarily due to their lighter molecular mass. According to the kinetic molecular theory, at a given temperature, lighter gases move faster than heavier gases because they have higher average kinetic energy. Helium, with a molecular weight of about 4 g/mol, is significantly lighter than nitrogen, which has a molecular weight of about 28 g/mol. As a result, helium particles will have a higher average speed compared to nitrogen molecules under the same conditions.
Temperature is relative to the energy of the molecules?
Increasing temperature will increase molecular speed.An object with less massive molecules will have higher molecular speed at the same temperature.When kinetic temperature applies, two objects with the same average translational kinetic energy will have the same temperature. An important idea related to temperature is the fact that a collision between a molecule with high kinetic energy and one with low kinetic energy will transfer energy to the molecule of lower kinetic energy.
What effect does heat have on molecular energy?
Heat increases the kinetic energy of molecules, causing them to move faster and collide with each other more frequently. This leads to an increase in molecular motion and higher energy levels in the system.
Does the kinetic molecular theory apply to electrons?
because kinetic energy have electltrolises
What is the measure of average kinetic energy?
The average kinetic energy of atomic and molecular particles is measured as temperature.
The difference between total and average molecular kinetic energy of a gas contained in a box?
I just figured this out, so here it is:Average kinetic molecular energy is based on temp(in kelvin).Ek= (3/2)RT ; where R is a constant(.0821), and T is temp in kelvin.Total molecular kinetic energy is:uRMS=[(3RT)/M]^(1/2) R equals 8.314 J/mol; T=kelvin; M=kg/mol
Temperature is an indication of what?
Molecular motion / kinetic energy.
Does velocity of molecular movement reflect kinetic energy?
no
Casey remembers that molecular motion increases as temperature increases. Identify what effect increased molecular motion.?
Increased molecular motion leads to higher kinetic energy among the molecules in a substance. This causes the molecules to move more rapidly and collide with each other more frequently. Consequently, temperature and molecular motion are directly related due to the kinetic energy of the molecules.
Explain the difference between total and average molecular kinetic energy of gas contained in a box?
Average Kinetic Energy is determined by the temperate of the gas. The higher the temperature, the higher the average kinetic energy of the gas molecules.Total Kinetic Energy is the average kinetic energy multiplied by the mass - the number of gas molecules in the box.- DENNIS LAM
In a refrigerator what kind's of energy is being used and in what order?
Kinetic. It's all kinetic (thermal heat energy is actually a form of kinetic energy applied at the molecular level.)
The kinetic molecular theory assumes that the kinetic energy of gas molecules is proportional to what?
temperature in kelvin
Is heat a form of kinetic energy?
Yes, heat is a form of kinetic energy because it is the energy associated with the movement of particles at the atomic or molecular level.
Why nitrogen diffuses faster in high temperature?
Higher temperatures mean more heat energy which translates into more kinetic energy of the molecules of nitrogen gas. This greater kinetic energy allows the molecules to diffuse faster than at a lower temperature and lower kinetic energy.
