Why does temperature decrease when gas expands?
The frequency of atomic collisions decrease as air expands, therefore the air gets cooler. Temperature is just the average heat of a substance. As the energy needed to increase it’s temperature must be supplied from somewhere, the gas takes the energy from the surrounding system giving the effect of cooling.
How does the temperature affect the average kinetic energy of gas molecule?
According to Kinetic Molecular Theory, an increase in temperature will increase the average kinetic energy of the molecules. As the particles move faster, they will likely hit the edge of the container more often. Increasing the kinetic energy of the particles will increase the pressure of the gas.
What happens to the average kinetic energy of the gas particles if the temperature decreases?
When temperature decreases, the average kinetic energy of the gas molecules decreases as well. This means that in order for the pressure to be constant, the volume needs to decrease, to compensate the lower average kinetic energy of the molecules.
How does the temperature affect the average kinetic energy of gas molecules as the temperature decreases the average kinetic energy of gas molecules?
The average kinetic energy of the particles in a gas is proportional to the temperature of the gas. Because the mass of these particles is constant, the particles must move faster as the gas becomes warmer. The volume of the gas therefore becomes larger as the temperature of the gas increases.
Does kinetic energy decrease and temp increases?
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. Therefore, the thermal energy of an object increases as its temperature increases.
How does average kinetic energy depends on temperature?
How is average kinetic energy related to temperature?
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.
