Question

Which defines the average inetic energy of a system's particles?

O density
O pressure
O temperature
O volume

Answer 1

Answer:

Temperature

Step-by-step explanation:

Because Temperature is a measure of the average kinetic energy of all the molecules in a gas. As the temperature and, therefore, kinetic energy, of a gas changes, the RMS speed of the gas molecules also changes. The RMS speed of the molecules is the square root of the average of each individual velocity squared.
