What happens to the average kinetic energy at a constant temperature? * 1.it increases
2.it decreases
3.it stays the same
4.it disappears

The answer is A, it increases.

As the temperature increases, the average kinetic energy increases as does the velocity of the gas particles hitting the walls of the container. The force exerted by the particles per unit of area on the container is the pressure, so as the temperature increases the pressure must also increase.

Because a model would make the investigation easier to understand

Adozen is 12, and your needing to calculate the weight of one medium egg, so i would do 21/12=1.75 per egg, and check your answer by doing 1.75 * 12= 21 : ) : ): ): ): ) i hoped i
