AP Physics 2 Midterm Review

Front

What is the work done in a complete cycle on a PV graph for an ideal gas?

Back

The work done in a complete cycle (A→B→C→A) on a PV graph for an ideal gas is 0 J.

Front

How do you find the temperature at a specific point on a PV graph for an ideal gas?

Back

The temperature at a point on a PV graph can be found using the ideal gas law, PV=nRT.

Front

What happens to a proton moving in the direction of electric field lines?

Back

A proton moving in the direction of electric field lines is moving from high potential to low potential and losing electric potential energy.

Front

What occurs when uncharged bits of paper are brought near a charged comb?

Back

There is attraction because the paper is a dielectric.

Front

What is the relationship between temperature and average translational kinetic energy in an ideal gas?

Back

The temperature of the gas is proportional to the average translational kinetic energy of the molecules.

Front

Do all molecules in an ideal gas have the same speed?

Back

No, not all of the molecules have the same speed; they have a distribution of speeds.

Front

What is the significance of elastic collisions in an ideal gas?

Back

Molecules make elastic collisions with each other and with the walls of the container, conserving kinetic energy.

Front

How does temperature affect the number of collisions per unit time in an ideal gas?

Back

The average number of collisions per unit time that the molecules make with the walls of the container depends on the temperature of the gas.

Front

What is the ideal gas law?

Back

The ideal gas law is PV=nRT, where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature.

Front

What is a PV graph?

Back

A PV graph is a plot of pressure (P) versus volume (V) for a gas, showing the relationship between these two variables.
