Heat flows into an ideal gas at a constant volume. The pressure increases from 1.5 atm to 5.5 atm. Next the gas is compressed at constant pressure from 5.0 L to 2.5 L and goes back to its original temperature.
What is the total work done on the gas in the process?
What is the total change in internal energy?
What is the total heat flow of the process?

If you have 0.326 m^3 of water at 25 degrees celsius and add 0.127 m^3 of water at 95 degrees celsius; what is the final temperature of the mixture
A 2kg ball moving east with a speed of 3m/s collides with another 3kg ball moving west with a speed of 4m/s . After the collision the two balls stick together
An alpha particle (the nucleus of a helium atom formed by 2 protons and 2 neutrons with charge q = +2(1.6 x 10-19 C), Calculate the acceleration of the alpha particle
The power is off for 34.0 s and throughout this time the flywheel slows as a result of friction in its axle bearings. Throughout the time the power is off, the flywheel makes 180 complete revolutions.
The ball has the speed of 12.1 m/s and is moving in a direction of 33.4 degrees east of north, relative to the ground.
