1. suppose that you have two boxes one is 20 cm X 20 X 20 cm. The other is 20cm X 20 cm X 40 cm. a.) how does the pressure of the air on the outside of the two boxes compare?

b.) How does the magnitude of the total force of the air on two boxes compare?

2. In a certain internal combustion engine 0.0021 m^3 of the air at atmospheric pressure and 303 K is rapidly compressed to a pressure of 20.1 x 10^5 Pa and volume of 0.0003 m^3 what is the final temperature of the compressed gas?

3.) A tank truck takes a load of 45,725 L of gasoline in houstin where temp is 28.0 C the truck delivers its load in minneapolis where the temp is -12.0C

a.) how many liters of gas does the truck deliver

b.) what happened to the gas?

please help me answer one of these or all if you can its due tmro thank you so much

True or false: the revolution of the earth creates day and night as it rotates around the sun

Some material consisting of a collection of microscopic objects is kept at a high temperature. a photon detector capable of detecting photon energies from infrared through ultraviolet observes photons emitted with energies of 0.3 ev, 0.5 ev, 0.8 ev, 2.0ev, 2.5ev, and 2.8ev. these are the only photon energies observed. (a) draw and label a possible energy-level diagram for one of the microscopic objects, which has four bound states. on the diagram, indicate the transitions corresponding to the emitted photons. explain briefly. (b) would a spring–mass model be a good model for these microscopic objects? why or why not? (c) the material is now cooled down to a very low temperature, and the photon detector stops detecting photon emissions. next, a beam of light with a continuous range of energies from infrared through ultraviolet shines on the material, and the photon detector observes the beam of light after it passes through the material. what photon energies in this beam of light are observed to be significantly reduced in intensity (“dark absorption lines”)? explain briefly.
