When completely​ empty, a 1.5 gallon​ [gal] tank weighs 118 newtons​ [N] on the Earth. Now on​ Mars, the tank is filled with oxygen ​(O2​) with a molecular weight of 32 grams per mole​ [g/mol]. Inside the oxygen​ tank, the pressure is 5800 kilopascals​ [kPa], and the temperature is −196 ​(negative 196) degrees Celsius ​[°​C]. What is the total weight of the tank now that it is full of oxygen in Mars gravity in units of​ pound-force ​[lbf​]. The acceleration due to gravity on Mars is 3.71 meters per second squared ​[m/s2​].

C3-CRT35: PRESSURE-VOLUME GRAPH-PRESSURE, VOLUME, AND TEMPERATURE BAR CHARTS An ideal gas trapped in a cylinder expands while its pressure drops. The starting point for this process is labeled A and the endpoint is labeled B in the graph of pressure versus volume. 0 Explain your reasoning. Pressure 0 A Volume This initial pressure, volume, and temperature are shown in the histograms. Complete the histograms, showing the final pressure, volume, and absolute temperature.

The temperature on a warm summer day is 104 ° F. What is this temperature a. in degrees Celsius? b. on the absolute (Kelvin) scale

Part 1: Bullet A 52 g bullet is fired from a height of 458 m. The initial speed of the bullet is 140 m/s. The bullet eventually comes to rest in a bucket containing 2.9 kg of olive oil that is at ground level. As a result of bringing the bullet to a stop (any change in PE while in the olive oil is negligible), how much does the temperature of the olive oil increase (express the answer in K)? Also determine how fast the bullet is going at impact. Ignore air drag and assume that all of the thermal energy generated goes into heating the olive oil. Impact speed = AT= Part 2: Nail A 0.52 kg hammer strikes a 28 g copper nail into wood board. The nail is horizontally aligned and at the moment of impact with the nail, the hammer had a speed of 8.9 m/s. Assume both the hammer and the nail come to a stop and that all of the thermal energy generated goes into heating the nail. Determine how much the temperature of the nail will increase after one hit and how many hits it will take to increase its…
