Two large containers A and B of the same size are filled with different fluids. The fluids in containers A and B are maintained at 0° C and 100° C, respectively. A small metal bar, whose initial temperature is 100° C, is lowered into container A. After 1 minute the temperature of the bar is 90° C. After 2 minutes (since being lowered into container A) the bar is removed and instantly transferred into the other container. After 1 minute in container B the temperature of the bar rises 10°. How long, measured from the start of the entire process, will it take the bar to reach 99.5° C? (Round your answer to two decimal places. Assume the final temperature being asked for is reached while the bar is container B.)

1)Two rigid tanks of equal size and shape are filled with different gases. The tank on the left contains oxygen, and the tank on the right contains hydrogen. Assume both gases are ideal. The molar masses of oxygen and hydrogen are 32 and 2, respectively. Both containers are at the same temperature. A pressure gauge is pin oxygen hydrogen connected to each tank. Both gauges show a reading of 230 kPa. Is the number of oxygen molecules in the left...
I have filled in two glass gas bulbs with the same pressure of two different gasses: hydrogen gas (H2) and propane gas (CH,CH,CH3). The gas bulbs have the same volume and are also kept at the same temperature. Which of the two bulbs contains more molecules of gas? Select one: a. The bulb filled with propane contains more molecules, because propane has a greater molar mass than hydrogen b. The bulb filled with propane contains more molecules, because one propane...
