Please submit the answer to this problem on a separate piece of paper, in submission box. 10.0 mol of argon (monoatomic) gas is introduced to an empty 50-cm container at 20°C. The gas then undergoes an isobaric heating to a temperature of 300°C. a) What is the pressure at which this process happens? b) What is the final volume of gas? c) Show this process on a PV diagram. Make sure you include units and properly label axes. d) What...
A copper block is removed from a 370 ∘C oven and dropped into 1.10 kg of water at 21.0 ∘C. The water quickly reaches 30.0 ∘C and then remains at that temperature. What is the mass of the copper block? The specific heats of copper and water are 385 J/(kg⋅K) and 4190 J/(kg⋅K) respectively.
Please submit the answer to this problem on a separate piece of paper, in submission box. A solid sphere, a solid disk, and a thin hoop are all released from rest at the top of the incline (ho = 20.0 cm). a) Without doing any calculations, decide which object would be spinning the fastest when it gets the bottom. Explain b) Again, without doing any calculations, decide which object would get to the bottom first. Hint: which one has greater...
