A rigid cylinder with a movable piston contains a sample of gas. At 300. k, this sample has a pressure of 240. Kilopascals and a volume of 70.0 milimeters. What is the volume of this sample when the temperature is changed to 150. K and the pressure is changed to 160. kilopascals? Based on the reading above, what is the initial volume?
1) 70 mL
2) 150 K
3) 160 kPa
4) 240 kPa

Two metal blocks that have slightly different temperatures are placed next to one another. after five minutes, they both have lower but equal temperatures. according to the law of conservation of energy, what  most likelyhappened? energy was created inside the blocks.energy was destroyed inside the blocks.energy was absorbed into the blocks from outside the system.energy was transferred from the warmer block to the cooler block.
