- Q3A sample of gas has a volume of 2.80 L at an unknown temperature. When the sample is submerged in ice water at t = 0 degrees Celsius, its volume decreases to 2.57 L What was its initial temperature (in Kelvins and in Celsius)? Assume a constant pressure. (to distinguish between the two temperature scales, use t for temperature in degrees Celsius and T for temperature in Kelvins)297 K and 24 degrees Celsius247 K and 29 degrees Celsius0.0264 K and - 273 degrees Celsius38.0 K and -235 degrees Celsius300s

- Q6Kinetic molecular theory is consistent with which properties of gases:They are compressible, assume shape a volume of their container, have low densities compared to solids and liquidshave energy proportional to volume, take up a lot of space, move at randomgas particles move in a straight line, have higher density compared to liquids, assume volume of their containergas particles move at random, gas particles attract each other, are proportional to temperature300s
