Me ill give you a lot of points the volume of water in a graduated cylinder is 8.0 cm^3. the volume changes to 10.5 cm^3. when a 6.50 g sample of a substance is lowered into the cylinder. what is the density of the substance?

If i initially have a gas at a pressure of 12 atm, a volume of 23 liters, and a temperature of 200 k, and then i raise the pressure to 14 atm and increase the temperature to 300 k, what is the new volume of the gas?

Which of the following is a chemical property of water at 4 c

•what conclusions can you make about the relationship between the volume of a gas and its temperature? • what conclusions can you make about the relationship between the volume of a gas and its pressure? • what possible variables have you not accounted for? as you did the procedures, is it possible that the atmospheric pressure may have changed? if it did change over the course of your experiment, then how would your results have been affected?
