Physics Homework

Full work and explanations, in complete sentences, required for all items. A solid sample of a substance has a mass of 180 g and a volume of 60 cm'. The sample is melted and the resulting liquid has a density of 2.4 g/cm3. 1) Does the number of tiny particles of the substance in the sample change when it melts? How do you know? 2) What is the mass of the liquid? How do you know? 3) What is the volume of the liquid? How do you know? 4) If we took the number of tiny particles in the solid sample times the volume of each would the result be greater than, equal to or less than 60 cm? Why? 5) Does the volume value just calculated change when the sample melts
