The pressure of a gas will increase when: OA the volume increases o the temperature decreases oc. the volume decreases OD. the size of the container increases O E none of these are correct QUESTION 17 A liquid A has no definite shape and no definite volume os has a definite volume but no definite shape oc has a definite shape but no definite volume OD none of these are correct O E has both a definite shape and a...
The entropy of a substance increases as we change it from solid to liquid to gas, as we increase the motion and configurations possible (and go from a highly ordered structure to one lacking any structure). With this comes the expectation that dissolving a solid (changing state from solid to aqueous) will increase the entropy of the system. Using Appendix II from your textbook, calculate the entropy for the dissolution of MgCl2, make sure to include the chemical equation you...

B) The temperature a The temperature and pressure determine the physical state in which a sample of matter will exist C) The solid state of matter is more organized than the liquid state of matter. D) Gases will assume the volume and shape of their containers. 41) How many moles of gas are present in...
