g During a phase change, (large amounts/no/small amounts) of energy are being transferred into or out of the substance, even though the temperature of the substance is (decreasing/increasing/constant). [select the best answer in the parentheses to fill in the blanks] The beaker in experiment 2 is considered to be a (an) system. Energy could be entering the system from . Energy could be leaving the system through .

The diagrams to the right show the distribution and arrangement of gas particles in two different containers. according to kinetic-molecular theory, which of the following statements is true? check all that apply. if the temperatures of both containers are equal, container a has greater pressure than container b. if the volume of container a decreased, its pressure would decrease. if the pressure in both containers is equal, container a has a lower temperature than container b.
