Ben and sam were conducting experiments on physical and chemical changes in science class. first they added some salt to water and stirred it up until the salt dissolved. "that's a physical change" ben said. "and that's a solution which is a mixture", added sam. next they added an anti-acid tablet to some water. the water began to fizz and bubble. the beaker got cooler. "that's a physical change too," ben noted. "no, it's not," responded sam. who is correct and where should the contents of the beaker be placed in the venn diagram?
