Read the descriptions of physical or chemical changes in the table below. Then decide whether the change will be spontaneous, if you can. Change A solid absorbs heat and turns to a gas. A solid precipitates from a solution, absorbing heat as it does so. A gas expands without absorbing or releasing heat. Is this change spontaneous? Yes. No. Can't decide with information given. Yes. No. Can't decide with information given. Yes. No. Can't decide with information given.
