Amixture is what you get when you combine two substances in such a way that no chemical reaction occurs between the components. a solution is a mixture that looks exactly the same everywhere. which of these mixtures is not a solution?

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
