Two students were doing a lab. They mixed two chemicals together. The chemicals mixing caused a temperature change, a permanent color change, and evaporation of some liquid. What type of change took place here?
Physical Change, because there was a phase change from liquid to gas
Chemical Change, because there was a phase change from liquid to solid
Chemical Change, because there was a color change and temperature change
Physical Change, because it was just a change in appearance

When lemonade powder and water are mixed, the water changes color from clear to yellow and there is powder on the bottom of the glass. However, if the lemonade is left overnight, the water and powder begin to separate.
Which type of change takes place
Physical, because there is a phase change
Physical, because it is just a mixture
Chemical, because there is a color change
Chemical, because there is a percipitate
