You curl your hair with a curling iron. You curl your hair by getting a “permanent wave” at the hair salon. Ice on your sidewalk melts when you put salt on it. A glass of water evaporates overnight when it is left on the bedside table. Your steak chars if the skillet is too hot. Alcohol feels cool when it is spilled on the skin. Alcohol ignites when a flame is brought near it. Baking powder causes biscuits to rise.arrow_forwardDistilling a red liquid physically separates it into a red solid and a clear, colorless liquid.

- Which of the following statements is a scientific theory? (a) The energy in an atomic nucleus is found by E = mc². (b) There is the same number of molecules in equal -volumes of gases. (c) If the temperature of a gas doubles, the pressure doubles. (d) The region surrounding the nucleus has negative charges.arrow_forwardContainer A and Container B were filled completely with chicken powder. The total mass of 1/3 of the chicken powder in Container B and 1/11 of the chicken powder in Container A was 570 g. If 5/11 of the chicken powder in Container A was poured out, the total mass of the chicken powder in both containers became 2.28 kg. How much chicken powder was in (a) Container A in grams? (b) Container B in grams?arrow_forward5 Water is evaporated from the magnesium chloride solution. The resulting solid is melted at 700°C and decomposed by passing electric current through it.
