Baking a cake is an example of:
-
A physical change
Partly right. Some of the changes involved in baking a cake are physical changes. -
A chemical change
Partly right. Some of the changes involved in baking a cake are chemical changes. -
Both
Yes! The process of baking a cake involves many changes. Some, such as water evaporating and sugar melting are physical changes. Others, such as baking powder reacting cause a change in the chemical formulas, indicating a chemical change. For more on this, read Changing How We Look at Changing -
Neither
No. There are many changes involved in baking a cake.

I poured some water on this rock. Later that day, the water was all gone. What happened to it?
-
It evaporated.
Yes. When liquid water turns into water vapor, the process is called evaporation. That is what happened to the water on the rock. -
It sublimated.
No. Sublimation is when a solid turns directly into a gas. Dry ice (frozen carbon dioxide) is an example of sublimation. The solid changes directly into carbon dioxide gas, without becoming a liquid. -
It condensed.
No. Condensation is when a gas turns into a liquid. The drops of water that form on the outside of a glass of ice is the result of condensation. -
It precipitated.
No. In weather, precipitation is when solid or liquid water falls from the clouds. Rain, snow, and sleet are examples of precipitation.

One test for identifying minerals involves rubbing the mineral on a rough tile, and looking at the color of the mark it leaves. This test is called:
-
Cleavage
No. Cleavage is when a mineral breaks along planes of weakness to form flat surfaces. -
Hardness
No. Hardness is the resistance of a mineral to being scratched by other substances. -
Fracture
No. Fracture is when a mineral breaks but does not show cleavage. -
Streak
Yes. The streak test examines the color of the mineral when it is powdered by rubbing it on a rough tile or streak plate. While the actual color of a mineral can vary, it will always produce the same color streak.

Incandescent light bulbs use electrical energy to produce light energy, but it is not a direct transformation. Instead, the electrical energy is changed to a different form of energy, and then to light.
Electricity → ? → Light
What form of energy does the "?" represent?
-
Sound
No. Electrical energy can be transformed into sound energy, but that would not cause the bulb to light. -
Thermal
Yes. As electrical energy flows through the filament, resistance changes the electrical energy into thermal energy. When the filament gets hot enough, some of the thermal energy is converted into light. -
Radiation
No. The electrical energy is not transformed into radiation. -
Friction
No. The electrical energy is not transformed into friction.

Rainbows are produced by:
-
Refraction
Partly correct. Light entering the raindrop is reflected off of the back surface. -
Reflection
Partly correct. As the light passes from air to water, and from water to air, the light is bent or refracted. Different colors are refracted different amounts, separating the colors. -
Both reflection and refraction
Correct! When you see a rainbow, the sun will always be behind you. (There are other, similar looking phenomena which you see when facing the sun, but they are not rainbows.) The sunlight enters each raindrop, is refracted (bent). Different colors are refracted different amounts. When the light hits the far side of the raindrop, part of it goes on through, and part of it is reflected back towards the sun (and towards you.) As it passes leaves the drop, the difference in density from water to air refracts (bends) the light even more, separating the colors into bands for the rainbow. -
Neither reflection no refraction
No. One or both take part in producing the rainbow.
