Question

this state of matter has an indefinite shape and a definite volume * 1 point
solid
liquid
gas
the classes you take in high school are examples of * 1 point
pure chemistry
applied chemistry
a scientific theory is * 1 point
a checklist of steps for experimentation
a summary or equation that has been repeated endlessly with experimentation
a long explanation of how things work that has been tested again and again

Explanation:

1. Liquids take the shape of their container (indefinite shape) but have a fixed amount of matter (definite volume). Solids have a definite shape and volume, and gases have an indefinite shape and volume.
2. High - school chemistry classes are general education courses and not focused on either pure or applied chemistry in a specialized way. But they are more related to basic knowledge rather than applied research - based applied chemistry.
3. A scientific theory is a well - tested explanation of how things work, not a checklist of experimental steps or just a summary/equation.

Answer:

1. B. Liquid
2. Neither (but if forced to choose, more like basic knowledge rather than applied chemistry)
3. C. A long explanation of how things work that has been tested again and again
