Question

this state of matter has molecules that are close together, they vibrate in place, and they are not easily compressible
solid
liquid
gas
a researcher wants to know how changing the temperature affects the pressure of a container.
to do so, they create an experiment with 4 separate containers. each container is non - flexible, contains the same amount and type of gas. the first container is cold, the next is room temperature, the second is warm, and the last is hot. the researcher then measures the pressure of each container and records their results, finding that higher temperatures result in higher pressure
what is the dependent variable?
the temperature
the pressure

Explanation:

1. Solids have molecules that are closely - packed, vibrate in place, and are not easily compressible. Liquids have more freedom of movement for molecules and gases have widely spaced molecules that are highly compressible.
2. In an experiment, the dependent variable is the variable that is being measured and is affected by the independent variable. Here, the researcher is changing the temperature (independent variable) and measuring the pressure (dependent variable).

Answer:

1. A. Solid
2. B. The pressure
