Question

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 are the control variables? the temperature the pressure the container and amount of gas

Explanation:

Control variables are kept constant in an experiment to isolate the effect of the independent variable (temperature here) on the dependent variable (pressure). The container's non - flexibility, same amount and type of gas are held constant, making them control variables. Temperature is the independent variable and pressure is the dependent variable.

Answer:

The container and amount of gas
