A student wants to perform an experiment with an enclosed gas to investigate the relationships shown in the combined gas law. Which statement describes a condition that must be met?(1 point)

Question

Responses

Temperature must be measured in degrees Fahrenheit.
Temperature must be measured in degrees Fahrenheit.

Temperature must be measured in degrees Celsius.
Temperature must be measured in degrees Celsius.

The amount of gas must be held constant.
The amount of gas must be held constant.

Pressure must be held constant.

Answer 1

The correct statement that describes a condition that must be met for experimenting with the combined gas law is:

The amount of gas must be held constant.

The combined gas law relates pressure, volume, and temperature of a fixed amount of gas, allowing you to analyze the relationships between these variables. While temperature should be measured in Kelvin for gas law calculations, the key condition for the combined gas law to apply is that the amount of gas remains constant.
