What happens to the volume of the gas being measured (o2 consumption or co2 production) when the temperature or pressure changes during the experiment? if pressure and temperature remain constant, will the volume of gas in the respirometers increase or decrease?

Volume of a gas is directly proportional to its temperature and inversely proportional to its volume.

Explanation:

As per the gas law

where

are pressure of gas

are volume of gas

are temperature of gas

This equation shows that the pressure is inversely proportional to the volume of gas and directly proportional to the temperature of a gas

Thus, if pressure remains constant, the volume of gas will also remain constant (if all other physical and chemical condition remains the same)

weathering - colorado river carves land in arizona to form the grand canyon. cracks form in a sandstone wall surrounding a house. a marble statue near the science museum is changing color due to rainfall

erosion - after a rainstorm, soil and rock piees litter the roadways. the sand dunes in the sahara desert are changing shape.

here's your answer.
