Your answer must be supported by a mathematical calculation. b) Which molecule have the greater average kinetic energy (if either): O2 or CO2? Your answer must be supported by a mathematical calculation.

In what way do investigations build scientific knowledge? the results of investigations lead to questions that cannot be tested. they reflect the opinions and social values of scientists, ensuring valid information. the results of investigations lead to new questions, which lead to new investigations. they are not influenced by the research of earlier scientists, so they are able to address gaps in understanding. i
