All ACT Question 2

Gasses that exist in the atmosphere remain in it for varying amounts of time. Two gases mentioned in each hypothesis, nitrous oxide and methane, have different ‘lifespans’ in the earth’s atmosphere. How do they relate?

Which hypotheses operate on the assumption that gases have the potential to trap heat in earth’s atmosphere?

Which statement, if true, would disprove hypothesis 3?

According to the author of hypothesis 2, would it be possible for earth’s temperature to increase if the amount of heat methane traps in the atmosphere increased?

Which hypothesis, if any, asserts that the effects of methane but not nitrous oxide will increase sea levels?

Which hypothesis, if any, asserts that the effect on temperature of heat trapping gases is negligible?

Suppose that after the experiment the chemist made a mistake and mixed up storage of the elements Oxygen and Argon. How would the chemist be able to identify which element is which if both are currently at a room temperature of 23 degrees Celsius?

If the Melting Point and Boiling Point characteristics of experiments 1 and 2 were to be generalized to all other elements, which of these statements would be false?

If each element were returned to its state at room temperature (23 degrees Celsius), how many elements would be liquid?

If each element were returned to its state at room temperature (23 degrees Celsius), how many elements would be solid?

Suppose that after the completion of Experiment 2, the chemist wanted to test the state of matter each element would be in at room temperature (23 degrees Celsius). How would the chemist most effectively do this?

If the chemist had continued heating the elements in Experiment 1 past their Melting Point until they boiled without stopping, would the results be the same as in Experiment 2?

Based on the results of Experiments 1 and 2, it is safe to conclude:

In general, is Testosterone concentration greater in the FR or MR condition?

In both the MR and FR conditions for Testosterone, how do concentrations at the Post 30 timestamp relate to concentrations at the Pre timestamp?

Suppose the researchers added another exercise to the end of the workout in the FR condition and measured Free Testosterone concentration at that point. If the current trend continued, what would be the most likely concentration observed at that timestamp?

At which timestamp is there the greatest difference in Testosterone concentration between the MR and FR conditions?

At the Pre timestamp, is there a higher concentration of Free Testosterone in the FR condition or Testosterone in the MR condition?

In both the MR and FR conditions, Testosterone concentration is implied to peak by a certain time stamp. What is that timestamp?

In both the MR and FR conditions, Free Testosterone concentration exhibits a trend during the duration of the workout. What is that trend?
