Experiments cannot validate hypotheses, only falsify them. The statement above can be restated in which of the following ways?
Until disproved, an explanation for an observation is valid.
Certain concepts cannot be subjected to direct experimentation.
A hypothesis that has not been falsified remains provisional.
Proving a hypothesis exempts it from further testing.
The Correct Answer is C
The statement "Experiments cannot validate hypotheses, only falsify them" can be restated as "A hypothesis that has not been falsified remains provisional." This means that a hypothesis is considered valid until it is disproved by experimental evidence. However, even if a hypothesis has not been falsified, it is still considered provisional and subject to further testing and scrutiny.
A. "Until disproved, an explanation for an observation is valid" is similar to the correct answer but does not capture the provisional nature of a hypothesis.
B. "Certain concepts cannot be subjected to direct experimentation" is not a restatement of the original statement.
D. "Proving a hypothesis exempts it from further testing" is incorrect because no hypothesis can be definitively proven and all hypotheses are subject to further testing and scrutiny.

Correct Answer is D
Explanation
The triple point of a substance is the temperature and pressure at which the substance exists simultaneously in solid, liquid, and gas phases ¹. In thermodynamics, the triple point of a substance is the temperature and pressure at which the three phases (gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium ¹.
The other options are not correct because they do not accurately describe the triple point of a substance. Sol, gel, and plasma are not phases that coexist at the triple
Correct Answer is C
Explanation
The data in the table does not support any of the conclusions a, b or d. The only conclusion that can be drawn from the data is c. The time of fall is independent of the mass of the object. This is because objects 1 and 2 have the same mass but different times of fall, while objects 3 and 4 have different masses but also different times of fall.
A. Objects A and B are not mentioned in the table, so this conclusion cannot be drawn from the data.
B. The data does not support the conclusion that the greater the mass of an object, the faster it will fall. In fact, object 3 has a greater mass than object 2 but falls in less time.
C. Air resistance is not mentioned in the table, so this conclusion cannot be drawn from the data.
