in order for scientists to better investigate planets, they often use space probes. one such space probe, juno, arrived at jupiter's atmosphere in 2016. the probe was able to detect lightning on the planet's surface. from the information gathered from juno, scientists determined that, unlike on earth, most of the lightning on jupiter occurs at its poles. some scientists hypothesize that this is because there is more heat coming up at jupiter's poles due to hot convection currents below its surface. what does this information about juno demonstrate?
This information demonstrates that space probes can provide valuable data and insights about planets that cannot be gathered from Earth. It also shows that scientists can use this data to confirm or challenge existing hypotheses about planetary phenomena.

A student was studying chemical reactions. He followed these steps in an investigation:
Label one test tube X and another similar test tube Y.
Fill each test tube with 25 mL of the same acid solution.
Add 25 mL of the same salt solution to each test tube.
Carefully place test tube X in a beaker of water on a hot plate and increase the temperature.
Place test tube Y in a test tube holder on the table.
Record observations.
The student observed that a color change in test tube X occured faster than in test tube Y. Why did this happen?
A.
When the temperature was raised, the particles collided faster.
B.
Raising the temperature increased the air pressure around the test tube.
C.
Raising the temperature increased the number of particles in the test tube.
D.
When the temperature was raised, the particles became lighter.
A. When the temperature was raised, the particles collided faster.

The information about Juno and its detection of lightning on Jupiter's surface demonstrates the valuable role of space probes in scientific investigations of other planets. By sending space probes like Juno to explore other celestial bodies, scientists can gather data and directly observe phenomena that would otherwise be impossible or very challenging to study. In this case, Juno's arrival at Jupiter's atmosphere in 2016 allowed scientists to detect lightning on the planet, which provided new insights into the atmospheric conditions and weather patterns on Jupiter.
Additionally, the observations made by Juno helped scientists make a significant discovery about Jupiter's lightning patterns. By determining that most of the lightning on Jupiter occurs at its poles, unlike on Earth where it is more evenly distributed, scientists were able to form a hypothesis about the reasons behind this difference. The hypothesis suggests that the presence of hot convection currents below Jupiter's surface may lead to more heat rising to its poles, consequently resulting in increased lightning activity in those regions.
Therefore, the information gathered by Juno not only contributes to our understanding of the specific characteristics of Jupiter's environment but also provides valuable data for scientists to develop hypotheses and theories about the underlying processes responsible for the observed phenomena.
