A) condensation
Condensation is the transformation of a gaseous state into a liquid one, and it is the inverse of vaporization. The term is most commonly used to describe the water cycle.
Deposition is a phase transition in which a gas becomes a solid without first passing through the liquid phase.
Sublimation is the process of converting a solid to a gaseous state without it being liquid.
Vaporization of an element or compound is a phase transition from the liquid phase to vapor.
Therefore, During a hot shower, water vapor fogs up the cooler mirror when it turns to water. This is an example of A) condensation

In the periodic table, the most reactive metals are found a. in Group 1, the first column on the left. b. in Period 1, the first row across the top. c. in Groups 13 through 16 in the center. d. in Periods 6 and 7 at the bottom.
Answer:
Group 1
Explanation:
The alkali metals are the most reactive metals found on the periodic table
In a periodic table, the most reactive metals are found in Group 1, the first column on the left. (option a)
The most reactive metals are found in Group 1, which is the first column on the left side of the periodic table. Group 1 is also known as the alkali metals. These metals include elements like lithium (Li), sodium (Na), and potassium (K). Alkali metals are highly reactive because they have only one electron in their outermost energy level.
This means they are eager to lose that electron and achieve a stable electron configuration, which makes them more likely to engage in chemical reactions.
As we move down Group 1, the reactivity increases because the outermost electron is farther from the positively charged nucleus, making it easier to lose.
Hence the correct option is (a).

What is the relationship between an experiment and a hypothesis?
A. An experiment should be designed so that the hypothesis is
proven to be true.
B. A well-designed experiment is one that can test a number of
different hypotheses.
O C. A useful hypothesis is one that can guide the design of an
experiment.
O D. A hypothesis is an educated guess as to the outcome of an
experiment.
A useful hypothesis is one that can guide the design of an experiment. The correct option is C.
What are an experiment and hypothesis?It is possible to create fresh hypotheses and experiments that more closely match the results of the initial studies' observations. A hypothesis is formulated to explain an observation, and an experiment is created to test it. The experiment's findings might or might not support the hypothesis.
Negative results do not necessarily imply that the hypothesis is invalid. It implies that there must be another connection between the variables. To accomplish this, a new theory and experiment must be created in order to better account for the observations.
Therefore, a useful hypothesis is one that can guide the design of an experiment. The correct option is C.

The forced exerted on an object are shown. If the object moves right, which of the following is a possible value of F? Ignore my answer please help.
Answer:
5N
Explanation:
Because if it moves to the right, that means F is weak and 6N is STRONK
Our data for how much force is needed can be qualitative. This means we don’t have to know exact values for the force in Newtons. Let’s use a scale of 1-5 to rank how much force we apply each time.
6. How many different masses should we use?
How many trials should we do for each mass?
Answer:
For macroscopic objects, we use units such as grams and kilograms to state their masses, but. There will not be much error if you estimate the mass of an atom by simply. to what we did for our hypothetical example, but the percentages are different: Add two atomic masses of carbon and six atomic masses of hydrogen:
