Answer:
Mass is how much matter an object has. Weight is how much gravity an object is being acted upon.
Explanation:
The mass of an object will stay the same no matter where you place it. But if you were to place the object, in the moon for example, then the weight of the object would be less since there is less gravity on the moon.
It became so cold during the course of the night, making it hard enough just to skate on. or the lake had frozen completely due to the extreme weather outside.
one of the key circumstances for the existence of matter. Traditionally, matter may exist in three different states: solid, liquid, or gas. For instance, the same chemical exists in the three different states of ice, liquid water, plus steam.
Plasma, a state of matter that is electrically neutral, is frequently regarded as the final state of matter. The lake's temperature rose because it became so cold during the course of the night, making it hard enough just to skate on. or the lake had frozen completely due to the extreme weather outside.
Therefore, the lake had frozen completely due to the extreme weather outside.

Answer:
The lake went from a liquid to a solid
Explanation:
Since it was so cold overnight, the temperature of the lake increased to the fact that it turned hard enough to skate on. or The temperature outside was so cold it froze the lake solid
1: updating the atomic weight
2: adding newly discovered elements
However, I cannot come up with a last way the modern periodic table differs from Mendeleev's. Please help (:
The modern periodic table differs from Mendeleev’s original version in three main ways: it includes updated atomic weights, has been expanded to include newly discovered elements, and arranges elements by atomic number rather than atomic weight.
The modern periodic table of elements indeed differs in several key ways from the original 1869 version developed by Dmitri Mendeleev. Firstly, as you've noted, it has been updated to include the correct atomic weights of elements. Secondly, it has been expanded to include all of the newly discovered elements that weren't known in Mendeleev's time. And thirdly, elements on the modern periodic table are now arranged according to their atomic number (the number of protons in an atom's nucleus), rather than their atomic weight as was initially the case with Mendeleev's version. This change reflects a deeper understanding of atomic structure that has developed since the 19th century.

Answer: melt
Explanation:
A. research question
B. scientific theory
C. scientific law
D.hypothesis
I think its B or D.
Answer:
B. scientific theory
Explanation:
The scientific theory explains the phenomenon observed in the natural world. It is based upon the scientific method. To arrive at the scientific theory a hypothesis is formed, experiments are designed and conducted, resulted evaluated, analyzed and conclusions are reached. scientific theory are based upon experiments that are tested under controlled conditions.
