Answer:
In a Lewis symbol, the symbol for the element is used to represent the atom and its core electrons. Dots placed around the atom are used to indicate the valence electrons. ... In 1916, Gilbert Newton Lewis, an American chemist, suggested that molecules were formed when atoms shared pairs of outer electrons.
Explanation:
Answer:
C.
Explanation:
Higher temperatures leads to higher growth rates this is because, as the temperature increases, the plants have more needs to respire leading to more cellular activities and release of more carbonioxide. The increase in atmospheric carbondioxide and cellular activities leads to increase in plant growth. However, it should be noted that the increase in temperature shouldn't go beyond a certain level as it can also cause adverse effects of crops.
True is the correct because helio means sun in greek and the sun is in the center of our universe
Answer:
Hypothesis
Explanation:
The following steps are applicable when we wish to prove a specific fact:
- a hypothesis is made; this is a statement that we provide after some observations and we wish to either prove or deny it;
- multiple experiments are carried out in order to gather significantly substantial amount of data that can be then further analyzed and any tendencies can be noticed;
- based on the data gathered, conclusions are made: we either prove or deny the hypothesis. If hypothesis is proved, it may become a theory over long time.
In the context of this problem, we're at the first step where we make a hypothesis.
Answer:
Explanation:
Air outside the cup affect the kinetic energy of the particles in the wall and the cold water by transferring its heat to the cup and cold water.
Explanation:
The air outside the cup has a high temperature as compared to that of the cold water with in the cup.
As this hot and moist air it comes in contact of cup, it transfers its heat energy and become cool itself thereby leaving water droplet on the outer side of the cup.
Due to heat imparted to the cup, the atoms with in the cup and cold water starts vibrating and hence there kinetic energy increase.
