A graph enables you to easily denote the relationship between variables as positive or negative.
<h3>What is a graph?</h3>
This question is incomplete but I will try to help you as much as I can. A graph is one of the numerous was of data representation in science. A graph has two axes; the vertical ( Y - axis) and the horizontal (X - axis).
A graph enables you to easily denote the relationship between variables as positive or negative. A graph is sometimes called a scatter plot.

Answer: Reaction (1) , (3) and (4) are accompanied by an increase in entropy.
Explanation:
Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.
(1) 
3 moles of reactant are changing to 1 mole of product , thus the randomness is increasing. Thus the entropy also increases.
2) 
1 mole of Liquid reactant is changing to 1 mole of solid product , thus the randomness is decreasing. Thus the entropy also decreases.
3) 
1 mole of Liquid reactant is changing to 1 mole of gaseous product , thus the randomness is increasing. Thus the entropy also increases.
4) 
1 mole of Liquid reactant is changing to half mole of gaseous product and 1 mole of liquid product, thus the randomness is increasing. Thus the entropy also increases.
1.Some earthquakes are associated with volcanoes. A lot of earthquakes are alongside the rims of tectonic plates. This is in which some volcanoes are too.
2. Earth changes in its personal ways. Some changes are because of gradual processes, consisting of erosion and weathering, and a few changes are because of fast processes, consisting of landslides, volcanic eruptions, Tsunamis and earthquakes. Waves, wind, water, and ice form and reshape the Earth's land surface through eroding rock in a few regions and depositing them in different regions, now and again in seasonal layers. Tectonic plates drift, the crust quakes, and volcanoes erupt. All of these effective forces form our air, land, water, and climate and are constantly reworking our planet.
Coal releases carbon dioxide when burned. The reaction looks like this:
C(s)+O₂(g)→CO₂(g)
I hope this helps. Let me know in the comments if anything is unclear.
