Scientists are able to detect an El Niño<span> event and its effects on the climate through a variety of technological and natural sciences. One of these natural sciences is dendrochronology, or the study of tree rings. Dendrochronologists study the rings of a tree in order to understand climatic conditions during specific time periods. Thin rings often indicate drier seasons while fatter rings indicate rainy seasons. Depending on where the tree is, scientists can see past El </span>Niño<span> events in trees that exhibit signs of much rainier or drier seasons that normal.</span>
Answer:
The correct answer is option B. From 200K to 400K
Explanation:
Hello!
Let's solve this!
The ideal gas equation is the following PV = nRT
Where the variables are:
P: pressure
T: temperature
V: volume
R: universal constant of ideal gases
n: number of moles
We see in the equation the proportional relationship of volume with temperature.
We deduce that if the volume increases twice, then the temperature increases twice.
The temperature has to be in Kelvin, that's why we chose that answer.
Of the options, the correct answer is option B. From 200K to 400K

Answer:
so first what you would do is the first questions asking what is the average mass of the fruits! so in my head im looking at the graph and go i would add up all the fruits MASS make sure to add the mass only and get the total of the mass that all the fruits have. the seconed question is asking what is the average cost of the first purchase? look at the graph it says the first fruit cost 1.37 dollars. the third and last question is calculate the average cost per mass of the fruit purchassed. so this is a tricky one but ill help you what i think would take the cost of the fruit and divide it by the mass of each fruit! i hope tis helps you can do this! i can also say that question two is trying to make you think over it so dont its litteraly stated to you on the graph lol
