The data not given here is the specific heat capacity of pyrex glass equal to 0.75(J/g °C). In this case, heat is equal to mass x specific heat capacity x temperature rise. Temperature difference is then equal to 1910 J / 0.75 J/g °C / 23 g equal to 110. 75 <span>°C </span>
Answer:
Explanation:
In an experimental research, the control group is the group that serves as the neutral group that is not given any form of treatment and serves as the group in which the experimental groups are firstly compared to. Thus, <u>the control group in the question described is the Third group</u>.
While experimental groups are the groups that receive treatments required to make an inference from the experiment. From this description, <u>it can be deduced that the First and the Second group are the experimental groups.</u>
<span>The correct answer is B. Inverted image. This is because of all the lenses and light refractions and what not.
