Answer:
a) ∆T=T1-T2
b) At the particle level the temperature changes are the result of the added energy causing the particles of water to move more vigorously. Either the particles of solid vibrate more vigorously about their fixed positions or the particles of liquid and gas move about their container more rapidly.
c) The state in which two substances in physical contact do not share any heat energy. The temperature of two substances in thermal equilibrium is said to be the same. Also see thermodynamics.

Answer:
Option B:Publishing scientific journals
Explanation:
We are told that Lindsey is trying to gain credibility for her studies.
Since she completed her experiment and discussed her finding with colleagues, the most logical next step would be to publish scientific journals. This is because the other options given are not steps that should be taken because she has completed the research and therefore has no need to speak at a conference next nor even create new charts which they must have done during the research. No need for her to make sure the topic is popular.
Option B is correct
The correct option is A.
In scientific investigation, variable refers to those parameters that are manipulated or changed in an experiment. Variables are those factors or conditions that can exist in different amounts in a scientific investigation. There are three major types of experimental variables, these are, independent, dependent and controlled variables. All the variables that are used in an experiment are usually connected to one another, scientific investigators typically look for the relationships among the variables in order to depict how they associate with one another.
