The best and most correct answer among the choices provided by your question is the fourth choice which is "Heat moves through conduction, convection, and radiation."

Heat transfer is the exchange of thermal energy between physical systems. The rate of heat transfer is dependent on the temperatures of the systems and the properties of the intervening medium through which theheat is transferred. The three fundamental modes of heat transfer are conduction, convection and radiation.

Answer from: 200002977

Heat moves through conduction, convection, and radiation.

Explanation:

Hello,

In this case, heat transport is possible via conduction, convection and radiation which are defined as follows:

- Conduction: it happens when two or more objects have different temperatures and they are touching each other, thus, the energy is transferred from the hot to the cold object. For example, we can warm our hands by touching hot receptacles or objects.

- Convection: it occurs when a flowing fluid gets in contact with a surface at a different temperature, causing the heat transfer from the hot to cold region. For instance, when the air is freezing, it cools us down as we "provide" heat to it.

- Radiation: it occurs when a heat body transfers energy to its surroundings by the creation of heatwaves which are released due to the temperature difference with its surroundings.

Best regards.

Answer from: Quest

There is no reason to think the results are biased or not conducted properly but you should not assume the results are correct just because they were done in a laboratory so the answer would be c. it is likely to be reliable because the results support the conclusion presented.

These questions are based on the attached photo. the experiment is about burning magnesium metal with oxygen. 1. write the balanced chemical equation for the reaction you are performing. 2. calculate the mass of magnesium metal used in each trial. o trial 1: o trial 2: 3. calculate the actual yield of magnesium oxide for each trial. o trial 1: o trial 2: 4. magnesium is the limiting reactant in this experiment. calculate the theoretical yield of mgo for each trial. o trial 1: o trial 2: 5. determine the percent yield of mgo for your experiment for each trial. o trial 1: o trial 2: 6. determine the average percent yield of mgo for the two trials. your company currently uses a process with a similar cost of materials that has an average percent yield of 91 percent. if the average percent yield of this process is higher than that, this could save the company money. what is your recommendation to the company? support your recommendation using your data, calculations, and understanding of stoichiometry gathered from this lab.
