Answer:
Fluids (air/water) either as water vapour or oxygen and carbon dioxide.
Explanation:
Heat transfer occurs through conduction, convection or radiation.
Many aties, this involves fluids whose molecules have been activated by heated by heat, moving from hotter to cooler regions, allowing for heating or cooling of the rooms.
Building materials have varying conductivity.
B.They identify what phase the substances are in.
Answer:
Yes.
Explanation:
Yes, the change in cuvette lead to a determinate error in the analysis if the different cuvette is used for the analysis because the amount of liquid sample that is used has different volume. If both cuvette are of the same type and has no difference in their structure and size then there is error occurs in the analysis but if both cuvette are different from one another then the error will occur in the analysis. because the amount of liquid that is used has different volume.
I am going to assume that the reaction occurs in water since that is the easiest procedure (let me know if I am not supposed to make this assumption).
1) get 2 beakers, the chemicals for the reaction, DI water, and the catalyst.
2) equal volumes and amounts of the water was placed into the 2 beakers.
3) some of the catalyst was added to beaker the second beaker.
3) equal amounts of the chemicals for the reaction was placed into the 2 beakers.
4) the two reactions were compared to see how the un-catalyzed reaction in beaker 1 was effected by the introduction of a catalyst in beaker 2.
I hope this helps. Let me know in the comments if anything was unclear.
Answer: Changing the amount of solute and volume of solvent we can change physical properties of the given salt water solution.
Explanation:
Physical properties are defined as the properties which does not cause any change in chemical composition of a substance. For example, density, mass, volume, etc are all physical properties.
When we take a salt water solution then on adding more amount of salt into the water there will occur change in density of the solution as density is mass present per liter of solution.
Also, if we add more amount of solvent then there will occur change in volume of the solution.
Hence, in both the cases physical properties of the solution are changing and no change in its chemical composition is taking place.
