Answer: Radioisotopes are used by manufacturers as tracers to monitor fluid flow and filtration, detect leaks, and gauge engine wear and corrosion of process equipment. Small concentrations of short-lived isotopes can be detected whilst no residues remain in the environment.
Explanation: Uranium-235 is used for nuclear fission and as a fuel in nuclear reactors.
An isotope of cobalt is used in the treatment of cancer.
An isotope of iodine is used in the treatment of goiter.
Answer:
A parasitic relationship is one in which one organism, the parasite, lives off of another organism, the host, harming it and possibly causing death. The parasite lives on or in the body of the host. A few examples of parasites are tapeworms, fleas, and barnacles.
For this case, the first thing you should do is observe the level of the liquid in the graduated cylinder, where it is located.
This will result in its volume.
We have then that the volume is given by:
Answer:
the volume of liquid in the graduated cylinder is:
The heat will flow from Cu to Fe because Cu has higher temperature and has lower peak value .
Given ,
two aircraft rivets , one iron and the other copper , are placed in a calorimeter .
the initial temp of the calorimeter is 20 degC .
mass of iron = 30 g
initial temp of iron = 0 degC
Mass of copper = 20 g
initial temp of copper = 100 degC
Here copper has higher temp ,thus heat flow from Cu to Fe .
<h3>
What is heat flow ?</h3>
Heat flow is the movement of heat from higher temperature to lower temperature .
<h3>What is calorimeter ?</h3>
It is an object used for measuring the heat flow , heat capacity of a chemical reaction as well as the physical changes .
