Answer:
B. The volume of the liquid should be measured before it is heated.
Explanation:
A student made serious mistake that he did not measure the volume of the liquid before heating.
The scientific experimentation along with care and attention need a proper protocol which a scientist needs to follow to get the results.
The initial hypothesis of the student shows that he wants to know the change in volume, so it is inevitable to calculate the initial volume to know the difference after the completion of experiment.
<em>All other options seem less appropriate than Option B, therefore B is the right answer.</em>
I hope it help!
You multiply 15,000 by .1, which equals 1,500. Then you add that to 15,000. This equals 16,500. That is your answer.
The correct option is:
B) lipid
Explanation:
A lipid is a biomolecule that is solvable in nonpolar solvents. Non-polar solvents are typically hydrocarbons used to melt another naturally happening hydrocarbon is.Any of a large group of organic mixtures that are oily to the touch and difficult in water. Lipids comprise fatty acids, oils, waxes, sterols, and triglycerides. They are a source of stored energy and are an element of cell membranes.
Answer:
All are true of the movement of Earth's atmosphere except :
d. Warm air is less dense than cool air so it tends to sink towards the Earth's Surface.
Explanation:
- When gases heat up, their volume increases and density decrease.
- A decrease in density causes a substance to become lighter.
- Thus, when air warms up due to heat from the sun its density decreases and it gets lighter.
- So, it will move up.
- The Cooler air in turn is denser and heavier so it will sink towards the Earth's surface.
- Hence, the statement d , which states that 'warm air is less dense than cool air so in tends to sink towards the Earth's Surface' is FALSE.
For the answer to the question above, one of the side effects of carbon in the environment is the global warming or Climate change. The Carbon dioxide traps the heat of the sun from escaping the atmosphere. This results to increase in global temperature which causes the ocean water to evaporate than usual and creates super typhoons.
