Answer:
C) O, C, H, N
Explanation:
Roughly 96% of the mass of the human body is made up of the four elements which are carbon, oxygen, hydrogen and nitrogen.
The elements, oxygen and hydrogen are found predominantly in water, which makes up 60% of body's weight approximately. Element carbon is synonymous with life. The central role of the element, carbon is due to the fact that the carbon has 4 bonding sites which allow the element for the building of long and the complex chains of molecules. Nitrogen is found in the organic molecules, including the amino acids which make up proteins, and nucleic acids which make up DNA.
Answer:
Li
Explanation:
The phenomenon of wave particle duality was well established by Louis deBroglie. The wavelength associated with matter waves was related to its mass and velocity as shown below;
λ= h/mv
Where;
λ= wavelength of matter waves
m= mass of the particle
v= velocity of the particle
This implies that if the velocities of all particles are the same, the wavelength of matter waves will now depend on the mass of the particle. Hence; the wavelength of a matter wave associated with a particle is inversely proportional to the magnitude of the particle's linear momentum. The longest wavelength will then be obtained from the smallest mass of matter. Hence lithium which has the smallest mass will exhibit the longest DeBroglie wavelength
Answer: D
Explanation:
Because at temerature at 25 and 50 is
to low for a compound to evaporate as gas because the bioling point is 100.
Your system could not cool as effectively as it should due to refrigerant leakage. Your home cannot reach the target temperature due to your air conditioning system. However, it may also result in higher monthly energy costs.
<h3>What is the temperature called?</h3>
Temperature is a unit used to represent hotness or coolness on any of a number of scales, including Celsius and Fahrenheit. According to temperature, heat energy will naturally move from a hotter (body with a high temp) to a colder (body with such a lower temperature) (one at a lower temperature)
<h3>What are the 4 types of temperature?</h3>
- The most widely used method of measuring temperature in the United States and several Caribbean regions is the Fahrenheit scale.
- Celsius Scale.
- Kelvin Scale.
- Rankine Scale
