Answer:
The <u>water vapor</u> will have the greatest entropy at the triple point
Explanation:
At the triple point of water, which has the properties of 0.0075°C temperature and 6.11657 mbar pressure, solid ice, liquid water and water vapor exist together in a location
According to Professor Stephen Lower on LibreTexts website entropy is a measure the extent to which thermal energy is shared and spread in a system
The change in entropy, ΔS = ΔH/T
The heat change in = 6.01 kJ/mol
The heat change in vaporization, = 45.05 kJ/mol
The heat change in sublimation, = 51.06 kJ/mol
Therefore, the entropy of the water vapor > The entropy of liquid water, > The entropy of the solid ice,
The portion with the highest entropy at the triple point is the water vapor
The water vapor will have the greatest entropy at the triple point
Answer:
B. sugar + oxygen → carbon dioxide + water + energy
Explanation:
Energy is that which sustains living organisms, so as to perform various activities. One of the processes by which living organisms produce energy is by respiration.
Respiration involves the breathing-in of oxygen and breathing-out of carbon dioxide as a waste. The oxygen helps in breaking down molecules of carbohydrates e.g sugar in the system of living organisms into energy, carbon dioxide and water.
This process is well represented by the equation in option B.
Systolic pressure is measured when the heart beats and the muscles are contracted. Diastolic Pressure is to measure the pressure on blood vessels when the muscles of the heart are relaxing.
<h3><u>
Explanation:</u></h3>
Blood pressure is the pressure that is put on blood vessels and the heart muscles when it is pumping blood. The blood pressure can be categorized as high and low. Both of them come with medical consequence and require attention and treatment.
The measurement of blood pressure contains two values:
Systolic Blood Pressure: When the blood is being pumped through the heart, a certain amount of pressure is applied on the arteries and contracted muscles of the heart. The pressure is measured to check if a person has a risks of heart strokes or attacks as well as kidney failures.
Diastolic Blood Pressure: When the blood is being pumped through the heart, a certain amount of pressure is applied on the blood vessels when the muscles are relaxing. The pressure is measured to prevent lack of oxygen that may cause severe damage to brain, heart and normal functionality of the individual.
Answer:
108.33 grams.
Explanation:
Given that,
Mass of a egg, m = 65 g
Volume of an egg, V = 60 cc
We need to find the mass of the salt dissolved in 100cc of water so that egg just float in water.
The density will remains constant,
So, the required mass is 108.33 grams.
Answer:
light waves can travel in vacuum but sound waves require a medium to travel
also light waves are electromagnetic waves while sound waves are mechanical, light waves are transverse waves while sound waves are longitudinal waves
