Answer:
Explanation:
From the information given:
Mass of carbon tetrachloride = 5 kg
Pressure = 1 bar
The given density for carbon tetrachloride = 1590 kg/m³
The specific heat of carbon tetrachloride =  0.84 kJ/kg K
From the composition, the initial volume of carbon tetrachloride will be:
= 0.0031 m³
Suppose  is independent of temperature while pressure is constant;
 is independent of temperature while pressure is constant;
Then:
The change in volume can be expressed as:





However; the workdone = -PdV

W = - 7.6 J
The heat energy Q = Δ h


Q = 84 kJ
The internal energy is calculated by using the 1st law of thermodynamics; which can be expressed as;
ΔU = ΔQ + W
ΔU = 84 kJ + ( -7.6 × 10⁻³ kJ) 
ΔU = 83.992 kJ
 
        
             
        
        
        
Answer:
3.089 L
Explanation:
From the given information, provided that the no of moles and the temperature remains constant;
 = 15.6 psi
 = 15.6 psi
 = ???
 = ???
 = 25.43 psi
 = 25.43 psi
 = 1.895 L
 = 1.895 L
Using Boyle's law:

 
        
             
        
        
        
True
Explanation:
The DNA is the structure in living organisms that encodes genetic information. 
DNA = DeoxyriboNucleic Acid. 
- The DNA is made up of a double helix structure of two strands. 
- It is made up of a phosphate group,deoxyribose sugar and four nitrogenous bases. 
- The DNA is contained in the nucleus of every cell. 
- Crick and Watson suggested the molecular structure of the DNA to be a double helix shape.
