Answer:
- Both accurate and precise.
Explanation:
The experimental data is characterized as the data that is generated through a specific test or measurement with the purpose of analysis or evaluation. As per the question, the minuteness of the given data(29.27, 29.32, and 29. 27)most aptly describes that the experimental data collected by the student possesses 'accuracy and precision' apt and specific. It would yield the most worthy and reliable conclusion. 
 
        
             
        
        
        
Waters high heat capacity is a property focused by hydrogen bonding among water molecules.When heat is absorbed,hydrogen bonds are broken and water molecules can move freely.When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy
        
             
        
        
        
  The volume that  will  be occupied at 735  torr and 57 c  is  23.12 L
  <u><em>calculation</em></u>
- <u><em> </em></u> At STP   temperature=273 k  and  pressure=760 torr
- <u><em> </em></u>by use of combined  gas formula 
that is P1V1/T1= P2V2/T2
where; P1 =760 torr
            T1= 273  K
            V1= 18.5 L
           P2= 735 torr
          T2=  57+273= 330 K
           V2=?
- by making   V2 the formula of subject
      V2= T2P1V1/P2T1
        V2=  [(18.5L  x 330 k  x 760 torr)/(735 torr x 273 k)]= 23.12  L
 
        
             
        
        
        
Answer:
a mixture in which the composition is uniform throughout the mixture.
Explanation:
 
        
                    
             
        
        
        
For the first one the pattern is multiply the previous number by five as you see 1 x 5 = 5 and so on. To keep adding to it you would do
125 x 5 = 625     625 x 5 = 3125    3125 x 5 = 15625
Now for the second one the pattern is divide the previous number by three as you can see 2187 / 3 = 729 and so on. To keep going you would 
81 / 3 = 27       27 / 3 = 9        9 / 3 = 3
I hope this helps you and if you have anymore questions i'll be  glad to answer them.
