The root mean square speed of I20 compared to Brzog, at the same temperature, would be B) less C) the same D) impossible to predict A) greaterExplanation / Answer
Q 1 )
CO2 has more vander force so CO2 is with greater intermolecular interaction
Due to more electronegativity difference in HF . HF is with greater intermolecular interaction
Li+ due to low ionic size
CF4 (more electronegative difference
C6H6
Trans C2H2Cl2
Q 2 :
Given :
Specific heat of water = 4.184 J / g C
Initial temperature of iron = 100 deg C
Initial temperature of water = 20 deg
Final temperature = 23 deg C
Solution
Lets assume 100 g each
q = m C delta T
m = mass in g , C is specific heat , Delta T = Tf-Ti
Iron is at higher temperature than water so it gives heat to water
-q (iron) = q (water )
Lets plug given values
-(100 g * specific heat of iron * (23.0
