Answer : Option A) X: High and Y: High
Explanation : When comparing plasma with solids it is seen that solids are more denser than plasma and has less kinetic energy as compared to plasma.
So among the difference plasma will have high kinetic energy and solids will have high density in comparison with each other.
Answer:
The devise used to convert thermal energy to mechanical energy are called heat enignes
the following answer is H20
Answer:
°C = -33.39 °C
K = 239.76 K
Explanation:
- °C = ( °F -32 ) / 1.8
- K = 273.15 + °C
⇒ °C = ( -28.1 - 32 ) / 1.8
⇒ °C = - 33.39 °C
⇒ K = 273,15 + (-33.39)
⇒ K = 239.76 K
Answer: Thus percentage purity of sodium carbonate is 60.83%.
Explanation:

Volume of the HCl solution ,V = 15.55 mL= 0.01555 L
Concentration of HCl solution ,C= 0.1755 M
Moles of HCl in 0.1755 M solution = n


According o reaction 2 moles of HCl reacts with 1 mole of sodium carbonate.
Then n moles of HCl will react with:
of sodium carbonate.
Mass of
of sodium carbonate:

Mass of the sample given= 0.2377 grams
Mass used up in reaction = 0.144585 g
percentage purity= 
Thus percentage purity of sodium carbonate is 60.83%.
