Kelvin (K) is the only scale that has a numeral value assigned to absolute zero.
Answer:
<u>d) 1.8 atm</u>
Explanation:
<u>According to Boyle's Law,</u>
Here, we are given :
- <u>P₁ = 1.5 atm</u>
- <u>T₁ = 25°C = 298 K</u>
- <u>T₂ = 75°C = 348 K</u>
<u />
<u>Solving</u>
- P₂ = P₁T₂/T₁
- P₂ = 1.5 x 348 / 298
- P₂ = 522/298
- P₂ = <u>1.8 atm</u> (approximately)

Answer:
O2 is a covalent substance while NaCl is an ionic substance
Explanation:
In O2 molecule, the bond is between 2 oxygen atoms which are non - metals. Thus, this is a covalent bond since it involves 2 non metals.
Whereas, for the NaCl molecule, the bond is between a metal sodium (Na) and a non metal Chloride(Cl) and thus we can say this is an ionic bond.
Thus the difference is that O2 is a covalent substance while NaCl is an ionic substance.
