Because if you have a liquid then you need a glass to keep it together and when it is a solid it is already together so you don't need to do anything
I might not be right but I think the empirical formula is NO2
Answer:
C.
Explanation:
It’s particle boiling point because the atoms are moving fast around the particle as possible, so there for its C..
Answer:
The correct answer is 333.8 J
Explanation:
Ice (water in solid state) melts at 273 K (0ºC). During the phase change from solid to liquid, water absorbs 6.01 KJ per mol until it melts completely. To calculate the heat absorbed, we first have to convert the mass of water (1 g) to mol by using the molecular weight of water (H₂O):
Molecular weight of water= 2 x molar mass H + 1 x molar mass O
Molecular weight of water= 2 x 1 g/mol + 16 g/mol= 18 g/mol
mol ice= = 0.055 mol
heat= 0.055 mol x 6.01 KJ/mol= 0.3338 KJ
Finally, we convert KJ to J (1 KJ= 1000 J so we multiply by 1000):
0.3338 KJ x 1000 J/1 KJ= 333.8 J
