This is because gas particles are free to move as they are not held in place by strong molecular forces while particles in a solid are
The direction of heat flow is from surroundings to system (air to ice), the dry ice is subliminating.
Answer:
76.5g KCl/74.55 grams per mole Kcl = x
molality= x/.085 kg H2O
Explanation:
well remember molality is moles of solute/kilograms of solvent. So it's the moles of KCl over 85 g of h20 converted into kg. if this makes sense.
Answer: 50 degrees Celsius is hotter than 50 degrees F. 50 degrees Celsius is half way between freezing and boiling
