1. What is the purpose of energy transfer during a change of state?
2. What does density measurement primarily involve?
3. How does the shape of the cooling curve during a phase change differ from that during sensible cooling?
Density — definition?
Mass per unit volume of a substance.
Cooling curve — analysis?
Shows temperature change and phase changes over time.
Change of state — role?
Energy transfer during phase transitions.
Density — formula?
ρ = m / V
Mass — unit?
Kilograms or grams
Water displacement — purpose?
Find volume of irregular objects
