melting boiling (or) evaporation
(solid)------>(liquid)----->(gas)
<------ <-----
solidifying condensation
(ice)-------->(water)----->(vapour)
heat
solid--> liquid(Temperature increase)
liquid-->gas(Temperature increase) gas--> liquid(Temperature decrease)
liquid--> solid(Temperature decrease) Temperature changes(ice to water)--> state doesn't change
State changes(ice to water)--> temperature doesn't change
If Ice(-10 degree celsius) melts, it goes to 0 degree celsius but state doesn't change
After ice is melting, the temperature changes but the state doesn't change. After it reached 100 degree celsuis, the liquid evaporates or boils( the state changes)
Difference between boiling and evaporation
1. Evaporation takes place at any temperature, boiling takes place at fixed
temperature.
2. Evaporation occurs at the surface of the liquid, boiling occurs throughout the
liquid. 3. Evaporation does not form bubbles and boiling forms bubbles. While melting--> temperature constant
ice melting to water = 0 degree celsius Mass(instrument)--> balance
Volume(instrument)--> can measure volume for regular solid but
for irregular solid, first, fill with water, then put irregular object in the measuring cylinder in which there is an increase in volume.
