States of Matter and Energy: Changes, Specific Latent Heat and Calculations
This video explains the relationship between energy and changes of states in matter. It discusses the different changes of state, such as melting, boiling, and condensing, and the fixed temperatures at which they occur. The concept of...

Weather Things: Water Phases
The cycle of water from the air to the ground to the oceans and back to the air never ends. Water is found in the air, in the ground, in rivers and oceans, and it's found as gas, liquid, and solid. As it moves though phases and locations...

The Law of Conservation of Matter
When you eat a burrito, where does all that matter go? What about when matter changes phases, does any matter appear or disappear? When we talk about this sort of stuff, reality sometimes goes against our intuition, so we'd better make...

PHYSICS - Matter - Specific Latent Heat
When a substance changes its state, heat energy is involved. This energy is used not to heat up the substance, but to separate the molecules from each other. This is known as specific latent heat. Specific latent heat is defined as the...
