500
When particles are not arranged in a regular pattern
What is an amorphous solid?
500
When temperature of a gas is increased at constant pressure, the volume increases states this scientist's Law

500
When a graph of two measurements forms a curved line and the relationship is non-linear
What is varied inversely?
500
The principle that states that every chemical and physical change starts and ends with the same total amount of energy
What is the law of conservation of energy?
500
When a solid turns to gas without passing through the liquid state
What is sublimation?
