Phase Change Engineering Internship

What is a 'Temperature Plateau'?

• A measure of how hot or cold something is

• A formal design that is supported by evidence

• A period in which there is no change in the kinetic energy or temperature of a substance as it undergoes a phase change

• Something that can be changed and may be measured
