What type of scale is used to measure mass: a double pan balance or a spring scale?
What is a double-pan balance? It uses weights to measure mass. A spring scale uses gravity.

Define atom:
What is the smallest basic unit of matter?
400
Which is a physical property: Thermal conductivity or flammability?
What is thermal conductivity? Thermal conductivity measures the amount of heat an object holds. Doesn't change the object. Flammability may change the object as it is introduced to a flame.

What is the difference between mass and weight?
mass: the amount of matter in an object
weight: The gravitational force acting on an object's mass
