Front

What happens to the mass of a system when a reactant is a gas and the container is sealed?

Back

The mass is conserved and remains the same as long as the container is sealed.

Front

What happens to the mass of paper when it is burned?

Back

The mass is transformed into ash and gases, but the total mass remains constant.

Front

What occurs to the motion of particles as a substance is heated?

Back

The particles move faster as the substance is heated.

Front

What occurs to the motion of particles as a substance is cooled?

Back

The particles move slower as the substance is cooled.
