Brinicles: Matter and its Properties

The amount of salt that can be dissolved in a given sample of water

• Density

• Brine

• Salinity

• Brinicles

An increase in salinity leads to an increase in

• pressure

• water

• density

• thermal energy

Salt breaks free from the freezing ice due to

• high freezing point

• lower freezing point

• difference in density

• difference in molecular structure

Density is defined as

• the amount of mass

• the amount of volume

• the amount of mass per pressure

• the amount of mass in a given space

The correct formula for density

• D = M/V

• D = V/M

• D = M/P

• D= V/P

What are the correct units for denisty?

• kg

• kg/L

• L/Kg

• L

The average kinetic energy of the molecules in a substance

• Heat

• Temperature

• Thermal Energy

• Density

The sum of the kinetic and potential energies of all molecules in a substance

• Heat

• Temperature

• Thermal Energy

• Density

The transfer of thermal energy from warmer to cooler objects

• Heat

• Temperature

• Thermal Energy

• Density

Which characteristic correctly describe the impact of thermal energy on particle motion?

• The increase in energy decreases the movement of particles leading to the transition from solid to liquid to gas.

• The decrease in energy increases the movement of particles leading to the transition from gas to liquid to solid.

• The decrease in energy decreases the movement of particles leading to the transition from gas to liquid to solid.

• The increase in energy increase the movement of particles leading to the transition from gas to liquid to solid.
