Glass starts out as a mixture of mostly solid sand particles. However, in order to mold or blow glass, the particles must change phase to the liquid state. How can the sand's state be changed?
Responses
a. by increasing the density of the sand system to strengthen bonds between solid particles and increase freedom of motion
b. by adding a lot of heat to the sand system to weaken bonds between solid particles and increase freedom of motion
c. by decreasing the mass of the sand system to weaken bonds between solid particles and decrease freedom of motion
d. by removing all the heat from the sand system to strengthen bonds between solid particles and decrease freedom of motion
