I need help filling this blank.
The difference between a "cool" solid and a "hot" solid is that the particles vibrate __________ in the cool solid. Would "freely" fit the blank?
The difference between a solid and a liquid at the same temperature is that the particles of the liquid can move ____________ each other. Would "faster fill the blank?
Car bodies can also rust, which is called_________, a __________ property.
I don't know about the first one, but would the second blank be physical?
more ; around ; iron oxide, chemical
For the first sentence, in a "cool" solid, the particles vibrate __________. To fill in the blank, we need to understand the behavior of particles in a solid when it is cooled. When a solid is cooled, its particles have lower energy levels, causing them to vibrate less. The correct word to fill the blank would be "less" or "slower," as the particles vibrate at a slower pace in a cool solid.
In the second sentence, the blank needs to be filled with a word that describes the movement of particles in a liquid compared to those in a solid at the same temperature. In a liquid, the particles possess more energy compared to the particles in a solid, enabling them to move more freely. The correct word for the blank would be "more" or "freely," as the particles in a liquid move more freely compared to those in a solid.
Regarding the third sentence, car bodies can rust, which is called_________, a __________ property. The process of rusting is a chemical reaction that occurs when iron or steel is exposed to air and water, leading to the formation of iron oxide. The correct word to fill the first blank would be "rusting," as it is the term used to describe the process. For the second blank, rusting is a chemical property, as it involves a change in the chemical composition of the metal due to the reaction with oxygen and moisture.
