What else can I help you with?
Is it true or false that solids can go directly into the gas phase without becoming a liquid first?
False. Solids cannot go directly into the gas phase without becoming a liquid first. This process is known as sublimation, where a solid turns into a gas without passing through the liquid phase.
Acceleration is the change in distance over time True or false?
False. Acceleration is a change of speed or direction over time.
When you change direction are you accelerating true or false?
True. Acceleration is any change in velocity, including a change in direction. So when you change direction, you are indeed accelerating.
In physical change matter cannot change its shape true or false?
False. In a physical change, matter can change its shape without changing its chemical composition. Examples include melting, freezing, and dissolving.
Is this true or false in a chemiccal change other forms of energy cannot be changed to chemical energy?
False. In a chemical change, other forms of energy, such as heat or light, can be changed into chemical energy. This transformation can occur during reactions where energy is either absorbed or released as chemical bonds are broken or formed.
Sublimation is th change from a soild to a gas with out becoming a liquid first true or false?
True.
Sublimation includes melting True or false?
false
True or false the sublimitation is a change from solid to gas?
That statement is true.
Is it true melting is considered an sublimation change because energy is gained by substance as it changes stae?
Melting is a phase change in which a substance changes from the solid state to the liquid state. Sublimation is a phase change in which a solid moves directly into the gas phase. Both melting and sublimation are two types of physical change.
Freezing is a change of state true or false?
Yes, freezing is change of state, from liquid to solid. Freezing is a physical change, not a chemical change.
Is it true or false for A Change In State Is A Physical Change?
True. A change in state, such as from solid to liquid or gas, is a physical change because the substance's chemical composition remains the same and only its physical properties, like shape or state, change.
True or false a geometric solid has only length and width?
False
Is the crust earth's only solid layer true or false?
True or false: the crust includes BOTH dry land and the bottoms of the oceans?
True or false- in solid NaCL no molecules of NaCL exist?
true
In geometry a solid may exist in a plane true or false?
The statement is false.
Is Pluto manly made of gas true or false?
False. Pluto is solid.
True Or False Any value that is unknown or can change is a variable?
True.
