Does the mean molecular speed change as much as the temperature as the water heat up?
Yeah - but remember the increase in temp is always on the kelvin scale. Proportions are related to zero kelvin.
Calculate velocity of a gas?
Gas velocity involves the variables of system temperature and molar mass of its molecules. Simplified, the velocity as a root-mean-square equals the square root of two-times the kinetic energy divided by molecular mass.
Does velocity of molecular movement decrease or increase with temperature?
The relationship between temperature and molecule movement is a direct variation. Whenever the molecule movement increases so does the temperature; when the molecule movement decreases so does the temperature. I hope that helps.
What changes a liquid or a solid to a gas?
usually a change in temperature.... OR PRESSURE Which all mean a change in entropy of the system
What property of a substance does the change in temperature indicate?
Change in temperature directly indicates a change in the mean amount of kinetic energy possessed by each particle. It also indirectly indicates a possible change in state, and a possible change in chemical properties too (chemical reactions often involve energy transfer in the form of temperature change).
Does mean molecular speed change as much as the temperature water heats up?
mean molecular speed varies as the square root of temp, so the temp has to change by a factor of 4 for the speed to change by a factor of two...hope I am interpreting your question properly

What is the random molecular of a substance is greatest when the substance is?
It is greater when the substance is at a higher temperature. This is because the mean square speed of the molecules of a system is proportional to thermodynamic temperature.
What does Molecular Motion mean?
When the temperature increases during a chemical or physical change the molecular movement increases. This means the molecular movement is faster. If the temperature decreases the molecular movement decreases. This means the molecular movement is slower.
Does the kinetic molecular theory need a temperature?
I would suppose so as without temperature there is no movement of molecules. That is what temperature is; the movement of molecules. Absolute zero in temperature would mean the complete stoppage of all molecular movement.
What is the vibration of an object?
If you mean molecular vibration than this is called "heat" and gives the object its current temperature.
What does it mean for an object to have constant speed?
the object's speed doesn't change
Is heat only transferred if there is no temperature change?
I am not quite sure what you mean. If heat is exchanged, there is usually a temperature change.
If the temperature changes does that necessarily mean it is a chemical change?
No.
What three things can acceleration mean?
Increasing speed, decreasing speed, and change of direction
The theoretical point at which all molecular motion stops is called?
"absolute zero" or 0 degrees Kelvin.
