What does the lantent heat of vaporization measure?
the amount of heat required to change the state from liquid to vapour of unit mass without changing the temperature
Does the speed of sound in water change with a temperature change?
yes it is changing. It's increasing with the temperature.
How does changing the temperature of solutions affect the amount of voltage that is going to be produced in votaic cell?
Changing the temperature increases the change in energy.
How do you change an object's density?
You have two choices: -- Somehow increase or decrease its mass without changing its volume. This is quite difficult. -- Somehow either expand it into a greater volume or squeeze it into a smaller one, without changing its mass in either case. This is easy to do if the object happens to be a sample of a gas.
How can a matter change from solid state to liquid state and reverse the process?
At a unique temperature, called the "freezing point", for each pure substance at a constant pressure, a solid form of the substance can change from solid to liquid phase by absorbing heat energy from its environment without raising the temperature of the substance, and, at the same temperature and pressure, a liquid phase of the same substance, can solidify without changing its temperature if it can transfer heat energy to the external environment.
What is the energy required to change a substance from a solid to a liquid WITHOUT changing it's temperature?
magic of coarse!

What will change the density of an object?
Either a decrease or increase in temperature will change the density of an object.
What is the difference in specefic heat and latent heat?
Specific heat is the heat energy in joules required to rise the temperature of one kg of substance through one kelvin without a change in its state. But latent heat is the heat required to change the state of one kg of substance without change in temperature.
Can boiling temperature of an element change?
The boiling temperature of an element can change by changing the pressure.
How does a physical such as mass or texture change without causing a change in the substance?
Ice melts to water if the temperature is high enough. This would change the texture but not the mass. It is difficult if not impossible to change the mass without changing the substance.
How does a physical property such as mass or texture change without causeing change in the substance?
Ice melts to water if the temperature is high enough. This would change the texture but not the mass. It is difficult if not impossible to change the mass without changing the substance.

yes it is changing. It's increasing with the temperature.
Is changing direction really the same as changing speed?
No. It is possible to change direction without changing speed. However, it is not possible to change direction without changing velocity.
Why do stars seem to change their colors?
Because their temperature seem to change too
How do the area and perimeter of the area of a figure change when it's dimensions change?
The answer depends entirely on how the dimensions change. It is possible to change the dimensions without changing the perimeter. It is also possible to change the dimensions without changing the area. (And it is possible to change the area without changing the perimeter.)
