No. the temperature doesn't change, the substance does.
yes the temperature of a substance alway changes from liquid to gas because it needs more kinetic energy for a liquid to go to the gas state breaking the intermolecular forces

Which is true of a melting point and a boiling point?
Melting point: at this temperature a solid become a liquid.Boiling point: at this temperature a liquid become a gas.
True or false as a star ages its internal composition changes as a result of rising temperature?
true
When an acid reacts with metal the liquid changes colour to green?
True
Saturated fats tend to be solid at room temperature while unsaturated fats tend to be liquid oils at room temperature true or false?
it is true
What effect does the speed of molecules have of matter?
The speed of the particles in a substance changes when the temperature changes. Heating the substance causes the particles to speed up, while cooling causes the particles to slow down.
Would it be true to say that solidfication is from a liquid to gas?
False. Solidification when a substance that is in a liquid changes phase to a solid.
True or False- Energy is transferred as heat from a substance at high temperature to a substance at low temperature?
true
True or false when ice changes to a liquid it asorbs energy?
true, when ice changes to a liquid it asorbs heat energy .
True or false temperature is a measure of how hot or cold a substance is?
How hot or cold a substance is the temperature, so a thermometer will measure it.
A trivia question When evaporating a liquid you add heat until the liquid reaches a temperature at which it changes to bubbles of gas below its surface. Is this True or False?
the question isThe transmission of heat requiring the movement of a liquid or a gas is....the answer is (C.convection)
Is liquid helium a true substance?
Yes it is. Helium will be liquid below -268.93 °C
Is it true are false that a physical change of a substance changes its chemical makeup?
true
Does evaporation change a gas to a liquid?
Evaporation is where a liquid turns into a gas. But only the surface of the liquid. If the whole liquid is in the process of turning into a gas, we call it boiling. If a solid is turning into a gas, we call it sublimation.
Which is true of a melting point and a boiling point?
Melting point: at this temperature a solid become a liquid.Boiling point: at this temperature a liquid become a gas.
When a substance loses or absorbs energy its temperature can change true or false?
Very true.
Is freezing point of a substance is equal the melting point of the same substance?
The freezing point and the melting point both refer to the temperature at which a substance changes between a liquid and a solid state. If other conditions remain the same, the temperature at which a substance freezes is the same temperature at which it melts. Water is an every day example with a freezing point of 0C, the same temperature as it will begin to melt. Other substances such as metals have significantly higher melting points from around 200C to more than 3000C.
When water changes from a gas to a liquid it condenses?
Yes that is true
