When you add energy to a substance it's temperature will remain constant if there is a change of state from solid to liquid or liquid to gas. The energy added is absorbed in changing state; known as latent heat of fusion (melting), or latent heat of vaporization. For some substances a similar effect can occur if there is a chemical change.
There are also situation where an influx of energy will cause a decrease in temperature. One such is drinking water stored in a canvas container. Sunlight causing the wet canvas to evaporate some of its water will effect a decrease in the temperature of the stored water.

Wiki User
∙ 9y agoYes. Adding heat will increase temperature.
Wiki User
∙ 13y agoYes. As the speed of atomic and molecular motions increase so does their energy-of-motion, or Kinetic energy.

∙ 7y agoNo. The temperature does not increase during a phase change (solid to liquid; liquid to gas) even though energy (heat) is being added to the system.

What is the changes in kinetic energy as a substance is heated to its melting point?
The kinetic energy increase.
Does radiation require a heated liquid to transfer energy?
No. radiant energy (including heat) can pass though a vacuum.
What does an increase of temperature do to the KE of a liquid?
It increases the Kinetic Energy
When enough energy is GAINED a liquid will?
its vapourization rate will increase
How does the addition of heat to a liquid affect its average kinetic energy?
It would increase its average kinetic energy which would be apparent by an increase in temperature.
Radiation require a heated liquid to transfer energy?
Radiation does not require a heated liquid to transfer energy.
How can a liquid be heated?
When a liquid is heated the particles increase speed and then move farther apart. Also the liquid and bubble up.
When does the energy of water increase?
The energy of water can increase if it is heated up, if it is placed under more pressure, if it changes phase, or if it flows faster. In phase change, increase of water's energy happens from: solid phase to liquid phase (melting), from solid phase to vapor phase (sublimation), and from liquid phase to vapor phase (evaporation). Increase in altitude also increases its potential energy.
What happens to a particle in a liquid when heated?
The Particles Vibrate , Causing the liquid to evaporate leaving behind a gas. ! Sophie :)
When a given quantity of a liquid is heated the mass quantity will vary and how?
The volume will increase, since most liquids tend to expand when they are heated. The mass will NOT increase, for most practical purposes - since there is something called "conservation of mass". However, the energy added to the liquid is equivalent to a small amount of mass; this is insignificant for most practical purposes.
Why does the liquids rate of evaporation increase when the liquid is heated?
because
What happens to the density of a fluid when it is heated?
When the liquid molecules are heated, they move faster so the liquid boils and some molecules becomes gas molecules. When the liquid molecules are heated, they move faster so the liquid boils and some molecules becomes gas molecules.
What happens when a liquid is heated-?
The kinetic energy content increases and the speed of its particles increases.
What happen to the average energy of the molecules in a substance when it is heated?
They increase in energy.
What is the transfer of energy by motion of heated gas or liquid?
this energy is conduction or thermal energy
What does most matter increase in when heated?
entropy and energy
Why when the liquid is heated does the temperature not always increase?
If the liquid is heated to its boiling point, at which point it undergoes a physical change called vaporization, its temperature will not increase until the physical change is complete. This is due to the heat energy being used to break intermolecular bonds, such as hydrogen bonds, so that the physical change can take place.
