By removing heat what happesn 1. a liquid changes to a solid. 2 a solid changes to a liquid. 3 a liquid changes to a gas. 4. a solid changes to gas?
1. a liquid changes to a solid. This process is called freezing, and involves the loss of heat.
What is latent heat of fusion of a solid?
It is the amount of heat (measured in the proper unit, say calories) required to change a unit mass (measured in the proper units, say gram) of a substance from the solid to the liquid state. This would also be the heat given out by a unit mass of the liquid when it changes to the solid state.
What does Heat transfer by convection requires to transfer heat?
A liquid - - - which changes density when heated, and A gravity field.
What change takes place in the liquid inside a thermometer when it is placed into somthing cold?
The liquid inside the thermometer "contracts" when it is placed into something cold. This means that it decreases in volume and increases in density. This is the reason that the thermometer can measure heat: the volume of the liquid inside the thermometer changes as a function of heat, and the amount of liquid in the "tube" of the thermometer changes as a function of volume. Because of this relationship, the level of the liquid in the tube of the thermometer changes as a function of heat.
Which state changes require heat and which gives off heat?
Change from solid to liquid to gas require energy. Change from gas to liquid to solid emit energy.
Describe the process of condensation When does condensation occur?
It occurs when a gas changes into a liquid. Heat is given off.
When does matter change state?
when water gains or loses heat, it changes its state. When liquid water gains heat, it changes its state from liquid to gas. It becomes water vapor. When solid gains heat, it melts an changes its state from solid to liquid. When gas loses heat, it condenses into liquid. Gas, to liquid. When liquid loses heat, it becomes solid

What are the various possible changes when heat is applied to a given object?
Physical change - changes state, solid to liquid and/or liquid to gas. Chemical change - for instance, oxidises if present in air, but there are limitless possibilities.
Does heat changes gas to liquid?
No
When you cool down a liquid it becomes a?
When you heat a liquid and it changes phase it becomes a solid.
When heat is taken away from water it changes from a liquid to what?
Water changes to a solid, ice, when heat is taken away from it. You can think of putting water into the freezer. Since the freezer is cold, heat flows out of the water making it become ice cubes.
When you heat liquid and it change phase it become a?
When you heat a liquid and it changes phase it becomes a solid.
What During the process of gas loses heat and changes into a liquid.?
Gas changes into a liquid during condensation.
When liquid changes to solid here is heat?
When this happens,the liquid loses all its heat & becomes solid.
Is heat taken away or added in evaporation?
Taken away. As a liquid evaporates, it loses heat to the atmosphere.
What does a liquid become when you heat it and it changes its phase?
A heated liquid will become a gas.
