Is it true that A change of state requires the addition or removal of heat energy?
Yes, that's correct.
Does boiling require the removal of energy?
No. It takes energy to boil a substance.
What causes changes state of water?
Addition or removal of heat energy.
Does Freezing require the removal of energy?
yes because you will be losing heat
What changes only the physical state of water?
The addition or removal of heat energy.
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.
Does melting require the absorption of energy?
Yes, it does to change state
Which change of state requires the input of thermal energy?
Hi, by this I assume you mean that you want to know which changes of state produces heat (raise the air temperature) as this temperature change is the removal of energy from the system. (Also called an exothermic reaction).To remove energy from a change of state bonds must be formed between molecules therefore going from gas to liquid, gas to solid or liquid to solid are all exothermic and remove energy from the system.If you mean removal of energy from the air therefore decreasing air temperature then it is the other way around.
What are two changes in state the require the addition of latent potential energy?
Melting of solids and vaporization of liquids.
The addition or loss of thermal energy changes the arrangement of the particles during what?
a change of state
Why are cytosis affected by change in oxygen and diffusion is not?
Cytosis requires energy, and the production of energy depends on oxygen. Diffusion does not require energy.
Which of the changes of state shown in the figure require an increase in energy answers?
Evaporation uses energy to change from a liquid to a gas. Melting uses energy to change from a solid to a liquid. Condensation releases energy to change from a gas to a liquid. Freezing releases energy to change from a liquid to a solid.
