What change that needs heat in order to take place?
An example of a change that requires heat to take place is melting. When a solid substance is heated, the heat energy causes the particles to move faster and overcome their attractions, resulting in the solid turning into a liquid.
When are the quantites molar enthalpies of fusion and molar enthalpy of vaporation used?
Fusion refers to the phase change from liquid to solid (or vv) and vaporization refers to the phase change from liquid to gas (or vv). Heat is either absorbed or released from the substance when these events occur. We use the molar enthalpies to calculat exactly how much heat is transferred during these processes. Ex .. If we are to boil (vaporize) 3 moles of some substance with a known molar enthalpy of vaporization of 120 KJ/mole then we multiply. 3 moles x 120 KJ/mole = 360 KJ of energy is needed for the vaporization to take place.
What must be true for metamorphism to occur?
the process must take place underground~ apex
What is earths solid surface?
Take a walk outside. Then you will be walking on the Earth's solid surface.
Why is it not possible to electrolyse a solid substance?
It is not possible to electrolyze a solid substance because in order for electrolysis to occur, the substance needs to be dissolved in a liquid or molten form to allow for the movement of ions. Solids do not allow for this movement of ions required for electrolysis to take place.
Does Metamorphisn take place in the solid state with or without fluid activity?
Metamorphism can take place in a solid state. The metamorphism can take place with or without any types of fluid activity, although, the majority is done with fluid activity.
Where does conduction take place liquid or solid?
Conduction takes place in liquids and gaz's
When you fry an egg does a chemical change take place?
Yes, it turns to a solid and denaturation takes place.
What does a substance changed into when chemical change take place?
The reactants are changed in products having new chemical composition.
Where does Metal Gear Solid 3 take place in?
Russia during the 1960s
What processes take place when igneous rocks are changed to sedimentary?
compacting and cementing

When a rock is placed in a container will it take on the shape of the container?
No, rock is a stable solid whose shape can only be changed by cutting, eroding, or grinding.
Why does capoeira take place on the beach?
Loose sand doesn't hurt as much as solid ground when you fall.
How would the past of changed if Pearl Harbor did not take place in history?
The US might not have entered into WW2.
Does solids take a definite amount of space?
Provided one does not place the solid in extreme gravity fields, yes.
What is the effect of increasing the surface area of a solid?
It exposes more of the solid to whatever you want to mix it with so that whatever you are doing, whether it be a physical or chemical change, will take place more rapidly.
