combustion
The heat of fusion refers to the energy required to change a substance from a solid to a liquid at its melting point. For water to change from ice to liquid water, heat needs to be added, making the heat of fusion a positive value.
Thermal (heat) energy must be added or removed in order to cause a change of state.
The liquid will boil.
When fire burns logs, a chemical change is taking place. The heat from the fire causes the wood to undergo combustion, which is a chemical reaction that breaks down the wood's molecular structure and releases energy in the form of heat and light.
Three signs of a chemical reaction include the release or absorption of heat, a change in color, and the creation of a gas or a precipitate.
Endothermic reactions require energy to be absorbed in order to take place. This means that the reactions absorb heat from their surroundings in order to proceed.
burning of wood
Heat required to have such a change of state is called latent heat. If L J/kg is the latent heat per kg of water then for M kg of water we need M* L joule of heat energy
It will change into a gas.Adding heat to or removing heat from a system may result in a temperature change and possibly a change of state. A liquid substance needs heat added to it in order to enter a gaseous state. If enough heat is added to a liquid substance it will change into a gas.
Not unless it is low of oil.
The heat energy in the milk had to be removed in order to change the phase of milk.
It needs to be added, in order for condensation to take place you have to have both cold and warm temperatures. For example, if you have ice water you usually have condensation because the ice and the air outside the glass mix and make condensation.

BECAUSE IN ORDER TO HEAT UP THE FOOD IT NEEDS TO GO SLOWLY TO GET THE TRUE HEAT!
A change of phase takes place at a constant temperature and pressure. During a change of phase, the substance absorbs or releases latent heat without a change in temperature.
Thermal (heat) energy must be added or removed in order to cause a change of state.
because by definition heat capacity is how much heat the substance needs to change its temperature by 1 degree. It "stores" heat and delivers it back slowly. It has nothing to do with heat resistance which is how much heat it allows through it.
