What must occur to the heat energy of an object in order of a phase change of the state of matter?
heat is added
Do you need to increase or decrease the amount of heat energy to change a solid to a liquid?
Thermal (heat) energy must be added or removed in order to cause a change of state.
Why does evaporation require that heat energy be added to a substance?
Heat is energy the substance needs to change it's state of matter (the more energy a substance has the higher it's temperature)
What phase change from liquid to gas will take place if you add energy equal to the heat of vaporization?
The liquid will boil.
In order to evaporate water needs what?
Exposure to the atmosphere will cause water to evaporate. The higher the atmospheric temperature the faster the rate of evaporation.
What state will most likely result if heat is added to a liquid?
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.
Why does energy change?
energy changes because the energy needs to transfere in order to become heat energy, sound energy.
What chemical change needs heat?
burning of wood
How much more heat needs to be added to water at 100 degrees centigrade in order to change it to steam?
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
What type of heat transfer takes place when a furnace heats up an entire room?
So in order for a furnace to heat up in the first place, there needs to be a fuel or substance that heats or absorbs heat. This can be gas, coal, or charcoal. In addition, the fuel or coal, the fire or heat will begin to well heat, then heat will begin to spread. Causing heat, or humid to form in the room you are in. HOPE THIS HELPED:)))))
Will car over heat if it needs an oil change?
Not unless it is low of oil.
In order to change the phase of the milk what had to be removed?
The heat energy in the milk had to be removed in order to change the phase of milk.
In order to change the phase of milk what had to be removed?
The heat energy in the milk had to be removed in order to change the phase of milk.
Does heat need to be taken away or added in order for cendensation to take place?
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.
What must occur to the heat energy of an object in order of a phase change of the state of matter?
heat is added
Why disc in microwave oven rotates at slow speed?
BECAUSE IN ORDER TO HEAT UP THE FOOD IT NEEDS TO GO SLOWLY TO GET THE TRUE HEAT!
What kind of physical change requires heat?
Water needs to be heated to enter its gas phase as steam.
