What 2 things must occur for work to be done?
Transfer of energy and something else.
Which property must be the same in order to stop the transfer of energy between two objects?
Temperature
How the light energy from the stove transformed into heat energy?
light energy is transfromed into heat becaues light is hot For visible light to transfer enough energy to heat some object, you must be talking about laser light. Infra red waves transfer heat because the bodies cells respond to this, infra red is not visible light but has slightly longer wavelengths (lower frequency)
What kind of heat energy is burning wood?
Burning wood is the process of converting chemical energy in the fuel into thermal energy. Heat transfer is the process of moving thermal energy from one object to another. There are different types oh heat transfer including radiation, conduction and convection. Basically, the wood burning is a spontaneous process, theoretically, but in order for the process to become under way something called the activation energy must be overcome, which means that an energy of that magnitude must be applied to the wood to get it burning (oxidising). This usually comes in the form of a spark or a flame from your lighter. So once you apply that activation energy from your lighter, the wood begins to burn, and the burning of the wood itself produces heat to propagate the process. So long as there is oxygen, fuel (such as wood or octane for example) and the initial spark, then you have fire!
Is it possible that no transformation of energy may take place even when a force is applied to a body?
Yes. Forces are constantly applied to objects; for an energy transfer (work) to occur, there must be a force AND movement: work = force times distance.
Is it true that cells must transfer the energy in lipids to ATP before the cells can use the energy?
Yes
What must a charge have to move and to transfer energy?
A path to follow and electric potential.
What must happen for carbon dioxide to sublimate at a given pressure?
Energy must transfer to the carbon dioxide from its surroundings

Temperature
Which property must be the same in order to stop the transfer of energy between two objects?
Temperature
How does the law of conservation of energy imply to an energy transfer?
Total amount of energy and mass in process must be conserved it may change to another type of energy but can not just disappear.
When hotter atoms c they transfer their energy to colder atoms?
Yes, hot atoms must transfer their energy to colder atoms to keep the atomic temperature and movement balanced, and to keep these atoms alive.
What kind of energy must be provided for an enzyme to function?
Activation
What is transferred through a medium?
Disturbances that transfer energy, or waves. Mechanical waves must have a medium to travel.
What happens for carbonate dioxide to sublimate at a given pressure?
Energy must transfer to the carbon dioxide from its surroundings
Does oxygen give us energy?
Yes, but not directly. Your mitochondria must "burn" hydrogen and oxygen to form water AND transfer that energy to ADP in order to form ATP, That energy you can use.
