If an electron is in an excited state it must lose energy when it falls to a lower state. What happens to the energy that is lost?
The energy that is lost when an electron falls to a lower state is emitted as a photon of light. This process is known as photon emission, and the energy of the emitted photon corresponds to the energy difference between the initial and final states of the electron.
The energy from food is not all absorbed by water using the experiment. Why?
Energy from food is not all absorbed by water because some of it is lost as heat during the burning process. The energy that is absorbed by the water is only a portion of the total energy content in the food. Additionally, some energy may be lost through inefficiencies in the experimental setup or due to factors like incomplete combustion.
How can we calculate the heat lost by the hot water in a given system?
To calculate the heat lost by hot water in a system, you can use the formula Q mcT, where Q is the heat lost, m is the mass of the water, c is the specific heat capacity of water, and T is the change in temperature. This formula helps determine the amount of heat energy transferred from the hot water to the surroundings.
How is calorimetry related to the law of conservation of energy?
The Law of Conservation of Energy states that energy is neither created nor destroyed but remains constant in a given system. Therefore, wouldn't calorimetry make use of it because the energy gained/lost by the water would cancel out the energy lost/gained by the substance and result in no change overall?

What is the scientific law that is the basis for the assumption that the heat energy lost by the a metal as is cools is equal to the heat energy gained by the water and the calorimeter?
The energy transfer within the system (between the water and the lead sinker) must obey the first law of thermodynamics. Meaning, "...that energy can not be created or destroyed, it can only be changed from one form to another or transferred from one body to another, but the total amount of energy remains constant (the same)." So due to the conservation of energy, the heat lost by the lead sinker is transferred to the water in equal amounts. We must assume here that the experiment is well controlled and there are negligible sources of heat transfer from unintended external sources.
When water at 0.c freezes is heat lost or gained?
As heat is a form of energy, it isn't lost or gained, it's just converted into another form of energy.
What happens to energy as it travels away from the sources?
Energy is lost
What happens to lost energy when water is created?
It forms covalent bonds between hydrogen and oxygen. The energy is released when the bonds are broken through electrolysis.
What happens to the energy that is not lost?
It goes to the sun
When 1 gram of water at 0 degrees Celsius freezes to form ice how many total joules of heat are lost by the water?
The heat lost by 1 gram of water at 0 degrees Celsius as it freezes to form ice is approximately 333.55 joules. This is the heat of fusion of water, which is the energy required to change the state of water from a liquid to a solid at its melting point.
What happens to energy as we move from step to step in a web?
Energy is lost
When energy is transferred from the air to the water what happens to most of the energy?
Most of it will end up in the water It travels through the water.
What happens if a cell has lost water?
it dies
When water freezes to form ice energy is?
When the liquid reaches its boiling point, it changes phase into a gas. The energy is being absorbed into breaking of the interparticular bonds. This is called the latent heat of vaporisation. In a pot of water that is boiling, the water is all at 100 degrees, however, only the water on the surface, or at nucleation sites, is able to change state into a gas. The steam that the water is turning into, is also at 100 degrees.
What happens to the energy level as you move up the energy pyramid?
10% of energy is lost as you move from 1 level to the next. So at the end 90% if the energy will be lost as heat.
When 1 gram of liquid water at 0 celsius freezes to form ice how many total souls of heat are lost by the water?
When 1 gram of liquid water at 0 degrees Celsius freezes to form ice, it releases 334 Joules of heat.
What happens to energy and matter when rowing a boat?
When rowing a boat, the rower converts chemical energy from their body into mechanical energy to propel the boat forward. As the oars move through the water, they displace water molecules, transferring some of their kinetic energy to the water. Some energy is also lost as heat due to friction between the oars and the water. Overall, energy is conserved, but some of it is dissipated in the form of heat.
