ENERGY
The mouse use some energy is used in respiration(loss as heat) and the others used as growth( which will then pass on to the cat)
a change of state
In long range,electric current can flow only when the wires are given high voltage.The voltage is about 20-30kV.eg.lightning. ---------------------------------------- Current of any voltage can flow in a wire. However, the larger the current is, the larger the resistance to flow and the greater the loss of energy during transmission. Therefore, to transfer the same amount of energy per second (power) without as much loss of energy due to resistance, current needs to be lowered by increasing the voltage since Power = Current * Voltage.
The heat energy absorbed by the colder object is roughly equal to the energy imparted by the warmer object (there is always loss), but the temperature change is based on the masses of the objects. If, for example, one gram of water at 60°C is mixed with one gram at 20°C, the mixture, ignoring losses, will be at 40°, there having been a heat energy transfer of 20 gram-calories. OTOH, if one gram of water at 60°C is mixed with one kilogram at 20°C, there will be a 40 gram-calorie transfer that will, again ignoring losses, result in the mixture being at about 20.04°C.
The rate of heat loss from the hot cup decreased during the experiment.
No, energy conversions always involve a transfer of energy from one form to another. Some energy will always be lost in the form of heat or other forms of energy during the conversion process, due to factors like inefficiencies in the system or resistance.
When energy is converted from one form to another, there is always a loss of energy in the form of heat. This is due to inefficiencies in the process, such as friction or energy transfer losses. This loss of energy is known as the second law of thermodynamics.
Energy may not transfer to the next trophic level due to inefficiency in energy transfer, loss of energy through metabolic processes, or energy being lost as heat during each energy transfer. Additionally, some energy may be used for movement or other activities that do not result in biomass production.
The type of energy that is always lost during energy transformations is usually heat energy. This is because some of the energy input is typically converted into heat due to inefficiencies in the system, leading to a loss in usable energy.
No, it is not possible to achieve 100% efficiency in energy transfer due to factors such as friction, heat loss, and resistance in the transfer process. Some energy will always be lost or converted into other forms, limiting the overall efficiency of energy transfer.
Usually some energy is wasted, yes. Energy is not "lost" in the sense of conservation of energy; energy is always conserved. However, useful energy gets converted into unusable energy all the time.
Heat
wasteful energy is energy that is niot uyse and cannot be used again, it is also unuseable to be reused. Wasteful energy is energy that is also energy that can not be use over and over, :), the way energy works is the way it works, but sine energy doesnt want to work or be reused. :O
Machines are never 100% efficient due to factors such as friction, heat loss, and mechanical limitations. Some amount of energy will always be lost during the transfer or transformation process, making it impossible for a machine to achieve perfect efficiency.
The movement of energy from one system to another can impact the overall efficiency of the systems involved by potentially causing energy loss or inefficiencies during the transfer process. This can result in a decrease in the overall efficiency of the systems as some energy may be lost as heat or through other forms of energy dissipation. It is important for systems to be designed and operated in a way that minimizes energy loss during transfer to maintain optimal efficiency.
Energy may be lost as it is transferred between different forms due to factors such as heat dissipation, friction, or inefficiencies in the conversion process. This loss is typically in the form of heat which is a less useful, more disordered form of energy. The Second Law of Thermodynamics states that in any energy transfer or transformation, some energy will be dispersed or lost in the form of heat.
Some energy is always lost in the form of heat due to inefficiencies in the conversion process. This loss is known as thermal energy or heat loss.
