Why is the transfer of energy and matter in a food chain only about 10 efficient?
Because 90% is released into the environment asheat...............i think..............
What is always loss during a transfer of energy?
ENERGY
The transfer of heat between two objects touching is called?
When a cold object and a hot object are in direct contact (touching) heat will be transferred through thermal conduction. Normally, heat transfer processes are categorized as thermal conduction, radiative transfer or convection. Heat transfer through thermal conduction is the direct transfer of kinetic energy from one molecule to the nearby molecules. Because temperature is directly proportional to kinetic energy, interactions between neighboring particles exchange energy and that exchange energy gradually works it way from the higher temperature regions to the lower temperature regions. The process of the temperature becoming the same is called thermal equilibration. Convective heat transfer occurs in fluids. If a gas, liquid, or other fluid, changes in fluid density change the buoyancy and will cause fluid to flow (a process called convection) and the heat contained in the warmer fluid is transferred to a new location by the physical movement of the fluid. Radiative transfer occurs when a hot object radiates electromagnetic energy. While the sun is an obvious source of electromagnetic energy, it is also generated in smaller amounts by any object. The hotter objects radiate more electromagnetic energy and the cooler objects absorb it. This radiative transfer is important but not as noticeable usually as the other two. It does occur between objects whether they are in direct contact or not, but is usually so small as not to be important of the objects are touching.
In what way is energy unable to transfer directly?
Energy is unable to transfer directly in the form of heat between two objects that are not in physical contact with each other.
Energy transfer by convection is usually restricted to what type of substance?
Energy transfer by convection is usually restricted to fluids, such as air or water. These fluids can transfer heat through the movement of their particles, leading to the transfer of thermal energy.
What is the reaction in which energy is released?
A reaction that releases energy is usually termed exothermic reaction. Energy is usually released as heat.
Why is work considered to be the transfer of energy?
Work is considered the transfer of energy because when a force acts over a distance, it can transfer energy to an object, causing it to move or change its position. This transfer of energy is known as doing work on the object. The work done on an object is directly proportional to the force applied and the distance over which the force is exerted.
What is the relationship between energy transfer and temperature change?
Energy transfer and temperature change are directly related. When energy is transferred to a substance, such as through heating, the temperature of the substance increases. The amount of temperature change depends on the amount of energy transferred and the specific heat capacity of the substance.
What is energy and how is the ability to do work related to it?
Energy is the capacity to do work. Work is the transfer of energy from one object to another, resulting in a change in the object's motion or position. In other words, the ability to do work is directly related to the presence and transfer of energy.
Can Energy be measured directly with a calorimeter?
Yes, energy can be measured directly with a calorimeter by measuring the heat released or absorbed during a chemical reaction or physical process. Calorimeters are designed to isolate the system being studied and measure the heat transfer accurately, allowing for the determination of energy changes.
How does changing the thermal energy in a system affect its overall temperature and heat transfer?
Changing the thermal energy in a system directly impacts its temperature and heat transfer. Increasing thermal energy raises the temperature of the system, leading to more heat transfer. Conversely, decreasing thermal energy lowers the temperature and reduces heat transfer within the system.
Is the transfer of energy called?
The transfer of energy is called Energy Transfer
How is energy and work related?
Energy is the ability to do work, and work is the transfer of energy. When work is done on an object, energy is transferred to that object, causing it to move or change. The amount of work done is directly related to the amount of energy transferred.
What is usually released in a combustion reaction?
energy
Do reactions always involve a transfer of energy?
Yes, reactions typically involve a transfer of energy between molecules. This transfer can result in breaking or forming chemical bonds, leading to changes in the energy of the system. Whether energy is absorbed or released depends on the specific reaction and its thermodynamic properties.
