Does wind determine thermal energy?

Wind power is converted to thermal energy directly to utilize thermal energy storage. Economy of WTES is better than wind power with backup thermals.

What factors affect thermal energy transfer?

The rate at which an object transfers energy by heating depends on: the surface area, volume and material of the object and the nature of the surface with which the object is in contact. The bigger the temperature difference between a body and its surroundings, the faster the rate at which heat is transferred.

What factors determine how much thermal energy is needed to warm a cup of soup?

Experiments show that the transferred heat depends on three factors—the change in temperature, the mass of the system, and the substance and phase of the substance.

How do you determine the thermal energy of an object quizlet?

Thermal energy of an object is the sum of the kinetic and potential energy of all of the particles that make up an object.

What are the three factors affecting thermal energy quizlet?

What are the three factors affecting thermal energy? Temperature, State, and Mass.

What factors determine the total energy of a substance?

A substance’s total thermal energy depends on its temperature, number of atoms, and physical state. More atoms and higher temperature mean more thermal energy. If all other conditions are the same, substances in gas form have the most thermal energy, followed by liquids, then solids.

What two processes occur due to less thermal energy?

Boiling and evaporation are processes that change a liquid to a gas. The opposite process also occurs. When a gas loses enough thermal energy, the gas changes to a liquid, or condenses. The change of state from a gas to a liquid is called condensation.

How can you tell if two objects are in thermal equilibrium quizlet?

when two or more objects are in thermal equilibrium, then the objects have the same temperature. when two or more objects are in kinetic equilibrium, then the objects have the same temperature.

How can you tell if two objects are in thermal equilibrium * hint think of what word is in equilibrium?

The thermal energy will flow in that direction until the two objects are at the same temperature. When the two systems in contact are at the same temperature, we say they are in thermal equilibrium.

What causes thermal pollution?

A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. When water used as a coolant is returned to the natural environment at a higher temperature, the sudden change in temperature decreases oxygen supply and affects the ecosystem.

What are the factors that influence the thermal efficiency of a gas turbine engine explain?

The three most important factors affecting the thermal efficiency are turbine inlet temperature, compression ratio, and the component efficiencies of the compressor and turbine. Other factors that affect thermal efficiency are compressor inlet temperature and combustion efficiency.

How does thermal energy flow?

Thermal energy typically flows from a warmer material to a cooler material. … Conduction transfers thermal energy through direct contact. If two objects are placed in contact with each other, thermal energy flows from the warmer object (with faster-moving particles) to the cooler object (with slower-moving particles).

What two factors determine the amount of energy transferred by an electric oven?

Here are the factors that affect the rate of conduction:

Temperature difference. The greater the difference in temperature between the two ends of the bar, the greater the rate of thermal energy transfer, so more heat is transferred. …
Cross-sectional area. …
Length (distance heat must travel). …
Time.

Which two factors affect the amount of thermal energy an object has apex?

An object’s thermal energy is dependent upon its temperature and mass. The higher the temperature of a given quantity of a substance, more is its thermal energy.

What factors affect the ability of a substance to transfer thermal energy to heat or be heated by its surroundings?

The difference in temperature, the total thermal energy, and the thermal conductivity all affect the ability of a substance to heat or be heated by its surroundings.

What has more thermal energy?

If two objects made of the same substance have different masses or temperatures, you can determine which has more thermal energy. If the objects have different masses but are otherwise the same, the one with more mass has more thermal energy.

What Cannot determine thermal energy?

No thermal energy can be removed from an object. List the three things that determine thermal energy. The temperature of an object, the number of particles in an object, and how the particles are arranged.

How do thermal energy and temperature differ?

Temperature is the measure of the average kinetic energy present in the molecules of the object. Thermal energy determines the total kinetic energy of the molecules present in an object.

What three factors influence the thermal energy of an object when is thermal energy greatest?
