What temperature is required to transfer waste heat to the environment for a heat engine to be 100 percent efficient?

A heat engine can never be 100% efficient due to the second law of thermodynamics, which states that some heat energy will always be lost to the surroundings. The temperature required for maximum efficiency is the temperature of the heat source for the engine. The efficiency of a heat engine is determined by the temperature difference between the heat source and the environment.


How does the refrigeration cycle in a heat pump work to transfer heat from a lower temperature source to a higher temperature sink?

The refrigeration cycle in a heat pump works by using a refrigerant to absorb heat from a lower temperature source, such as the air outside, and then transferring that heat to a higher temperature sink, such as the inside of a building. This process is achieved through the use of a compressor, condenser, expansion valve, and evaporator, which work together to circulate the refrigerant and facilitate the transfer of heat.


What direction heat moves from an inner source?

Heat moves from a higher temperature to a lower temperature, so it will radiate outward from the inner source towards the surrounding environment. This is known as heat transfer by conduction, convection, or radiation depending on the specific medium and conditions.


How do you calculate The Time required To heat liquid?

The time required to heat a liquid depends on the initial temperature, desired final temperature, heat source power (in watts), and mass or volume of the liquid. The formula to calculate this time is: Time = (mass or volume) * specific heat capacity * change in temperature / heat source power.


What happend when a convection current detector came near a heat source?

When a convection current detector comes near a heat source, it will detect the movement of air or fluid caused by the temperature difference. This movement creates a convection current around the heat source, which the detector can measure to indicate the presence and intensity of the heat source.

How can I build a simple calorimeter?

To build a simple calorimeter, you will need a container to hold water, a thermometer to measure temperature changes, and a heat source to generate heat. Place the heat source under the container, measure the initial temperature of the water, and then record the temperature change as the heat source warms the water. This will help you calculate the amount of heat energy released by the heat source.


How is heat related to temperature?

They both have something to do with thermal energy.


Temperature when there is absolutely no heat energy at all?

That's the definition of "Absolute Zero".


What is the effect of the time it takes to boil 16oz of drinking water by varying the temperature of the heat source?

If you increase the temperature of the heat source, you decrease the time it takes to boil the water.

How can I make a simple calorimeter?

To make a simple calorimeter, you will need a container to hold water, a thermometer to measure temperature changes, and a heat source to generate heat. Place the container with water on the heat source and measure the initial temperature. Apply heat to the water and record the temperature change. By measuring the amount of heat applied and the temperature change, you can calculate the heat capacity of the calorimeter.


What happens to water when heat energy is absorbed?

It's temperature rises according to the heat source.


Can temperature in the sink vary from the temperature in the dishwasher?

Absolutely. Every built-in dishwasher can heat water to a higher temperature than what dispenses from your kitchen sink.


Does the temperature falls as you move away from the source of Heat?

Yes, temperature typically decreases as you move away from a heat source. Heat dissipates through conduction, convection, and radiation, causing the surrounding environment to cool down.


Why does the auxiliary heat come on in my heating system?

The auxiliary heat in your heating system comes on when the primary heat source, such as a heat pump, is unable to meet the desired temperature setting. This usually happens during very cold weather or when the primary heat source is not functioning efficiently. The auxiliary heat helps to supplement the primary heat source and maintain a comfortable temperature in your home.


Temperature vs distance from an heat source at 1000 C?

As you move further away from a heat source at 1000°C, the temperature decreases gradually due to the dissipation of heat into the surrounding environment. The rate of temperature decrease is influenced by factors such as the material through which heat is transferred and the efficiency of insulation. The temperature will continue to decrease the farther you move away from the heat source, following the principles of thermal conduction and convection.


Are snakes coldblooded?

Yes they are - the need an external heat source to raise their temperature.
