Does deposition require heat?

Deposition does not require heat. Depositions simply requires that something be deposited in an area other than where it came from.

What are the five sources of light and heat?

1. The main source is the sun. Even though rocks seem like they emit heat, they really got their heat initially from the sun. 2. Radioactive substances emit their own energy and heat. 3. Warmblooded animals emit heat. However, they make the energy from the food they eat which ultimately came from the sun. 4. Electricity. Electricity can be used to make heat and light. 5. Other stars from other solar systems emit their own light.


What is the efficiency of 153 J and 185 J?

If 185 J went in and 153 J came out (with 32 J lost to heat), the efficiency would be 153/185, 0.827 or 82.7%.


How is heat transferred around the body?

Heat is created in the body as a by-product of the electro-chemical processes of the various sub-systems (e.g., cardio-vascular, pulmonary, skeletal, etc.). So by activity or simply by living (i.e., our basal metabolisms), our bodies create heat, which is why we're called "warm blooded." But without heat transfers and regulating systems, our bodies could easily overheat, which we call fevers. So our cardio-vascular system carries heat away through the blood stream. Our pulmonary system does it by exhaling warm breath whose heat came from the blood that flows through the lungs to release CO2 and gain oxygen. And our skin removes heat through radiation and through the evaporation of perspiration. The thermostat for regulating that heat is the hypothalamus section of our brains.
