What can you conclude about the color and temperature of our sun

Explanation:

The color and temperature of a sun generally go hand in hand through what is known as the Color Temperature Scale. Each range of temperatures tends to display a different color. Our own Sun has a temperature of almost 5,800 Kelvin, which displays a white color when viewed from outside of our atmosphere. Other, hotter stars such as Rigel appear Blue since it gets above 10,000 Kelvin

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.

blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. as the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.
