Why is the sun hot?

Wouldn't be much use if it were cold.

What Causes the Sun to Give off Heat? The core of the sun is so hot and there is so much pressure, nuclear fusion takes place: hydrogen is changed to helium. Nuclear fusion creates heat and photons (light). The sun's surface is about 6,000 Kelvin, which is 10,340 degrees Fahrenheit (5,726 degrees Celsius).

The Sun has intense heat and pressure at it's core, and the hydrogen in the sun is undergoing fusion, being turned into helium. It's converting mass into energy, which we feel as heat and see as light.

Nuclear fusion generates a lot of heat.

Thermo-nuclear reactions give off a lot of heat, hence the "thermo" part of the word.

Because it is a giant thermonuclear reaction many times the size of Earth.

Nuclear Fusion deep in the Sun's core turns Hydrogen into Helium
Now speaking in a Squeaky Voice, Light Energy is produced as Photons
They bounce about within the Sun's confines, building up Energy until they get released at the Speed of LightSource(s): The Sun's Surface is 6,000 C, inside, Millions of degrees C

It's one giant explosion that will someday burn itself out. It's a ball of gas under incredible pressure. It has enough fuel to last long after humans are gone.

Because the sun is not ice. Lol

Nuclear fusion. Hydrogen + hydrogen —-> helium + energy.
