### How do you measure the Temperature of a Black Hole?

A black body is a hypothetical object that absorbs all incoming radiation. The temperature of the black body is determined by the amount of radiation absorbed.

A black hole is a black body that obeys emission and absorption principles. The temperature of a black hole is determined by its mass and how it emits Hawking radiation.

The following is the formula for calculating the temperature of a black hole: T = ℏc3/(8πGMKb)

• Where, M be the black hole mass
• ℏ is the reduced Planck constant approximately 1.0545718001 x 10-34
• c is the speed of light
• G is the universal gravitational constant and value is 6.67408 x 10-11
• Kb is the Boltzmann constant and value is 1.380649 x 10-23
• T is the black hole temperature

### How to use the Black Hole Temperature Calculator?

• Enter the mass or the temperature of the black hole.
• Using the constant values of universal gravity and Boltzmann constant and Planck constant to calculate the unknown values.
• Press the calculate button to get the result.

### Black Hole Temperature Calculation Examples

Question 1: If the mass is 30 times weight of the sun. what will the black hole temperature?

Solution:

Consider the question,

Mass = 30 suns

We know that, The Black Hole Temperature formula is T = ℏc3 / (8πGMKb)

• Where, M be the black hole mass
• ℏ is the reduced Planck constant approximately 1.0545718001 x 10-34
• c is the speed of light
• G is the universal gravitational constant and value is 6.67408 x 10-11
• Kb is the Boltzmann constant and value is 1.380649 x 10-23
• T is the black hole temperature

Black Hole Temperature = 0.06172 * 10-6 / 30

Black Hole Temperature = 2.0573333333333333*10 -09Kelvin

Therefore,The black hole temperature = 2.0573333333333333*10 -09Kelvin

### FAQs on Black Hole Temperature Calculator

1. Is it possible that black holes emit temperature?

The event horizon is the most important characteristic of a black hole. Even the coldest objects emit some heat, but a black hole that captures light does not emit any heat. As a result, a black hole's temperature would be zero, which shouldn't be feasible.

2. What makes black holes so cold?

On the inside, black holes are extremely cold, yet on the outside, they are extremely hot. The astronomers see the very heated outside environment rather than the freezing cold environment inside because the radiation from the material covers the minuscule quantity of radiation escaping from the hole itself.

3. What about the formula for the temperature of a black hole?

The temperature of a black hole is determined by its mass and how it emits Hawking radiation. The following is the formula for calculating the temperature of a black hole: T = ℏc3/(8πGMKb)

4. What kinds of black holes are there?

Stellar, intermediate, supermassive, and microscopic black holes are the four types of black holes. A black hole is known to originate through stellar death.
